hey, since you have RTX 3080 + a good HDMI 2.1 cable - can you clarify some things please:So a couple things from someone with a 3080FE using this HDM 2.1 cable.
1440p 120hz is great. 4k 120hz will push a 3080FE into 72c BRRR mode even on a old game like ffxiv.
When setting up 120hz on a Nvidia 3000 series card use the nvidia control panel and scroll down till you see "PC"
3840x2160. I had to use my second monitor to set this cause my TV would freak out after turning on 120hz mode in the external input settings.
I don't mess with HDR much but its turned on in doom eternal and that runs fine at 4k 120hz??
1) Is 4K-120-4:4:4 (with and without HDR) - blurry/fuzzy for you or not ? put Windows DPI scaling at 100% and then compare the ~sharpness/clarity of desktop icons at 4K-120 vs same at 4K-60 (it should be identical and crystal clear, but it may not be with Sony implementation)
2) How does [email protected]@4:4:4 look - better than [email protected] ? Does it have any unusual fuzziness on desktop text/icons ? Or everything is good and sharp ?
3) Same as the first but for 1440p - can you compare [email protected] vs [email protected] and see if there is a difference in clarity/sharpness for desktop text/icons
Maybe take photos of the desktop icons as you test, if you can.
