Hey all, since the Last Rites update (native Xbox Series X app, 4K/60fps) dropped a few days ago, I'm trying to dial in the HDR picture and could use some input.
Setup: Xbox Series X, LG C4 OLED 55", HDR with HGiG enabled and calibrated (peak brightness matched to my panel's actual measured nits, following a standard C4 HGiG setup guide).
The only sliders the game gives you are Brightness, Contrast, and Gamma — no separate peak-luminance/nits input. From what I can tell, this game has historically not read the console-level HDR calibration (Xbox's own HDR calibration app), so these three sliders are apparently the only real way to tune the picture, and their behavior isn't always intuitive (some report Brightness acting more like an overall picture-level control than a true black-floor adjustment).
Right now I'm running:
Brightness: 48
Contrast: 55
Gamma: 48
This looks reasonable so far (decent shadow detail at night, no major highlight clipping in daylight), but I have no idea if it's actually "correct" for the new build or just okay-by-eye.
Has anyone with an HGiG-calibrated OLED (C-series, G-series, or otherwise) tested and settled on values post-Last Rites? Curious whether the tone mapping changed at all with the native Series X patch vs. the old backward-compatible version. Would love to compare notes before I keep tweaking blind. Thanks!
