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

This could be my last Samung product. Before my new 65" Q80T, two of my last 3 smartphone are from Samsung, I have two 40" TV (one is 3D), my blu-ray player is Samsung and even my sound bar is from Samsung.
And now, I have to wait months, maybe years to a new update for the firmware. Painful.

No they'll never reply until if you make anything against forum rules lol. They're only watching who is breaking forum rules ect. Not reporting anything from samsung to users or user to samsung. Very bad

I made a post on the Samsung reddit sub. Please go and upvote/comment that you’re experiencing the same problem. Trying to post on all avenues so someone will finally fix this issue.

This would even further help Samsung completely nail down the problem. There’s no reason that they shouldn’t be able to fix it now with all the information that has been given to them.
