This thread is only for LG OLED TV models CX and GX.

The thread dedicated to gaming with 2020 CX and GX models is here.

Do you have problems with your panel uniformity, banding, or vignetting? The dedicated thread is here.

The E series was not refreshed in 2020.

The WX (Wallpaper), ZX (8K-Gallery style) and RX (Rollable) models will be treated in their own threads.

The new features and differences between the 2019 C9 and the 2020 CX:

  • built-in G-SYNC Compatibility (inherited from C9) - no firmware update required - will be supported across four 2020 model ranges (BX, CX, GX and ZX);
  • built-in HGiG Mode (inherited from C9) - no firmware update required;
  • new AMD FreeSync compatibility - available via a future firmware upgrade at the end of 2020 (the FreeSync level that is supported: "AMD FreeSync Premium" that provides: tear-free experience, at least 120hz refresh rate at minimum FHD resolution, support for low framerate compensation (LFC), low latency) - also is unknown if FreeSync will be made available to the C9;
  • new Filmmaker Mode - Auto/Manual - disables certain post-processing effects (such as motion smoothing, noise reduction, and sharpening) while perfectly preserving correct aspect ratios, colors and frame rates - the Filmmaker Mode feature will be accessible via a button on the remote control;
  • new Dolby Vision IQ support - "optimal picture quality as the creatives intended, no matter the ambient light environment or content genre" - Dolby Vision IQ isn't a separate picture mode, instead it will be automatically engaged in the standard Dolby Vision setting (Dolby said if you don't want the image to react to room lighting you can disable the LG's ambient light sensor manually) - Dolby Vision IQ is also supported by the 2019 models, but it not named that way in the WebOS menus;
  • new video processor - 'Alpha 9 Gen 3' - reportedly has a CPU 15% faster than Gen 2, and the GPU is 50% faster than Gen 2 - aka O20 (instead of the O18 chip used in the C8 and C9);
  • new 4K/120Hz 8-bit SDR 4:2:0 support via HDMI 2.0;
  • new 48" screen size available besides the now-classic 55, 65 and 77;
  • new G series model - Gallery OLED - as GX - "a whole different level with an ultra-thin form factor – the 65-inch model is a mere 20 millimeters (0.79 inches) thin" - replacing the E series that it will not be refreshed;
  • new 'Eye Comfort Display' certification from TÜV Rheinland as they are flicker-free (in SDR and HDR) and offer adjustability for blue light content.
  • new built-in hardware AV1 decoding (thanks to the new O20 chip) - the AV1 decoder apparently is limited to a maximum of [email protected], 10bit HDR (no 120p support);
  • new Apple TV app support - but the app will be available also for 2019 and 2018 LG TVs;
  • new GX series and up will offer hands-free voice control;
  • new version of WebOS 5.0 - some new features are already listed here;
  • new 'Sports Alert' feature - "to keep track of their favorite teams and schedules and notifying them as soon as a team scores" - it works via the internal tuner, not yet with external set-top boxes (update: LG says that it will work "with external tuners as long at the TV has the cable listings available and TV is set up to control the set-top box")
  • new "Auto Genre Selection" feature - the TV recognizes the type of content being played, be it a movie, sports or an animation, and adjusts the picture processing to suit.
  • The Home Dashboard has been cleaned up to make it easier to understand and arrange all your connected smart devices - the new Home Dashboard gives you quick access to inputs, media servers, and 'sound out' settings, you can also set-up voice routines such as "Good morning" that will activate multiple devices.
  • new 'Who? Where? What?' feature - only on US models - it’s powered by The Take.AI, an image and video recognition technology that uses artificial intelligence to allow the TV to highlight various elements of the content you're watching in real-time - it can tell you the location of a specific film scene or what coat or dress an actor or actress is wearing;
  • new Face Enhancing - feature taken from the ZX/RX models - not much is known about it;
  • Input lag is down to 5 ms with 120Hz input, according to LG;
  • HDMI-VRR range should be 40 to 120Hz for both G-sync and FreeSync;
  • HDMI-QMS should work but it's not certified yet;
  • new "Motion Pro" and "Cinema Clear" features - 120Hz BFI with three settings (High/Medium/Low) - with the biggest benefit that 120Hz BFI improves near-black uniformity by ~50% without any 60Hz flicker (like on C9) - sounds like more or less the same implementation that was reported for the 2019 models but that got pulled in the 11th hour;
  • Panel dimming algorithm has been tweaked;
  • No WebOS 5.0 update planned for previous models (as usual for LG...);
  • ATSC 3.0 tuner is available only on the new GX series and up;
  • Tone mapping enhancements - (compared with a C9 side by side) more intensity in small bright HDR light peaks, and daylight shots that look brighter for longer across the whole screen and better black levels during dark scenes - deep blacks seem to be delivered without crushing out much shadow detail;
  • AI Picture Pro - tweaked to do much less with native 4K sources that don’t really need much "help";
  • AI Sound Pro - tweaked to enhance vocal clarity and placement;
  • the ThinQ app for iOS and Android will be the preferred remote app for the 2020 models and newer - LG will phase out its 'LG TV Plus' mobile app - the ThinQ app is not able to control the 2019 models or older - this has changed, LG has added older models of OLEDs to the ThinQ app so now you can control the 2019 series - BUT be aware that the ThinQ app lacks the INFO (i) button
  • the WebOS 5.0 includes an edit mode that lets you add shortcuts to the left-aligned settings menu and a new Home setting option that lets the user select if the webOS bottom menu should appear automatically after standby
  • new manual 'Optimisation Settings' menu that will recommend optimal settings based on what you are watching at the time.
  • new support for Bluetooth-connected rear speakers as part of an "upgrade" to Bluetooth 5.0 (the C9 also has BT v5.0, so not a real upgrade over the previous model...) - but the current implementation is limited to upmixed surround so you cannot get native surround sound - you must use WiSA or an external system (receiver/soundbar) if you want true surround sound
  • LG has tweaked the dithering to make the occasional brightness flashing when the panel transitioned out of black less visible to the eye - this tweak makes the effect less visible - not perceptible from a distance - and banding is reduced to a minimum;
  • Much better screen uniformity than the 2019 generation, with very low vignetting or none at all - or dark patches/mura

Lost features
  • The DTS-HD internal decoder was removed;
  • Technicolor Mode was replaced with Filmmaker Mode;
  • Technicolor's 'Advanced HDR' format was removed (lack of market traction, probably);
  • The CX can't do 4K 120Hz 4:4:4/RGB 12-bit because the HDMI 2.1 FRL speed is limited at 40Gbps (instead of the 48Gbps that is available on the C9). The CX can still do 4K 120Hz 4:2:2 12-bit, 4K 120Hz 4:2:0 12-bit, 1440p 120Hz 4:4:4/RGB 12-bit, 1080p 120Hz 4:4:4/RGB 12-bit, and all other 12-bit modes that don't go over 40Gbps.
  • The new LG ThinQ app that can be used as a touch remote for the 2020 series lacks the INFO (i) button that was present in the "LG TV Plus" app

Expected, but unconfirmed features
  • WOLED panel stack improvements - change from the B-YG/R-B stack to the B-G/R-B stack - allows for more saturated colors and increased color gamut/volume (mainly on the Green) - no change from the previous C9 is detected;
  • DCI-P3 improvements - gamut increase from 99% DCI-P3 to 100% DCI-P3 - NO, the CX OLED panel covers ~ 96% of DCI-P3 - no change from the previous C9;
  • Rec.2020 improvements - gamut increase from 85% Rec.2020 - NO - the CX OLED panel covers ~ 71% of Rec.2020 - no change from the previous C9;

  • Improved power-off when connecting to a specific set-top
  • Improved noise when transferring video from the iPhone to the TV with the Airplay app
  • Improved volume reduction when setting the set-top box volume low (1 ~ 2)
  • Improved screen saver execution error
  • Unofficial - this update apparently resolves some DD+ sound drops from streaming apps when using an eARC capable audio sink (receiver/soundbar) - switching eARC to Auto instead of the Pass-through forced the app to switch to DD instead of DD+ (with no more sound drops a couple of times a minute)
- 03.00.65 - South Korea - June 2020
  • unknown changes
- 03.00.70 - S. Korea - June 2020
  • Improving the operation of certain eARC equipment with ARC

  • Improved lip sync distortion when using voice recognition button in voice mode, output mode
  • magic remote control / video image improvement when switching IP channel
- 03.10.20 - June 2020
  • Apple AirPlay improvements
  • Support AMD FreeSync (Premium level - see it in the additional settings in the Picture Settings menu) - AMD FreeSync Premium is a separate option, VRR can be enabled without it
  • Sport Alert improvements
  • Support ATSC 3.0 (WX/GX Model only)
  • Apparently, it fixed the Smooth Gradiation bug
  • Apparently, the elevated black level in DV is not fixed
  • Apparently, Instant Game Response gamma curve is still wrong
  • new internal test pattern generator for CalMan for calibration
  • some ARC/eARC bug fixes
  • some raised HDR/DV black issues fixed
NOTE: After the 3.10.20 update, FreeSync Premium option is added to the TV Settings, and if you have a FreeSync compatible source (like a Xbox), it will be set to On - that will disable Dolby Vision, because DV will NOT work if AMD FreeSync is enabled, so before going to watch any Dolby Vision content, or even UHD 4K content, you need to DISABLE Freesync Premium and THEN go into the app or video content.
- 3.10.41 - July 2020
  • unknown changes
  • probably a quick bugfix update
  • Apparently, the elevated black level in DV is still not fixed
  • Apparently, it fixed some bad HDMI-CEC interactions with Nvidia Shield

Engineering/Test firmware
- 03.10.70 ?

(1) The changelog information above is provided as-is, without any further explanation and only when I am able to obtain it. If the information listed above doesn't make sense, please don't ask for clarification, as I have none;

Features that are delivered:

  • 5.1/7.1 LPCM passthrough via eARC - delivered via 03.00.45 F/W update in April 2020 - for the 2019 gen this feature is in beta/test F/W
  • AMD FreeSync compatibility - available via 03.10.20 firmware update in June 2020 - for the 2019 generation (C9-E9) you need to use CRU to enable FreeSync;

Expected/Announced features to be delivered via firmware updates:

  • HDCP 2.3 - the CX is still at HDCP 2.2 level - HDCP 2.3 will be available via a future firmware update, probably at the same time with the C9;
  • Dolby Vision glows at brightness 50 - LG is aware and is working for a fix - Please be aware that raised blacks in DV is an old and recurring problem, is more a Dolby generated problem that LG's, and is present in a lot of TV's from various brands and years, SO, do not get your hopes high that it will be solved soon (2018, 2019 (and soon 2020) TV's owners still await their fix... - LONG TERM SOLUTION: if you don't calibrate the TV and see any raised blacks in any Picture Mode just lower the black level from 50 to 49. If you calibrate the TV it should correct this.;

Features that will never be delivered via firmware updates:
  • WebOS apps support for lossless audio - there will be no WebOS app support for lossless HD audio soundtracks such as TrueHD, TrueHD+Atmos, DTS-HD HR, DTS-HD MA or DTS:X - this is the same situation as for the 2019 models; The Alpha9 SoC has only an ARC capable audio output, so it cannot send lossless audio back to the receiver/soundbar, even if they are eARC capable, firmware updates cannot modify hardware limitations;
  • DTS/DTS-HD audio is not passed via eARC - LG was notified about this issue, hopefully, they will provide a fix via a future firmware update - We have further indirect info from LG: It's not a bug, they are not supporting it, just like Samsung - so it's not going to be fixed!;
  • DTS and DTS-HD support for USB and HDMI sources - the internal decoder is missing from the factory (as announced in the documentation) and probably it will never be added to the 2020 generation - what is puzzling is that DTS and DTS-HD is not even permitted to passthrough via ARC/eARC;
  • Full 48Gbps support - as of April 2020 the "12 Gbps on 4 lanes" from the Max Fixed Rate Link EDID is missing (the C9 has it) - if we believe the EDID values, the 2020 models support only 40Gbps links, not full 48Gbps;
More details about the lack of full 48Gbps support:
In a turn around from the HDMI 2.1 situation introduced with its 2019 4K TVs, none of its 2020 4K TVs, OLED or LCD, will carry ‘full bandwidth’ HDMI ports capable of handling HDMI 2.1’s maximum 48Gbps data rate. The 48Gbps rate is required to handle uncompressed 12-bit 4K at 120Hz with RGB 4:4:4 chroma sampling. LG tells me now, though, that while the HDMIs on its premium 2019 TVs were indeed full 48Gbps examples, all four HDMIs on the WX, GX and CX OLED TVs will instead handle 10-bit (rather than 12-bit) 4K at 120Hz with RGB 4:4:4 chroma sampling. This implies a likely 40Gbps data rate.
Here’s the official statement LG shared:
“While LG covered most of the HDMI 2.1 related specs in its 2019 TVs, including full bandwidth support in all of the HDMI ports for its 4K and 8K TVs, the market situation evolution indicated that real content that requires 48Gbps is not available in the market. Based on market situation, LG decided to re-allocate the hardware resources of 2020 chipsets optimizing for AI functions including CPU&GPU and supporting full bandwidth in only 2 ports of 2020 8K TV series (ZX series, NANO99, NANO97, NANO95). And the rest of the ports of 8K TVs and all HDMI 2.1 ports of 4K TVs have lower bandwidth than 48 Gbps but support up to 4K 120P 4:4:4/RGB 10bit. We apologize for not flagging this earlier to you.”
Attached are 2 screenshots from the LG US website:
1. LG OLED CX US web archive 2020-04-09 48Gbps mention.png - shows the original statement that the CX allegedly supports 48Gbps.
2. LG OLED CX US 2020-05-06 40Gbps correction.png - shows the same page with the new note about the actual 40Gbps support...

FAQ - Frequently Asked Questions


Q: When we expect to know the prices of 2020 models?
A: The MSRP prices are usually mentioned during the usual April launch event. The first available prices were available in Germany, on 4 March 2020, earlier than usual, as mentioned below. The US MSRP prices were made available by 16 March 2020, mentioned below.

Q: When we expect the first reviews?
A: LG usually has an April launch event - units are sent to reviewers at the same time. So the first reviews are expected sometime during April-May. The March 2020 Los Angeles launch event was canceled by the coronavirus epidemic, and the 2020 models were soft-launched and the first models (mostly 55" CXs) are already delivered in March 2020, with reviews starting to appear towards the end of March.

Q: When we expect the lowest prices for 2020 models?
A: The price evolution is similar each year and you can see the graph in the "TV yearly-price-tv-deals price evolution.png" attachment.

Q: When we expect the first 2020 models to be available?
A: The 2020 models will be on the market earlier than the 2019 models (US launch date was 11 March 2020, but no prices mentioned). In the US, the expected launch dates are (for Value Electronics), in order of the release:
  • 55" + 65" CX early March
  • 55" + 65" GX end of March
  • 77" CX mid-April
  • 88" ZX mid-April
  • 77" GX end of April
  • 77" ZX early May
  • 48" CX late May June

Q: What are the official US launch prices (MSRP) and availability dates for the CX-GX 2020 models?
A: Prices were published by LG on 16 March 2020
OLED77GXPUA - $5,999 - Available April 2020

OLED48CXPUB - $1,499 - Available (late) June 2020

A table with launch prices is also attached to this post as "LG 2020 4K OLED - suggested retail prices - flatpanelshd.png"


Q: How can I screw up my TV with ease?
A: If you have too much time at your disposal or you suffer from insatiable curiosity syndrome... DO NOT MESS WITH IN-STOP submenu! PLEASE BE AWARE THAT entering Service Menu and choosing the In-Stop submenu will reset everything but the currently installed firmware (there is no factory stored version, so you can't go back). You will lose the UTT parameter and the time to the next JB/Pixel Refresh!!! Normally, only a panel change will require a FULL TV RESET - PLEASE DO NOT USE THE IN-STOP SUBMENU IF YOU DO NOT KNOW WHAT IT DOES!!! IN-STOP IS NOT THE SAME AS THE RESET TO FACTORY SETTING THAT IS AVAILABLE TO THE OWNER IN THE SETTINGS MENU!!!

Q: What is Dolby Vision IQ?
A: Dolby rolled out a new augmentation to its Dolby Vision HDR format called Dolby Vision IQ, which is designed to fix the problem that in some situations it can look too dark by automatically adjusting the picture in response to room brightness. Dolby Vision IQ isn't a separate picture mode, instead, it will be automatically engaged in the standard Dolby Vision setting (Dolby said if you don't want the image to react to room lighting you can disable the LG's ambient light sensor manually);

Q: Dolby Vision IQ is available on both "Dolby Vision Cinema" and "Dolby Vision Cinema Home" profiles?
A: No, Dolby Vision IQ is available only in the "Dolby Vision Cinema Home" profile, the AI Brightness control is grayed out with "Dolby Vision Cinema" but available with the "Dolby Vision Cinema Home" profile;

Q: What is the most accurate Dolby Vision profile available on the CX?
A: The "Dolby Vision Cinema Home" profile on the CX does not follow PQ correctly regardless if Dolby Vision IQ is active or not. The only correct mode is the "Dolby Vision Cinema" profile;

Q: Isn't AI Brightness supposed to function like Dolby Vision IQ adjusting for room lighting??
A: The AI Brightness feature is used for HDR10/HDR HLG content, but the sensor that the AI Brightness feature is using is also used by the Dolby Vision IQ feature for the DV content.

Q: What is Filmmaker Mode?
A: UHD Alliance's Filmmaker Mode is a separate mode designed to offer a picture that "maintains the creative intent" by disabling stuff like the soap opera effect. Filmmaker Mode does not exclude Dolby Vision HDR. Filmmaker Mode mode works by "disabling all post-processing (e.g. motion smoothing, etc.) and preserving the correct aspect ratios, colors and frame rates". Filmmaker Mode can be enabled in one of two ways: either automatically or with a dedicated button on the remote. To work automatically, the content itself needs metadata that tells the TV to turn on the mode, and for that to happen service providers like Netflix and Apple iTunes need to be on board.

Q: What is the purpose of the Pixel Refresh function?
A: Regardless of what you may have read or told, the main purpose of the Pixel Refresh function is NOT to minimize the Image Retention or Burn-In effects. The fact that Pixel Refresh has an effect on the Image Retention or Burn-In is a positive side-effect, but NOT the main purpose of this function. The main Pixel Refresh function purpose is to deal with the natural unevenness of the brightness of the OLED pixels in time. That unevenness needs to be leveled so the panel has the same brightness all over its surface so that the entire panel ages in a uniform manner. There is no need to manually run Pixel Refresh, just let the TV execute this function automatically!

Q: How often should I run the Pixel Refresh?
A: You should NOT run the Pixel Refresh often, only if you need it, or told so by a qualified person - because the Pixel Refresh function shortens the lifespan of the panel. Pixel Refresh runs automatically at every 2000 hours of content viewing and there is no need for the owner to run Pixel Refresh at other intervals of time, regardless of what you have read on the Internet or told by salespeople.

Q: What Pixel Refresh actually does?
A: In short, a newly-minted OLED panel is powered and each pixel is measured for (1) voltage across OLED cell and (2) current through OLED cell, compared with neighboring pixels and the voltage+current levels are leveled for each pixel so that the panel has good image/brightness uniformity - and then the levels are stored in a non-volatile memory on the panel electronics board (not on the TV mainboard).
That new panel will end up in a new manufactured TV - that TV will be used and, in time, some OLED cells will age differently than the neighboring cells, thus image non-uniformity will start to appear. This is where the Pixel Refresh function enters the arena.
When the Pixel Refresh function is run automatically or manually by the user, it checks voltage+current differences between the stored values and those measured for each OLED pixel and tries to normalize them. The OLED panel has an additional compensation applying circuit for each pixel and a separate sensing IC (Integrated Circuit) that interprets the measured values. Increased current through the cell is associated with OLED cell aging, and an algorithm adjusts the current and voltage to compensate for that aging. The new compensation values are stored separately (in a Flash memory) to the initial ones. The pixels that have very high voltage/current differences are "leveled down" - that results in an even field of pixels across the panel. After the pixels that were "high" are leveled down, the Pixel Refresh brings up the voltage/current back to full brightness without the danger of overdriving the ones that were "high" (the measured/calibrated brightness of the panel will not be affected). The whole Pixel Refresh process is done in vertical batches, which is what causes the panel banding, and why the bands "move" over time. If the Pixel Refresh would not run, the brightness uniformity of the panel would be affected in time - over months of use the panel would just get zones that are dimmer than others. The Pixel Refresh has a big downside, though, it shortens the lifespan of the panel, the operation of leveling down of the voltage/current values is a BIG stress for the panel - this is why you should NOT be using the Pixel Refresh function repeatedly or at short intervals of time (the automatic run at 2000 hours is just enough and it would ensure a long lifespan of the panel).

Q: Are you sure that the Pixel Refresh function will not affect panel brightness?
A: The RTINGS torture tests have proven that the measured/calibrated brightness of the panel will not be affected by the execution of the Pixel Refresh function - even when the Pixel Refresh was run on weekly basis (this is strongly NOT recommended!!!). BUT - there is always a but - since every Pixel Refresh run will shorten the lifespan of the panel, the aging of the panel will accelerate, and the moment that the panel will not be able to maintain the same brightness as it was new will come sooner than if the Pixel Refresh has been run automatically (at each 2000 hours of use). So, the lesson here is the same: do NOT run Pixel Refresh manually - let the TV manage the natural panel aging automatically (by running the Pixel Refresh every 2000 hours of use).

Q: Is there a way to know if Pixel Refresh actually ran after doing a "Start Now"?;
A: 1. It is NOT advisable to manually run Pixel Refresh without some serious reason - such as:
  • big panel non-uniformity (may be experienced as DSE - Dirty Screen Effect)
  • splotches of brighter/darker content (may be experienced as clouding)
  • vertical banding seen in the content
  • other types of panel non-uniformity
2. You will see a notification when the Pixel Refresh cycle has completed or was interrupted.
3. The Pixel Refresh process is logged internally and can be seen in the Service Menu.
4. The Pixel Refresh cycle will take significantly longer time - 20-30 minutes or more - duration depends on how much pixels are affected by uneven aging.
5. The Pixel Refresh cycle has a limited effect on panel Burn-In and the Pixel Refresh will not completely "cure" an already Burned-In panel.
6. Please read this FAQ for more details.

Q: My panel was replaced - but the UTT wasn't reset - anyone knows how to reset?;
A: The UTT Reset function was available in the Service Menu - InStart - System pages, but it was removed long ago (in 2016 or 2017). Now the only way to reset the UTT is by resetting the whole TV to factory settings by entering Service Menu - InStop menu. This will reset everything but the currently installed firmware (there is no factory stored version, so you can't go back). Normally, a panel change will require a reset to factory settings and redoing the calibration (only if the TV was previously calibrated) since the new panel can have different image characteristics versus the old panel.

Q: What are the effects of OLED Motion Pro / BFI on the image (without a 120Hz source)?;
A: In LG CX there are five levels for OLED Motion Pro (Off, Low, Medium, High and Auto).
'Low' will reduce the brightness by 15%.
'Medium' will reduce the brightness by 40%.
'High' will reduce the brightness by 75%.
'Medium' is more effective at increasing motion resolution than 'Low' but brightness obviously takes a more significant hit.
The 'High' setting produces visible flicker and is not recommended for any type of content.
The 'Auto' option varies between 'Low' and 'Medium' but avoids 'High'.
At its two lower settings (Low and Medium) the BFI system is definitely useful now, as opposed to BFI in 2019 OLED TVs, but improved motion resolution comes at the expense of a reduction in brightness that is a little higher than what was previewed on the 2019 OLED TVs (but later removed from production firmware).
Also, note that by engaging 'OLED Motion Pro' input lag increases slightly to 22 ms.

Q: I want to use a 48CX as a PC monitor. Do you have some advice about it?;
A: Yes, if you care for your TV/monitor, do NOT run the PC in HDR mode all the time! It is common knowledge that the higher you set the luminance, the bigger your risk of burn-in and/or panel degradation. And HDR mode will set the luminance higher than SDR, and that will shorten the life of the panel much faster than SDR. So keep your Desktop in SDR and let the apps/games switch to HDR or if automatic switching is not available, switch to HDR only if you need it and then return to SDR. This advice is, of course, useful for all panel sizes, not only 48".

Q: Do LG OLEDs support LFC?
A: the last "official" statement of LG concerning LFC was: ''Our 2019 OLEDs would support VRR and can now support G-Sync but not LFC at this time. I have not been made aware of LFC being added to OLED TVs in the future but I will submit to suggestion up to the factory to see what can be done.'' So, we cannot expect LFC to be supported by the 2020 generation. Additional info: "Regarding LG's OLED TVs and Freesync, It has been discovered just recently that, despite the C9 not having Freesync support in any fashion and only supporting HDMI Forum VRR, if one uses the PC program "Custom Resolution Utility (CRU)", then you can actually enable Freesync-over-HDMI from a PC AMD GPU, and with LFC to boot! (because, as I mentioned, AMD implements LFC on the GPU-side of things)" So, since CX/GX are based on C9, LFC can work under some conditions.

Q: Does the AMD FreeSync Premium feature works with HDR?
A: Yes. Yes, it does.

Q: Do the 2020 OLEDs still have the excessive banding in 4:4:4 HDR video?
A: Apparently, the CX has not the same issue as older OLEDs were if the input type is changed to a PC and the name is PC, 4:4:4 processing is turned on and there would be excessive banding in HDR video.

Q: What are the evolution trough time for LG's WOLED banding and tinting?
A: 2017 was bad for banding;
2018 banding improved and so did tinting;
2019 banding improved further but tinting got way worse;
2020 looks good for both banding and tinting;

Q: Those that play games on the CX/GX, do you adjust the Logo Luminance Adjustment any higher than the default Low?
A: The adjustment is about the delay of time it takes to when the Logo Luminance kicks in - not the intensity of the effect it has on the image (dimming of the static elements). Low = standard delay until the logos are dimmed, High = lower delay until the logos are dimmed. So, you are protected with either Low or High - you choose only the speed.

Q: I'm seeing a lot of comments about "raised blacks", "crushed blacks" and "floating blacks". What, exactly are those terms referring to?
A: "raised blacks" and "floating blacks" are two terms both referring to the same problem. It's when what should be* black, is lifted to a higher luminance so that it's very dark grey instead of perfect black. Can be caused by bugs (eg with Dolby Vision from some devices and not others). A common reference is to notice that the black bars on a 2.35:1 movie, where there is no normal picture content, aren't black. It can also be deliberately mastered into the content by the creators, and it is their correct intent (like with the color of space in Star Wars is not proper black), so anyone who says it's a mistake and tries to "fix" what was actually correct is chasing their tail. "crushed blacks" is when many different very dark greys are all crushed down to the same dark color. If someone is wearing fully black clothes, you should still be able to see the creases in their clothes for example when the light shines on them. If you have a "crushed blacks" problem, it'll all be mashed into the same color black and you lose all of that detail. The thing you are losing is also called "shadow detail".

Display Calibration

Q: If LG releases some substantially updated firmware to address some PQ issues, will it impact a prior professional calibration?;
A: You can never be 100% sure that a firmware update will not affect an existing calibration but generally they don't but there have been cases where they do. With the CX we are aware of some of the coming changes and they are not supposed to affect the calibration. Most manufacturers are very aware of this problem and usually take steps to avoid issues in this regard.

Q: If I want to revert the TV to the original factory picture parameters, do I have to reset the TV to the factory settings?;
A: Yes, but doing so you will lose ALL the TV settings. You do not need to do a full Factory Reset on the 2019/2020 gen. LG OLEDs! A factory reset will clear any user-uploaded 1D and 3D LUTs from all picture modes, and the TV will then use the LG 1D and 3D LUTs. The TV will always use both a 1D and 3D LUT in its processing pipeline, it's just a question of which ones: (1) Yours (which are fixed LUTs and only correct when used with the single state the TV was in during the calibration ie Contrast=85 Brightness=50 Colour=50), or (2) LG's (which are dynamic but not specific to your individual panel). The 2019 or 2020 generation owners can restore the LG factory LUTs in a single picture mode by just doing a "Reset" for that one picture mode in that mode's menu, and then not reconnecting with Calman (doing so with the same picture mode will re-load the user LUTs). For 2018 or older gen. owners, a full Factory Reset of the entire TV is the only way to get the LG LUTs back.

Q: I have a calibrated TV. But I had reset it to the factory settings. Now the TV is brighter than it was calibrated. Why?;
A: The reason why the picture looks brighter after the reset if the set was calibrated is the white point probably was vectoring towards blue from the factory.

Q: If the "cinema home" option with Dolby vision on streaming apps like disney+ or Netflix is supposed to force TruMotion to clear motion with no option of turning off (greyed out) whereas the regular "home" mode allows you to adjust both the real cinema and TruMotion settings. Why?;
A: You need to disable Auto Genre Selection in the AI Service menu ( GENERAL->AI SERVICE-> disable AUTO GENRE SELECTION) and now you can change/disable clear motion settings.

Q: Where are the basic @D-Nice image setup recommendation settings?;
A: Those "SDR Settings with whitepoint target of x0.3095 y0.3290" settings are at the 504 post number.

Q: Can anybody confirm what the Auto Genre Selection feature does? I was playing with this setting on the two sets that I have. On one of them toggling it on and off was doing nothing but on the other, it looked like it was altering the color temperature of the panel towards a cooler direction. Either that or it was brightening the panel slightly. I'm not sure. Both sets on the firmware version of 3.10.20. A bit strange that I'm only seeing the image change on one of the panels when toggling AGS on and off. On the other, it doesn't seem to make a difference even though the content being played is the same.;
A: Yes, there are some reports that AGS does modify those image parameters (maybe others too).
Only LG knows for sure what is the algorithm. And is not strange at all for two TVs not behaving the same with AGS turned On - it is just the way cloud-driven systems are made - there is some local computing done and some computing done by "the cloud" - so, one TV had sent and receive the required data to make the adjustments, but the other TV did not. Maybe those two TVs will never be "in sync" with each other..., even if the location is the same...


Q: When I play a video with a DTS audio soundtrack via USB I have no audio;
A: The support for DTS/DTS-HD audio was removed from 2020 models;

Q: Can someone with a PC and who's familiar with CRU add the DTS and DTS-HD entries back in?;
A: I tried this and the TV popped up a notification "Audio format is not supported", so, no, you can't hack DTS support back to the TV.

Q: I'm confused. So a DTS decoder is required to simply pass through a DTS signal? If the signal is just "passing through" and not being decoded, why is a decoder necessary?;
A: If the TV accepts DTS audio it must at least decode that audio so that the internal speakers do some noise when DTS audio is playing - regardless of the actual source of audio is external or internal. Pass-Trough via ARC/eARC has the same requirements (the right EDID + a minimal DTS-to-stereo decoder) even if the final destination of audio is not the internal speakers.
The DTS license probably must include at least those two items:
1) the acceptance of the said audio format (in the form of the EDID);
2) a core decoder of the said audio format;

Q: Can I configure the LG Plex internal app to transcode DTS audio to multichannel PCM and pass it to a Denon AVR via HDMI eARC?;
A: The WebOS apps would be unable to transcode DTS-to-anything because no DTS audio would be allowed to access the audio system of the TV. Transcoding must be performed outside of the TV, on the server/NAS/whatever.


Q: The 48" model has all the features of the bigger (55/65/77) models?;
A: Yes, the 48-inch CX will be an exact match, save for the smaller format (and higher pixel density). It has the same panel, same processor, same design and same features. There is nothing missing;

Q: Is there a way to see how many hours the TV has on the clock? Can't find it in the settings menu.;
A: The non-US models have the UTT parameter hidden in the Service Menu. Only the US models have the UTT exposed in the WebOS settings menu.

Q: Plugged in and got the 3 flashing red lights then nothing; Waited 24 hours to plug in and still had 3 flashes after trying to power up manually or with remote.;
A: 3 flashes of the red Stand-By LED is a fatal error - and it can mean anything, from a failing panel or a bad power board. Most of the time the mainboard is faulty. The TV needs diagnosing or if in warranty, replaced.

Q: I need some measurements before I can mount my TV up, where can I found them?;
A: For the GX model there is a Gallery Series Mechanical Drawings PDF template posted by LG USA. No such drawings/templates were found for other 2020 models.

Q: Is it really an issue if don't transport your OLED standing up? Especially when brand new in the original box? From the unboxing videos I have seen, the CX series has tons of Styrofoam all over the screen and these TVs are shipped all over the world in huge pallets, would putting the TV diagonally or flat on the way home from the store really cause damage to it?;
A: I brought a CX65 home laying completely flat in the bed of my truck without an issue however, these displays are comically thin and bendy everywhere except the speaker/io assembly. I don't know if I'd take the chance of transporting it laying at an angle where it could flex with every bump in the road. If I'm not mistaken, they're stacked vertically on pallets for shipping, which minimizes the amount of flex.

Other functions

Q: The 2020 series have the same Host/HDMI diagnostics menu as the 2019 series?;
A: Yes. With the remote go to Settings - Channels, then highlight the top menu option within Channels and press the numeric button "1" for five times (11111) to display the hidden "Host Diagnostics" screen (hardware, tuner, Wi-Fi)
--- to get to "HDMI Diagnostics" menu use the arrow buttons on the circle surrounding the scroll wheel and highlight the "HDMI Mode" submenu, click OK/Enter (scroll wheel) and a second screen ("HDMI Diagnostics") appears (general, video link, audio, phy, hdcp, scdc, avi info frame, spd, hdr)
-- Notes about the hidden Diagnostics menu:
----- HDMI Diagnostics - General section - for some reason DolbyVision shows up as SDR;
----- HDMI Diagnostics - PHY section - the Bandwidth is per channel so multiply by 3;
----- HDMI Diagnostics - Video(LINK) section - Total Res is hTotal and vTotal (includes blanking);
----- HDMI Diagnostics - SCDC section - with an HDMI 2.1 source the "Lane3 Lock", "FRL Rate" and "FRL Start" will show 1, instead of 0 - proving that you feed the TV a 48Gbps signal;

Q: I’d like to stop the TV from controlling the power on my {insert device name} but I can’t seem to find the settings anywhere;
A: The HDMI-CEC setting that controls this is located here: Settings > Connection > Device Connection Settings > Auto Power Sync

Q: How do I rename the inputs on the new 2020 models?;
A: Click the home button on the WebOS nav, and on that screen, click on the gear icon on the top right and then click edit.

Q: How can I add a shortcut to a command to the WebOS menu? For quickly turning off the screen, for example.;
A: When you click on the settings button once, you can click on a pencil (edit mode) and then click on "+" and select "Screen Off" to add to the menu. If you don't have "+" to add an item, you need to delete one of the settings menu items and it will allow you to add another item instead.

Q: Is there a way to use my own photos as a gallery instead of those pictures that LG has built-in?;
A: Go to the LG Gallery app and you can download groups of images to rotate. Also, running the app will display a slideshow of your downloaded images without the "No Signal" window. Also, the My Photo feature in the Gallery app that lets you put your own images on a USB drive so they can be used to create your own personal screensaver gallery instead of using the galleries in the app.


Q: How can I use the four Red, Green, Yellow, and Blue colored buttons on the Magic Remote for other features than the Teletext?;
A: If your Blu-ray player accepts, those buttons can be used to set or delete bookmarks - also, on Xbox, those buttons are mapped to the associated gamepad buttons: B - A - Y - X;

Q: Can you use an LG Signature remote with other LG models?
A: Yes, the LG Signature remotes for Z9 or ZX work just fine with other models, such as C9, CX, or GX - might work with any Magic Remote compatible TV. The model numbers for the 2019 LG Signature Z9 remote are AKB75755301 / AN-MR19PR/ AN-MR19BA / PM19. The model numbers for the 2020 LG Signature ZX remote are AKB75895301 / PM20GA.

Q: There's a feature that will resume paused video in Netflix (although I think in other apps too) when remote is moved. Is there a way to disable this behavior?
A: This unpause feature works only in Netflix - on other streaming apps the remote movement only brings the TV out of screensaver mode. LG has stated that this feature is to prevent burn-in (maybe it will be added to other apps in the future...). This feature cannot be disabled or controlled in any way. You can only mitigate this issue by setting the remote to a very stable surface and that surface should not be shared by smartphones or other objects that can vibrate or induce vibrations.

Q: How can I use the Magic Remote to control my AVR and the sources attached to it? When I set up the Universal Remote Control on the TV I cannot control anything and I do not see/control the AVR inputs on the TV. How do I use CEC Pass-Trough?
A: If a device cannot be controlled by the Universal Control you can remove this option. In order to disable this option, you first have to disable the "Auto Device Detection" feature which can be found under "Connection - HDMI Device Settings - Auto Device Detection" (on the 2020 CX it might be in another place). This is necessary since the TV will otherwise automatically enable "Universal Control" for all devices that are detected/connected. Once you've disabled the auto-detection temporarily, shut down and unplug your device from the HDMI port. After you've reconnected your device everything should be fine. The "Device Connector" should then no longer show a "Magic Remote" icon in a bubble on top of the device selection.
You can re-enable Auto Device Detection after that if you prefer. The Universal Control is not compatible with all the CEC-enabled devices and for whatever reasons, it interferes with the CEC standard commands and blocks pass-trough.

Known problems


P: Plex or internal video player do not play lossless audio such as Dolby TrueHD or DTS-HD soundtracks
A: The internal apps do not support lossless audio and that support will not be added - the only way the TV will play lossless audio is via HDMI pass-through from an external source - "LG engineers, have stated that Dolby TrueHD can ONLY be passed through from a connected device - not an app such as Plex. They assert there can be no fix for this as an app is not considered "passthrough" and requires the decoder."; The Alpha9 SoC has only an ARC capable audio output, so it cannot send lossless audio, firmware updates cannot modify hardware limitations;

P: USB media player does not play lossless audio (but lossy Atmos soundtracks work)
A: See the above answer;

P: The internal DLNA service does not play lossless audio
A: See the above answer;

P: The DTS/DTS-HD internal decoder was removed
A: The TV will be unable to decode any DTS audio that originates internally (apps/streaming/USB), but it should pass the DTS audio to an external decoder (AVR/soundbar) - this has been reported to LG (on April 2020) and they are aware - we have no idea if they are going to add DTS at a later date but it's certainly possible - NO, the TV will not allow any external source to send DTS/DTS-HD audio so Pass-Trough via ARC/eARC is not possible (the source will try to negotiate other audio formats - if the source is capable it will convert DTS to MultiCh-PCM or 2ch PCM);

P: The internal player cannot handle the omission of DTS/DTS-HD support - if you play a file with DTS it says that your network or internet connection is down.
A: The DTS/DTS-HD internal decoder was removed;

P: If you play files that have DTS audio with the internal video player via USB, the TV just says "This video does not support audio."
A: The DTS/DTS-HD internal decoder was removed;

P: If you send files that have DTS audio via LG Smart Share app on the TV it does not work
A: The DTS/DTS-HD internal decoder was removed;

P: The CX eARC is not capable of DTS/DTS-HD passthrough - but TrueHD works
A: This should not happen - the lack of DTS/DTS-HD internal decoder should not impact the eARC passthrough - the C9 did pass all codecs except the MC-LPCM;

P: The CX eARC is not stable when is passing 5.1/7.1 LPCM from Xbox One
More info: "whenever I turn off the Xbox One and turn it back on or or switch over to a different source device and then back to the Xbox One X input it goes back to Dolby Digital+ based Atmos. I discovered that turning off eARC and turning eARC back on again within the CX's sound settings brings it back to uncompressed LCPM 7.1/Dolby TrueHD based Atmos. To rule out the possibility of either the AVR or the cables being the culprit, I tested this on two different eARC capable AVRs including my Sony STR-DN1080 and Denon X3600H in addition to a range of HDMI cables which include Belkin's 48Gbps rated HDMI cables and had the same issue." This issue has an open ticket on the LG Comunity site.

P: Sound pops from the speakers as video/audio changes format with eARC enabled
A: Apparently caused by the 3.00.60 F/W update. Disabling eARC resolves the issue.

P: The 2020 models still have glaring eARC bugs that were not fixed even after 3 eARC related firmware updates - current F/W 03.10.20 - June 2020
More info: "No matter the source streaming service (netflix, disney+,etc), no matter which device (appletv or roku), if the native encoding is something other than DD or DD+, the Denon says its DTHD but regardless, there is no audio coming through." ------ "I currently have this exact same issue with my Denon as well. Old shows default to DTHD and no audio whatsoever." ------ "For no apparent reason, all sources will drop to stereo and even power cycling the entire system does not fix the problem. The only way to get multi-channel working again is 5 minutes of (seemingly) random flipping of switches in the CX's sound menus. If there's a magic pattern to make everything happy again, I haven't found it yet."
A: There is no solution at the moment.

Display - Video

P: Trumotion is not selectable with G-Sync on, but if you turn G-Sync off, it'll become selectable. When you turn G-Sync back on OLED Motion Pro will stay on.
A: -

P: When in 4k 120hz (4k 120hz 4:2:0 8 bit via HDMI 2.0b GFX card), the bottom and right side of the screen are cut off. Turning off Screen Shift fixes this, but turning the TV off then back on cuts it off again. Screen Shift remains off but it can be fixed by turning it on then off again.
A: -

P: Normally BFI (OLED Motion Pro) isn't selectable with G-Sync on. I turned it off then turned BFI, then turned G-Sync on and they were both working. When restarting my computer I'd have to redo it. Sometimes it takes a couple tries to work.
A: LG never mentioned that BFI and G-Sync should be working together, and most probably it does not work!

P: [email protected] 4:2:0 8bit SDR breaks Dolby Vision playback. Switch screen to that mode in NVCP, turn off tv, turn back on - nothing will play in Dolby Vision.
A: You need to restart TV to get it working again.

P: Dolby Vision content on the CX shows some glow at brightness 50
A: LG has reproduced this and is working a fix, probably via a future firmware.

P: The TV gets "No signal" screen at power ON but the HDMI sources are working just fine.
A: Source is displayed only after a TV power cycle. This is a known bug that it will be fixed soon by a firmware update (April 2020).

P: The CX has some glaring differences in the EDID that is advertised to the HDMI sources (April 2020)
A: the CX is having 4K 100/120Hz 4:2:0 8-bit modes (expected - OK); missing DTS and DTS-HD support (not OK); Max Fixed Rate Link: 3 and 6 Gbps per lane on 3 lanes, 6, 8 and 10 Gbps on 4 lanes (not OK) --- the C9 is advertising a 48Gbps capable HDMI port (12 Gbps on 4 lanes) while the CX is only advertising a 40Gbps port (10 Gbps maximum on 4 lanes); Because of those differences, the CX can't do 4K 120Hz 4:4:4/RGB 12-bit because the HDMI 2.1 FRL speed is limited at 40Gbps (instead of the 48Gbps that is available on the C9). The CX can still do 4K 120Hz 4:2:2 12-bit, 4K 120Hz 4:2:0 12-bit, 1440p 120Hz 4:4:4/RGB 12-bit, 1080p 120Hz 4:4:4/RGB 12-bit, and all other 12-bit modes that don't go over 40Gbps;

P: The CX can't do 120p AV1 streams
A: Apparently, it is true. The new built-in hardware AV1 decoding is limited to a maximum of [email protected], 10bit HDR (no 120p support) - the VP9 decoder is also limited to 60p, only the HEVC content can reach 120p;[/list]

P: The CX/GX TVs do NOT support the HDMI 2.1 DSC (Display Stream Compression) feature
A: True, DSC is not advertised in the EDID (this is also true for the C9). If you think about using DSC to get 4:4:4 chroma (instead of 4:2:0 without DSC, so we don't lose 50% of the chroma resolution) this will result in 62.5% loss of the spatial/chroma detail. In conclusion, use 4:2:2, it's better than DSC - so, in reality, you do not need DSC.


P: The 2020 OLED series still have only a 10/100Mbps Ethernet port?
A: Yes, the 2020 series still has 10/100 Fast Ethernet ports, there are no Gigabit network interfaces on the 2020 series!

P: What is the speed of the Wi-Fi interface?
A: The Wi-Fi interface is connected to the Alpha9 SoC via a USB 2.0 interface so the speed is limited to a maximum of 480Mbps / 24MBps on average. The interface respects the IEEE 802.11ac standard (Wi-Fi 5) - the TV is not Wi-Fi 6 (IEEE 802.11ax) capable;


P: Some TVs have a funny smell that seems to be coming from the speakers in the back. It seems to be like some kind hot or burning chemical or plastic smell. The smell comes immediately after setting it up. All the front+back protection films are removed.
A: The smell is prevalent on 55" units and less on 65/77 units. It is not the usual "new plastic smell" - it is more "caustic" than that. Possibly from the PSU, some owners contacted LG and LG sent a technician to replace the PSU board. Some owners managed to get the whole TV replaced.

P: Some 55/65 CX models were shipped with stands that were destined for the 77" model
A: The long front part is for 55/65 but the heavy part from the stand is for the 77 models and they do not fit together. You need to contact LG and they will send the correct stand for your TV.

Things that future BX owners should know:

Missing features
  • no Face Enhancer
  • no Frequency-based Sharpness Enhancer (BX has only "Sharpness Enhancer")
  • no AI Picture Pro (BX has only "AI Picture")
  • no Perfect Color (BX has only "NanoCell Color")
  • no True Color Accuracy Pro (BX has only "True Color Accuracy" - smaller 3D LUT container)
  • no 4K and 2K playback via USB (BX can play 4K/2K only via HDMI)
  • no AI Sound Pro (BX has only "AI Sound")
  • no 4 full HDMI 2.1 inputs (BX has only 2 HDMI 2.1 inputs + 2 HDMI 2.0 - two ports labeled HDMI IN and two ports labeled HDMI ([email protected]) IN.) - so you will get two HDMI 2.1 ports capable of 10-bit 4K at 120Hz with RGB 4:4:4, and two lower bandwidth ports that max out at 4K/60P with 8-bit RGB 4:4:4.

Limited capabilities
  • Alpha7 gen. 3 SoC (aka M16P3) instead of Alpha9 gen. 3 SoC (aka O20)
  • Lower brightness in HDR/DV (similar to the 2019 B9 model) - needs confirmation
  • HFR limited by the Alpha7 SoC - needs confirmation
  • only two-stage Noise Reduction due to Alpha7 SoC - more image noise with low bandwidth video (Alpha9 has four stages)
  • higher image artifacts due to Alpha7 SoC (especially near-black artifacts and more motion artifacts (flashing, etc.))
  • A smaller 3D LUT container (17x17x17, 4,913 color points) due to Alpha7 SoC (similar to the 2019 B9 model) - this means less accurate 3D LUT calibrations - versus the 33x33x33 LUT system with 35,937 color points of the CX/GX

For me it's only a matter when can I get one of these at a decent price and if I choose a 55" or 65" model.

@dfa973 does the AV1 is really confirmed to the CX series?

Why a 48” ? Is it because it’s a new panel ? New construction ? Less prone to burn in ? Or you just just want the higher PPI ?

No technical reason. Just space constraints.

Vrr + bfi

God's work indeed, thank you OP! I'm going to make a separate thread about VRR and BFI but I'll just throw this in here as well.

It would be great if VRR and BFI could work together. Otherwise, BFI will be almost useless for gaming if VRR has to be sacrificed.

The problem blocking the two features from working together is quite intuitive. With a variable refresh rate the telly doesn't know when the next frame will be displayed. Thus, the telly doesn't know when to start the black frame.

My armchair solution would be for the telly to always start the black frame insertion under 120 Hz timing. This will result in a variable duration for each black frame since the FPS will not always be 120. So be it! This is the compromise to gain the benefits of both features at once.

Would this work or no? Feel free to sound off.
