That is pretty low brightness compared to QLED. I was hoping they would have improved it this year.According to Steve Withers AV Forums review it is 128 nits, peak is 660 nits.
Judging by current Nvidia GPUs, you will not be able to use [email protected] + 4:4:4 + 10 bit, but will be limited to 4:4:4 + 8 bit or 4:2:2 + 10 bit. This will mean banding/reduced image quality either way.Thank you for that screen-cap, that is very helpful!
I guess if that is the case, unless I see something stating with data or examples that video down-converted from 12bit to a 10bit panel is noticeably different than a native 10bit source, I do not see what the fuss is. Deceitful for sure, but does not seem to be a reason to revert to a C9.
I readily admit I am a noob to this and may be missing something.
we dont currently know that (and yes 40 gbps is enough bandwidth for [email protected] + 4:4:4 + 10 bit)
Yes we don't, I was basing my assumption off the anecdotal evidence in this thread and my own tests with my 1080Ti that lead me to believe 10 bit in Control Panel is currently only doable in 4:2:2 chroma.we dont currently know that
You're right, fixed that.
Could you tell me how you go that working through Windows 10? Also curious that flatpanelsHD review of the CX said that LG has fixed the issue of PCM audio being limited to 2.0 over eARC so in theory shouldn't 5.1 PCM be enough to do Atmos Atmos decoding over eARC?As for PC, I use extended mode and have 2 HDMI running to both TV and receiver. To get full ALLM and VRR while still outputting proper 7.1 PCM signal along with Dolby Atmos/DTS-X for movies when needed.
is only for CX or for C9 too ?
Confirming the above is correct even while using an AVR that supports eARC with lossless audio. Any video content containing anything beyond a Dolby Digital 5.1 audio track plays with no sound. So this means that regular DTS, DTS-HD and DTS-X in addition to Dolby True HD and Atmos doesn't work. I tested this with the built-in Photos and Video player and PLEX app with Web OS running on my LG CX 77" model.
- 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;
The only way I can get around it is to have my Nvidia Shield running through eARC via my AVR (Sony STR-DN10180 which supports select HDMI 2.1 features such as eARC for lossless audio and ALLM) and that way I can playback DTS, DTS-HD and DTS-X content through in addition to Dolby True HD and Atmos. Both the KODI and PLEX apps on the Shield work just fine (AVR lists the output audio as DTS, DTS-HD, DTS-X, Atmos etc).
My issue now with the complete lack of support for lossless audio on the LG CX is that connecting my PC directly to the TV as opposed to through my AVR so that I can get GSYNC support is that I won't be able to play PC games with Atmos audio which is messed up. Unless there's some way to use the second HDMI port on my GPU to route audio directly to my AVR (not sure how I would go about setting that up in Windows 10)?
Same deal with my Xbox One X as I can't get ALLM and VRR working on my Xbox One X while connected via my Sony STR-DN1080 AVR which by the way supports some HDMI 2.1 features such as eARC and ALLM. So connecting it directly to the LG CX means that I'll get ALLM and VRR but no Atmos thanks to LG's incredibly stupid oversight.
I don't have a 2020 OLED (at least yet, I was possibly eyeing the 48" model) so forgive my ignorance on the matter - but does it not even support plain old uncompressed PCM?My issue now with the complete lack of support for lossless audio on the LG CX
Do you want me to hold you to that?I have nothing against AMD and would gladly support them, but I'm in the high end game and their cards aren't up to it and won't be for a while.
Keep in mind that the Titan RTX is no consumer card from the GeForce line but a very different beast.Here is proof that NVIDIA GPUs can output 10bit to a CX. This is just on the desktop, no HDR game launched.
This works at 2560x1440p120Hz 422 due to HDMI 2.0 bandwidth. Same for 4K60 - Its 4K60 422 10bit.
Well I hope you're right but I'm not holding my breath.Do you want me to hold you to that? /forum/images/smilies/tongue.gif
It's the same on the 1080Ti.Keep in mind that the Titan RTX is no consumer card from the GeForce line but a very different beast.
is this 100% confirmed information ? is this true for both DP and HDMI ?I was referring to 10 bit output with full chroma support. That means either RGB output, or YCbCr 4:4:4 output. This has never been supported for the consumer series (GeForce).
10 bit output is supported for reduced chroma sampling - which means YCbCr below 4:4:4.
Are you referring to 4k support only? I don't have a 4k monitor, but I am able to select 10 bit at 1440p120 full RGB/YCbCr 444 in NVCP.Looks like my post on the 10 bit support in nvidia drivers for GeForce series was not clear enough.

10 bit output is supported for reduced chroma sampling - which means YCbCr below 4:4:4. There is no such thing as reduced chroma sampling with RGB. RGB is always full chroma.
And yes, 10 bit YCbCr 4:2:2 is supported by nvidia drivers, although 4:2:0 is not. But 10 bit YCbCr 4:2:2 has half the chroma information than RGB, which is why it's a big deal. You get more pronounced color-banding with 10 bit YCbCr 4:2:2 than with RGB.
Regarding the "enabling" of 10 bit for OpenGL applications. As far as I know, that 10 bit is not about the encoding of the video card output, but it's about using 10 bit frame buffers by OpenGL applications. This only brings OpenGL applications to parity with DirectX ones, which had 10 bit frame buffers support for years now.
