A couple of possible bugs on Nvidia's beta firmware 440.52:


1. No "Integer Scaling" available as a scaling mode on NVCP (exclusive to RTX; available on stable fw);
2. Tearing at the top of the screen when scrolling up or down on Firefox running in full screen (G-Sync enabled; VRR on Windows on/off didn't make a difference).

I have no idea how to calculate the values for "OC'ed" refresh rates (66/126Hz).
Blanking is just the difference between your active pixels and your total pixels. Blanking is made up of the front porch plus the sync width on the top and left and the back porch on the bottom and right. The back porch is calculated automatically on that custom resolution screen. These numbers use to determine the centering of the image on CRT displays. Now they just have to fit between the active and total pixels and not be too small that the TV can't sync.

As you reduce the total pixels to use less bandwidth you may need to reduce the front porch if the back porch becomes to small. Just subtract the active pixels, front porch and sync width from the total to see how big the back porch is.

How do you know when you need to reduce the total pixels? You calculate the bandwidth and keep it under 18Gbps. To calculate it you take the pixel clock and multiply it by how many bits per pixel are used (see below). Then divide by 8 and multiply by 10 to get the encoded bandwidth. So the one from the screenshot is 69.2453MHz * 24 BPP/ 8 * 10 = 2.077Gbps.

Bits Per Pixel (BPP):
4:2:0 8-bit = 12
4:2:0 10-bit = 15
4:2:0 12-bit = 18
4:2:2 8-bit = 24
4:2:2 10-bit = 24
4:2:2 12-bit = 24
4:4:4 8-bit = 24
4:4:4 10-bit = 30
4:4:4 12-bit = 36
RGB 8-bit = 24
RGB 10-bit = 30
RGB 12-bit = 36

The refresh rate just changes the pixel clock.

Note: Ignore the BPP on the custom resolution screen. That's the video buffer BPP and not the HDMI BPP.

Note 2: Pixel clock is usually horizontal total * vertical total * refresh rate

I don’t think the lagom test is a good test for this kind of issue especially for hdr because even when we turn hdr on in windows, the lagom website is not in hdr. Correct me if I’m wrong but we may need a true hdr test video.

Could more people confirm that instant game response now work on pc with the latest nvidia driver, as in we can have get low input lag for all picture modes? That will be great news for people who can’t get their set calibrated as cinema/techniclor mode are more color accurate vs game mode.

When games don't support HGIG, I feel like the picture looks too dim for my tastes...to the point that you lose detail in dark scenes compared to turning DTM to 'on'.
You should be switching between "off" and "HGIG" not DTM and HGIG as there will always be a difference

What would lead you to believe that 4k 120hz isn't capable on a set that supports HDMI 2.1?

Well within spec so no reason for it not to. To continually post about your long returned set just because you bought it knowing there's no HDMI 2.1 sources out yet is kind of silly.

Definitely do a panel replacement or wait for it to come back under extended warranty and cash out.

It will always come back

I got the latest LG update and I installed the Nvidia Beta drivers 440.52 I went to the nvidia control panel and enabled G-Sync played Gears5 and GTA V and G-Sync does not work I had my settings at 4k with V-Sync off and it was plenty of screen tearing don't believe these people claiming it works they're lying or placebo effect and I have a MSI Gaming X Trio 2080ti and a i9 9900k G-Sync didn't work which is probably why Nivida haven't release G-Sync support officially

You need a source that support HDMI 2.1 genius you should've already known this but once the 3000 series Nvidia cards drop they'll be HDMI 2.1 next time educate yourself google is your friend

Have a look at this video, and pay attention as the game transitions between gameplay and the map. Total black on 436.51, a grey blotchy mess on the 440 drivers.

https://www.youtube.com/watch?v=lAd9rOCsMmo

Please see if you can reproduce this, and if you can, please report it to Nvidia.

I really don't want HDR to be broken when the Gsync driver finally arrives!

Edit: Tested some more. Driver 440.97. All tests are with Output Dynamic range set to Limited, and TV set to Low Black Level. HDR enabled in Windows:

4:2:2 10 and 12-bit: Black is grey
4:4:4 8 bit: Black is grey
RGB 8-bit: Black is black
4:2:2 8-bit: Black is black
4:2:0 8 and 12-bit: Black is black
Can confirm that 440.97 and the beta driver have messed up my blacks in HDR on my c9.

Based on comparisons with the youtube app, the background should be pure black when you run these black clipping videos in windows in HDR. However, with the new drivers at 50 brightness, the background is grey not black, which is wrong.
-SDR:
-HDR:

To get pure black when in HDR you now have to set brightness to 47 instead of 50. However, after doing so you cant see all rows before the pure black row in the HDR chart, unlike the native youtube app.

Hence, in summary, the latest Nvidia drivers have totally messed up the HDR black levels on our sets in windows and we now have lost lots of near-black detail. This produces a dramatically inferior image compared to what we had before (and compare to what we have on the consoles and the native apps). This is a much much bigger issue for us compared to the banding on the pc input (assuming Nvidia does not fix this in the next driver).

Everybody should report this driver issue here: https://surveys.nvidia.com/index.jsp...f07694a40f8ac6

Would you mind toning it down a bit? Calling people liars and condescendingly "geniuses" isn't really appropriate. We're all here to talk about our TVs, not spring at each other's throats.

Yeah, I learned after doing the testing that it's not a very accurate measurement for HDR. This is what EvilBoris (HDTV's resident HDR expert) had to say about that on another forum:

I don’t think you can use the same test pattern in SDR and HDR as the values mean entirely different things and although firefox might function in HDR, it will likely treat that image as SDR, so then falls victim to Window10’s SDR to HDR conversion. Ideally you need to find a greyscale ramp for HDR to properly evaluate the HDR banding.


My SDR results still stand, however.

It doesn't work on the latest driver (440.97), only on the beta one (440.52), as I mentioned. Latest Game Ready driver doesn't have support for G-Sync on the C9.


You also can't change any of the extra picture settings after Instant Game Response is engaged. I believe you need to adjust those settings beforehand, so that they stick when VRR activates.

G-Sync definitely works on the C9 with 440.52. Give these two articles a read so you can have a better understanding of how it works and what settings need to be changed:

Haven't tested HDR yet, but black levels are normal in SDR with both 440.52 and 440.97 here. Is it affecting SDR content as well for you guys?

Sorry it is only affecting HDR not SDR. Everything looks correct with brightness at 50 in SDR and I have now clarified this in my previous post.


Would be nice if you could test the hdr black clipping video with HDR enabled on your set, does it look identical to the same video running at HDR in the native youtube video app? (in other words, the background is pure black and you should see all bars before the pure black bar)? if any of the two black clipping videos I have posted show a grey background instead of a pure black background, then you are also affected by this issue. I would assume that everybody who has a c9 and the latest driver installed has their black levels messed up now.

Also, for those with GPUs that only have one HDMI output and are having issues connecting their cards through an AVR, here's a link to my workaround. Full quote in the spoiler tag:


Spoiler!
OK, nice to know I am not crazy and that RGB full/limited was causing issues in some content with PC mode. After switching to YCbCr444 8bpc and setting the TV to HDMI Level Limited, I get a great picture in all content. Is there a reason to still switch out of PC mode for HDR movies if you set YCbCr444 8bpc?

Has anyone confirmed that GSYNC/VRR is working through a receiver yet? I am no longer using the beta drivers.

EDIT: I can however confirm that 4K66Hz and 1440p120hz passthrough my Denon X7200WA just fine with custom resolution. Really hoping VRR also can passthrough.

(in other words, the background is pure black and you should see all bars before the pure black bar)? if any of the two black clipping videos I have posted show a grey background instead of a pure black background, then you are also affected by this issue. I would assume that everybody who has a c9 and the latest driver installed has their black levels messed up now.
Tested HDR with brightness set to 50 and instantly noticed the gray background, as I use Dark Mode in Windows. Tuning it down to 47 "fixes" it, but on the video you linked, reference black becomes 72, instead of 64, as it should, so there's definitely some clipping going on.

Is there a reason to still switch out of PC mode for HDR movies if you set YCbCr444 8bpc?

Has anyone confirmed that GSYNC/VRR is working through a receiver yet? I am no longer using the beta drivers.

EDIT: I can however confirm that 4K66Hz and 1440p120hz passthrough my Denon X7200WA just fine. Surprising.
Well, EvilBoris says that HDR needs at least 10-bit to work properly, so he recommends switching to YCbCr422, either 10 or 12bpc (our panels are 10-bit, so it really doesn't matter, but some say that 12bpc is better, regardless). To quote him directly:

Well 10bit data is 4x the amount of data as 8bit

So let’s say it’s 16:16:16 in 10bit


Even with 2 of those being halved You will have 16:8:8

So 4:4:4 vs 16:8:8

This is not at all how it works I will add, but it illustrates that there is significantly more data passing through in 10bit YUV 4:2:2 vs 8bit 4:4:4

This is why 10bit it is required for HDR.

If you are not using HDR , then you aren’t pushing as much data through, so you are better off going for the highest quality 8bit output you can


And after I asked for confirmation that 8-bit 4:4:4 is better for SDR (movies and games), and 10-bit (or 12-bit) 4:2:2 is recommended for HDR:

Yeah exactly.

Worth noting that it’s not uncommon for TVs to treat a Pc input incorrectly for HDR, sometimes you are better letting the TV think it’s a game console.

As for G-Sync/VRR, it should only work with a direct connection between the source and the TV. 4K and other non-standard resolutions work with different refresh rates depending on the AVR's firmware. You can edit their EDID (when they're viewed as a display by Windows) using CRU, to add what's not already not available.

Hello everyone, I'm new to this forum,
I've read a hundred pages in this thread, and got some help on how to better use my wonderful C9, but I still got one major problem,

My gaming computer doesn't show 1440p resolution, I have a Sapphire R9 390 Nitro+, which is an old graphic card, with HDMI 1.4 (I think), limited to 1440p 60Hz or 4K 30Hz, using High Speed HDMI, with Ethernet and without (tried 3 cables) and tried also a Display port to HDMI (active) capable of 4K 60Hz but also not working on my TV, my computer is configured as a PC on HDMI 1.

Got no issue with 4K 30Hz but no other resolution above 1080p has 60Hz, and 1440p isn't listed at all, what ever I changed, disabled HDR, changed YCB444, 422 (don't know real names), disabled all options in AMD Settings, nothing worked, so for now I'm limited to 1080p 120Hz, and that is very fast and fluid,

Note that I've also a 4K monitor from Samsung and everything is working perfectly, 1440p 60Hz over HDMI, and 4K 60hz over Display port to Display port, and 4K 60Hz over Display port to HDMI cable,

I also managed to display 1440p 60Hz by adding this resolution manually to AMD Settings, but I've got an unplayable experience IG, image stutter as hell, so I gave up,

Now I'm interested to change my graphic card, it's time as my R9 390 is really useless with its HDMI 1.4, I'm interested on RX 5700 XT, and I wonder if someone tested it on 2019 Oled LG TVs, I don't want to buy an expensive card that will not profit of 1440p 60Hz or 120Hz, as my R9 390 is fully compatible with this resolution, but doesn't even show it on my TV, so I'm afraid that other new cards doesn't show 1440p also.

Note also that I've got the latest update 4.70.05, and HDMI ULTRA HD Deep color is enabled, nothing changed

Sorry for my mistakes, english is my third language,
Thank you.

Here's a link: https://www.mediafire.com/file/f38mk...40.52.zip/file


Just unzip it and run Setup.exe.

Sorry... my bad, you are 100% correct - it had flicked back to RGB 8-bit and I didn't clock it (pun intended! lol). Interesting about CRU, will be good to hear how that goes (I can't seem to get on with CRU for some reason... I think it's because it has too many options for my lizard brain)

Confirmed... same for me.

4:2:2 10 and 12-bit: Black is grey
4:4:4 8 bit: Black is grey
RGB 8-bit: Black is black
4:2:2 8-bit: Black is black
4:2:0 8 and 12-bit: Black is black
Appreciate the follow up - good info! Fingers crossed it's sorted in the next release.

That is exactly what I am seeing. brightness 47 in HDR is closest to being correct now, but still clip a lot of details that were visible in older drivers (and in the youtube app) Please report this to Nvidia here: https://docs.google.com/forms/d/e/1F...?usp=send_form

Since we now have 3-4 independent measures showing the same result, I assume all C9s are affected and probably also many other displays as well.

The local electronics store has a new panel and is ready to replace mine. I’ll lose the calibration that I currently have tho. I think I’m leaning to have it replaced.

Is there any way to get 5.1 Sound atm when connecting the PC directly to the C9 and using eARC?

Maybe with some extra device? For example a soundcard which somehow decodes PCM into some sort of DD+ 5.1 ? Sorry i have no clue about sound.

Yes you are correct. I am limiting my fps to 57 and 117 either using RTSS or in game fps limiter.

I didn't at first when I tried Destiny 2 at 4k and it was ridiculous tearing. After limiting to 57 it was butter smooth. However I felt that given the low input lag, 120 (117) just felt so much nicer. There is of course a noticeable loss is visual clarity.

Hard8times - if you are unsure if G-Sync is working, you can try the Nvidia pendulum demo.

So far I think the implementation of G-Sync compatibility is impressive.

Its curious Nvidia didn't include it in its recent driver. LG released the new firmware a day before and the timing, along with articles stating October for both firmware and driver to drop, would suggest it may have been planned but pulled for some reason.

I expect and hope it is included in the Red Dead 2 game ready drivers. If so we are in for a treat.

yeah i had the same thing.

I think our 2080ti's don't even need gsync.


But i also read you can enable g-sync from the windows display settings as well as the nvcpanel. try the windows setting. i uninstalled already, because my windowed games like path of exile were choppy as all hell, until i frame rate limited it to 57fps with rivatuner. Even then it wasn't as smooth as just plain old vsync.

Also the Nvidia Pendulum G-sync test demo, would probably be the best way to test.

4K 120hz is impossible until nvidia release hdmi2.1 cards, or LG hack the tv like Samsung to do it.

Hello,Question to all series 9 owners. How much better is the 1080i upscaling (HD cable) compared to the 7 series? One major fault I have with the 7 series is the cable upscaling.

Regards
Jeff
