I am going crazy as I can't get my PS5 to output to 1080p/120hz (even when I have Borderlands 3 playing in performance mode in the game itself). I have been googling this issue and I've performed a lot of what was suggested and my "possible output information" (on the PS5) doesn't mention 120. I'm using a HDMI 2.1 cable and I also tried the cable that came with the PS5.
- C8 - Up-to-date firmware wise, game mode, HDMI deep color, changed input to PC to see if that did anything
- PS5 - game preset to performance, tried automatic (for all settings) and 1080p locked in the screen settings, turned off HDR, RGB to full
