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

Dimming bug has been resolved and fixed. Please close thread. This has been spoken with developers and no longer an issue.

People who are saying there is still an issue. Please update your firmware to the latest one.

Also for the game mode?

YES

But the local dimming in game mode with GMP OFF is still not working perfectly as it was before update 1304!

That is not true. I was personally given firmware 1402 and tested myself. No issues. Deeper blacks, less banding, better picture quality and no dimming issues. There are no issues with latest firmware.

What about ghosting issues?

Well..there are horizontal lines without gmp and vrr does not work right in games like ori and the will of the wisps on xb1x..looks bad

No, the local dimming with GMP OFF does not perform as well as it does with GMP ON. So it was NOT corrected, at least in the firmware that YOU provided.

This Suriya is not the “real” Suriya. It’s a troll hah. So ignore them. The real Suriya has no accent above the “i”.
