Of course, Im on a newer version of Windows 11 with an older driver Nvidia 566.36 and all the usual TV stuff is turned off, and on Static Tone Mapping. Game Mode On, 50/48/10/25/G2, Warm1, Static, ST.2084 0, SHADOW 0, AUTO Colorspace and High Peak Brightness. the TV Firmware is on v2024 right now though, so I assume wither Windows or the firmware has changed something, but Im sure I have hit 1800 on this firmware before, but i have been running SRD most of the time. Just curious.

UPDATE: Like some have said regarding tone mapping, Ive always had both HDR10+ Gaming and HGiG on Basic while I calibrate with the Windows tool, even when I got the 1800/2000 and now at 1400. Maybe the Calibration tool or Windows has changed things. I will retest with HDR Gaming off and also test on PS5 Pro and report back.
