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

Without VRR it's the same as before I turned the TV off. With VRR, it's so dark that games are not playable. Changing any off the settings doesn't help. Samsung's software is very bad.

Looking to purchase this tv
If I don’t use vrr it would look bright with good black levels in game mode??

Yes, most likely. At least until you update to the next software.

Sorry, I tried making a video earlier but I don't have a camera that can effectively capture the TV Screen.
I have to turn on all the "enhancement" features to get the screen bright enough in game mode. I'm not sure how much impact these features have on input latency. VRR is the biggest reason I bought the TV, so I can eliminate more input lag. But right now it's unusable.

So with the new firmware. What’s everyone’s new settings for HDR/SDR shows, movies, and gaming?
