When using Game Optimizer + HGiG, the Windows 11 HDR Calibration Tool shows a peak brightness of 790 nits. However, when using FMM + DTM Off with all sliders set to 100, the peak brightness shows 600+ nits in the calibration tool.

AVS Forum recommends using FMM + DTM Off since it is more accurate.

Should I use Game Optimizer + HGiG, or use FMM + DTM Off but set the calibration tool to 790 nits (even though the test pattern disappears at 600+ nits)?

Any thoughts?

I got a small chip on my windshield, anyone knows a repairshop. Thank you in advance.
