Baldur's Gate 3 - HDR Optimized Settings (Patreon)

The game DOES USE/APPLY Xbox & Playstation HDR Calibration app settings.

The game has a good HDR implementation by leveraging the console system-level HDR Calibration apps and actually offering an in-game Peak HDR Luminance slider (but not in nits values) which can go up to 4.000 nits on PC, along with providing additional HDR controls.

Currently on PS5 there is the same bug that plagued Jedi: Survivor (which was fixed later) where you need to setup the system level HDR Calibration app last black section to +1 click from zero (and not zero as suggested) in order to avoid all blacks glitching, providing a bugged picture of the game. Hopefully a fix for this PS5 issue will be released in the near future as well. --> FIXED FROM PATCH 1.200.003 (No more need to change PS5 HDR Calibration)

Also the black levels seems a bit raised in HDR compared to SDR, but let's see how to fix this below:

On PC follow the instructions on the first HDR Calibration slider by clicking right 1-by-1 until the image totally disappears, then do -1 Click back and click Next.

This will be very accurate and will exactly correspond to what Tone Mapping you're currently using/preferring (e.g. 800 nits for all LG OLEDs except G2 at 1.000 nits and G3 at 1.500 nits when using HGIG, 4.000 nits when using DTM).

In all cases, in the next section change Brightness to 201 and Contrast to 1.25

This will fix the black level raise along with providing a proper/balanced HDR range to colors and luminance.

Enjoy ;)
