    Hi mate, you need to disable the HDMI audio in the nvcp. I have the same TV and the screen would constantly flash from desktop to a black screen until I disabled the audio.
    I would actually roll back the driver for now as the HDR detection is currently broke (if your using windows 10 1703).

    Because it's rolling out now and everyone is updating to it. Basically back in the day we used to have Service Pack 1, Service Pack 2, etc. Now we have Anniversary Update (RS1), Creators Update (RS2), etc.

    Always best to keep your Windows up to date. But if you don't want to face any of these issues, hold back for a couple of weeks while they get fixed. However updating and finding out what issues you might have, can get them fixed faster if they're reported.

    This TV flickering you speak of happens with my 1080 Amp as well and it's been happening since RS1. For me anything over 1080p on my LG 4k with full RGB enabled causes flickering, desktop and in game.

    To stop the flickering I need to power cycle the TV for 6 to 8 seconds, I'll hear the windows device disconnect sound, any less than that and it'll just keep flickering after powering the TV back up. The freeze issue only happens every few days. Just pressing the power button once to let Windows shutdown and then power cycling after it's shutdown fixes it for me temporarily. To be fair this also used to happen when I would downsample/VSR/DSR with my AMD 290x from 1440p on Windows 8.1 and early builds of Win 10 when I still used the card.


    I keep checking the forums for a fix but nothing has gotten fixed. Switching HDR off and setting the color range to limited stops all flickering and freezing in any resolution. I assume this is still an issue because not many PC gamers game on a TV and this is not an issue with true 60hz 4k monitors as far as I can tell but I do not own a monitor over 1080p so I cannot test this.

    I deal with the power cycling because HDR/Full RGB/Deep Color and 4K are totally worth the trouble.

    Think you guys are getting confused as to what is my issue.....

    I will try to make it a little more clear:

    The problem is when i power on the tv, i hear the windows device connect sound, then i sometimes or sometimes not get a pciture but at the same time causes awfull stuttering from my system, and the mouse judders then freezes then judders and freezes at the same time im stuck in a windows device connected and reconnected loop until i get a BSOD VIDEO_TDR error..... from windows 10......

    hope that makes it more clear.

    I'm getting the same freeze with my Titan X (Maxwell) SLI + OLED B6

    Nvidia now defaults the settings to 12bit YCbCr 422 which looks rank awful. I managed to change it all back to 8bit Full RGB but then I couldn't get Shadow Warrior 2 to work with HDR enabled.

    Now i'm getting a lot of BSOD with: video tdr failure nvlddmkm.sys problems.

    I'm going to try completely disconnecting my X34a primary desktop monitor to see if that cures it.

    Well, that is a limitation of HDMI 2.0, you can't have it all at once but only:

    4k@60Hz@4:4:4@8bit
    4k@60Hz@4:2:2@10bit
    4k@30Hz@4:4:4@10bit
    2k@60Hz@4:4:4@10bit

    You need DP1.4+HBM3 or HDMI 2.1 (neither is available on TVs yet) for 4k@60Hz@4:4:4@10bit (and even DP1.4 can't do 4k@120Hz@4:4:4@10bit or 4k@60Hz@4:4:4@12bit without lossy on-link compression, though I am not sure about the latter in practice).

    (Note that 12bit is usually available as well in most of the cases listed above with 10bit but not when it's marked with 8bit top: you either run out of bandwidth before reaching 10bit or you cut your bandwidth down a lot with the other parameters, so when you make room for 10 bit, 12 bit will usually fit too. However, that doesn't matter so much since most HDR material is 10bit now and you probably care a lot more about 60 vs 30 Hz and/or 4:4:4 vs 4:2:2 than you would care about 10 vs 12 bit anyway...)

    Although... since most VGA cards will have a really hard time producing stable >30fps in modern games in 4k HDR mode, the 30Hz display mode might be considered as a viable compromise. (I personally hate it but most people never get more on game consoles and they don't even complain.)

    I'm well aware of the limitations of HDMI 2.0

    The big point is that prior to these drivers, I had no issues with my B6 OLED. There was no driver crashes with the TV connected, It looked great, Shadow Warrior 2 ran fine with HDR etc

    Now I have to physically disconnect the HDMI cable just to get past the windows 10 login screen.

    There is an issue here.

    Even though they use an Xbox One S (locked-down Windows 10 PC) as an example, this should apply to PC use as well.

    how-to-get-hdr10-enabled-on-the-lg-b6-oled-4k-hdr-smart-tv-oled65b6p-and-work-with-the-xbox-one-s


    But what Janos666 said is pretty much truth. 4k@60hz 4:4:4 Full RGB (without HDR) is 17.82gbps out of the 18gbps HDMI 2.0 provides and LG TV's allow this by enabling 'Ultra HD deep color' in the 'general' section of the menu.

    If you have audio enabled over the same link, it will flicker due to lack of bandwidth, which disabling it is the trade-off for using 4k@60hz 4:4:4 Full RGB.

    This is why I won't buy a 4k TV till HDMI 2.1 is out, since I prefer using an HDMI audio receiver with my PC. Everyone jumped on the HDR bandwagon too soon.

    Where did you read this? it is incorrect.

    full rgb at 4k 60 is 25-27Gb/s

    UHD is 4:2:0, with optional 10bit / HDR.


    LG TV's use color compression, it's a hack and it adds to panel lag.

    I just set this up with a B6 and can confirm I had strange 'snow' on my screen until I disabled audio to the TV.

    I also use HDMI for audio out to a receiver -- from an Auzentech HTHD -- however you can also simply use another HDMI port on your NV card to your receiver for audio. Alternatively, you can use a DP to HDMI from the card for video and the HDMI port for audio.

    I get the snow effect as well if the TV isn't flickering already at 4k full rgb. I have not tried disabling hdmi audio though. If I bought a displayport to hdmi adapter would this issue go away?

    It might be the quality of your HDMI cable if it persists when you disable the audio. An adapter wouldn't solve it.

    I did that for a bit when we were remodeling my parent's basement and they bought a new LG 55UH6150 4k TV (which of course I played around with... :nerd: ).

    But what I don't like is having the video card running two different-sized viewports (my current receiver only passes up to 1080p. So going to replace that too when I get a 4k HDMI 2.1 TV) when gaming as it messes with things like v-sync and UI sizing.

    Just got home from work and I can confirm disabling hdmi audio through the nvidia control panel has cleared up the snowy signal and desktop flashing when running 4k 60hz full rgb. It must be a bandwidth issue. Luckily for me I use another audio source other than hdmi so this works for the time being.

    I think the lack of 4k@60Hz@4:4:4@10-bit is reason enough to skip all displays limited by HDMI 2.0
    I would also prefer 12-bit for Rec2020 with HDR because those "precious bits" now cover a lot bigger gamut (both in terms of chroma and luma), hence 10-bit is not an improvement at all but a pure necessity (banding could be way too obvious at 8-bit in certain content), you need 12-bit to really improve on the perceived gradation precision (compared to the "retro gold standard" 8-bit which should have been replaced by 10-bit in the FullHD era...).
