[SOLVED] I finally got my hands on a 3090, after installing, I’m having a hard time getting 4K 120hz to work.

Lg 65” b9 oled. I9 9900k, 750w psu, 32g ram @ 3200, 3090.

When I go into the resolution settings, under the “pc” resolutions, only a handful of low resolutions are available. Ultra hd resolutions are all there, but it is to my understanding in order to get 4K 120, it has to be on one of these pc resolutions. I have uninstalled old 2080ti drivers and installed newest drivers from scratch. Another symptom, when I enable hdr on my tv, I lose my signal. Never had any issues with the 2080ti. Please help!!!

If I remember correctly, that is related to this: https://www.pcgamer.com/firmware-fix-makes-lgs-oled-tvs-play-nicer-with-rtx-3000-cards/
That screen needs a firmware update. Check the support page downloads for said update, if available: https://www.lg.com/us/support/softw...US&category=CT10000018&subcategory=CT30017665
