2022 frame 75 inch and 55 inch having the same issue.
When the TV is in art mode and is turned back on from a CEC event (Chromecast or Xbox turning on) the brightness does not actually show to reflect the TV brightness settings. Every time the TV turns on I have to go into the picture setup and adjust the brightness settings by 1 value in any direction and they'll return to what they are actually set to. This is hard to describe, but if brightness is at 20 after turning on from art mode in a dark room, the TV appears to be at what I could best describe as actually 0, when the brightness is adjusted even by 1 it snaps back to what the value is actually set to. This means that whenever I turn my TV on, I need to open the brightness settings and turn the brightness down 1 and then back up 1 and it will be at the actual value set on the TV. This is newly broken with the 1602 firmware. Do I have something configured wrong or is this just another poorly tested firmware update?
How is everyone else coping with this? Just putting up with it, or have you found a workaround? It doesn’t seem to happen *every* time for me (still most of the time though), but I haven’t been able to discern anything I’m doing differently when it happens vs not.
I’m still putting up with it. Since a software update was pushed out several months ago the frequency has reduced, but it still occurs (excessive brightness reduction when switching out of art mode) at least once per week.
