CX: Cannot select 422 in Nvidia colour settings regardless of HDMI cord used

Hi everyone,

Joined the forums after lurking for years to post this. Trying to get some help with a puzzling issue that I can't work out. My apologies if this is an inappropriate place to ask. Mods, feel free to delete if this is the case :) I posted this over on the r/monitor forum on reddit and received a characteristically acerbic response (seriously their are some really combative people that post there for some reason).

I am a CX owner trying to use my OLED as a second monitor for gaming. I have an RTX 3080. When I connect to the tv via HDMI I am only able to select 420 or 444 in colour settings. I am unable to select 422. This is regardless of if I use HDMI 2.0 or HDMI 2.1. My goal is to run a 15 meter HDMI 2.0 cable from my GPU to my television in the loungeroom for the purposes of HDR gaming. This means that I must settle for 422 at 10bit, given the cable's 18gbps data limit. Of course I would happily use 2.1 but the TV is being used in a different room and I need to run a longer HDMI cable. I am willing to shell out a fair bit for the cable, but not the hundreds and hundreds of dollars for a good fibre optic one. Given this, 422 is the best option for me to play between rooms.

So my question is: Why is there no option for 422 when connected to the OLED CX? And further, is there any way to unlock 422 on the OLED CX?

I see other people online saying they have set their CX's to 422 but it doesn't appear in the drop down box for me. I have also tested a shorter HDMI 2.1 cable between my GPU and my TV and it also will not display over 422. As with the 2.0 cable, I can only select 420 or 444.

I should also add that I have tested my PC connected to a different 4k television with the same cords and 422 appears using both 2.1 and 2.0 HDMI, so I can deduce that it is an issue on the CX's end and not an issue with the cords or the GPU.

Please let me know if anything is unclear. If I can sort this issue out it would be saving me from significant frustration and I will be forever in the debt of the AV forums.

Thanks in advance!
