I bought a Q80T a couple of days ago and have noticed a really annoying issue when using the tv with the combination of HDR and game mode.
I'm fairly certain this is a software bug in the TV since I can reproduce this issue with 100% accuracy, and it happens on the dot at the same moment every time. It's basically on a timer.
Basically when the game is displaying a HDR signal and game mode is enabled, exactly after 6 minutes the brightness of the TV suddenly drops by around 20 (50 -> 30). The value of brightness setting doesn't actually change however. Messing with the brightness setting does not restore the brightness to it's original state, but changing the local dimming setting from standard to low and then back to standard does. Switching game mode off and then back on also fixes the issue, but then it happens again EXACTLY after 6 minutes (I've timed this with a stopwatch).
Has anyone else experienced this issue? Or can someone maybe test this on their TV to see if you can reproduce it?
Exact repro steps on how I can reproduce this 100% of the time on the PS4 Pro:
Some other notes: The PS4 has a screensaver that basically dims the screen if it is idle for a while. This is not the cause of this, this happens even when the console is in active use and the brightness can be restored temporarily by changing the local dimming setting like described above. I have not managed to reproduce this issue with game mode off, so it seems to be related to game mode.
Software version: 1304

Btw, have you noticed difference between standard and high local dimming? Because, at least with games, I ser no difference.

Nah I can't see any difference between standard and high. I use standard generally.

Although, just to clarify. I have only really saw the global dimming happen on HDR game mode with GMP off. It doesn't appear to happen when not using HDR.

It happens outside of Game Mode for me when using Local Dimming set to High

Yup, It also happens in HDR content, including streaming platforms.

Hey guys, I am having the same issue also. For me I notice it only happens while on my PlayStation (using game mode) . If I watch Netflix thru the Netflix app on the tv there is no problem however if I watch Netflix thru the PlayStation game mode enabled it does this awful dimming . I have called the support and had it looked at by a level 2 agent and they remote connected and made some changes but it's still happening . Waiting on another call from them to let them know it's still happening .

Hey man, can you record with a phone/camera your next support session, just in case if it works so we can know what to adjust in the service menu?
