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

But neither the US version of the firmware, which many installed officially, fix the localdimming in game mode (out GMP). Only the bug has been solved.

It’s like Samsung has never built a tv before. Hope you are wrong and they know what they are doing.

Reports on Youtube show that the US update does solve the local dimming issue.
Make sure to check the comments.

The new firmware really solves the localdimming bug that darkened the image after 6 min. However, we are talking about the effectiveness of localdimming in game mode, which was drastically reduced in firmware 1304, and which was not fixed in this new one.

Oh I see, that's bad.
I still have one week to decide if I'm going to keep this TV and I really don't know what to do.
If Samsung would clearly state that they're going to fix all issues, it'd be a no brainer.
But I rather take the chance of burn-in OLED than this mess.

if i were you i would keep the tv. I don't dare to do it because of burn-in ... personally I am satisfied with the local dimming. I'm just waiting for the update. does anyone happen to know how to switch off automatic update of the TV via the router? after the 1402 update I don't want to receive any more updates.
