    When you say a few seconds do you just mean when the game is booting up? Because for me its happening in game, can drop in and out constantly for about 30 seconds, then might be fine for a few minutes then could start happening again for a few seconds or even a few minutes. Its really random when it happens.

    Also, do you use PC or game console as the HDMI input on the TV? I have a C9 fwiw

    Oh, do not see that. When going into windows see notification and usually when firing up a game for first time into fullscreen. Do not see message popping up ingame, that would wind me up if it did that. Yes this is with a C9 / latest update and 3090.

    i cant enable 10 bit rgb anyways. only 8 bit full rgb. any of the other options under 10 bit have to have limited Dynamic range.

    Same here, never in game.

    @LukieBoy007
    I use the console symbol on HDMI 4

    It's worth trying different HDMI ports because my HDMI 1 had issues.

    Yep thats because you need a RTX30 series card with HDMI2.1 for 10 bit full RGB

    Yeah its in game, tried GTA yesterday and would be constantly flickering in and out. When you say latest firmware is this an OTA one or one manually installed? I've got the latest OTA update on the TV

    It isn't.

    Unless you force 8-bit color, limited RGB, and use 4:2:0 chroma subsampling and make sure HDR is off.

    Then it might work but the image is compromised anyway.

    You’re welcome. Only dabbled with 120Hz a couple of times but the Doom games are slick at 120FPS on my 3090FE.

    Not many other games I play will run anywhere near 120FPS though unfortunately, least not at 4K.

    Yeah, it'll be mainly older games.

    Doom Eternal just happens to run amazingly

    Forza Horizon 4 is another that will run at pretty much extreme settings at 4k/120hz, as long as you keep the MSAA at 4x or lower.

    This issue still occurs

    c9 on latest firmware and 3090 on latest drivers

    Enabling Gsync at any resolution or any framerate results in raised gamma and flickering

    Not on my C9.

    Use a different HDMI port on the TV as that was my issue

    This Cable:

    These settings:

    I swapped out my 2080Ti for the 3090 and used the same HDMI port on the TV, which was HDMI 1 and it was set on the TV with the 'PC' symbol. This is where the issues came from (see earlier post in the thread) where I had flickering.

    When I tried HDMI 4 which was set to 'Console' it worked fine with 4k/120hz/4:4:4/HDR on and G-sync enabled, with no issues at all.
