Here's our recommended best settings for the PG32UCDM3 (aka PG32UCDM Gen 3). Review available here: https://tftcentral.co.uk/reviews/asus-rog-swift-pg32ucdm3
General settings
Power setting = Performance mode
DisplayPort stream = leave this on DP 2.1 (20G) unless you have specific issues with older cards or something (shouldn't do)
OLED Care options = leave as many turned on as possible, only disable those that cause you problems
Neo Proximity Sensor = worth turning this on and setting customised viewing position
SDR setup desktop and general
Game Visual Preset mode = User
Uniform brightness = On
Brightness = 37 (for 120 nits) but set this at whatever you find appropriate and comfortable for your viewing environment
Contrast = 80
Gamma = 2.2
Colour temp = User
RGB levels = 98, 100, 99
Colour space = Wide gamut
Blue light filter = Off
Calibrated ICC profile attached below to pair with the above settings and operation in the wide gamut mode. ICC profile will clamp colour space back to sRGB for use in colour aware applications
SDR setup - sRGB emulation
If you want to operate with a restricted sRGB gamut at all times for SDR content we would recommend switching to the Game Visual > sRGB Cal preset mode. do not use the ICC profile with this though. Most other settings are then locked, but you can change brightness to whatever you feel is comfortable.
Gaming settings
Shadow boost = experiment for darker games. Dynamic mode had most impact
Variable refresh rate = On (for G-sync / FreeSync)
HDR settings
HDR format = leave this on HDR10 for PC inputs, or switch it to Dolby Vision for any specific DV compatible devices (e.g. Xbox Series X) if needed
HDR mode = Gaming HDR (for PC), or Console HDR (consoles)
Adjustable HDR = On
Brightness = 100
Contrast = 80
Uniform brightness = Off
Colour temp = 6500K
Dynamic brightness boost (only available if using Console HDR mode) = On
