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

Hi Guys
My journey so far with this TV Q95T 65 inch is that i got my 3 Panel replaced yesterday due to several issues.
First Panel had a clicking sound on startup and 3 dead pixels middle of the screen.
Second Panel had horrible DSE and 4 dead pixels lower right corner and wifi issues
Third Panel that i got now have less DSE and beacuse its a lottery how bad Panel you will get regarding this issue im gonna keep this TV. No dead pixels.
All Panels where manufactured in Hungary. Its seem that they dont have any quality check before they send out these "bad" panels.

Just bought the Q90T in the Netherlands , and waiting for it to arrive. Now I wonder if I made the right choice. If you turn on Game Motion Plus, will the dimming bug occur as well? If not, why would you turn this off? What happens if you use VRR? Lastly, when talking game mode Vs movie mode, will it happen in both modes? If not playing shooters, is moving mode also fine from an MS input lag perspective? Sorry for so many question, but this treat scared me. 😞

Do yourself a favor and return the tv immediately.

"obtain a 75" Q90T for less than a 65" I guess it was a shady store and got a unit which has been already returned. Here TvReus and El-Vidas has 65Q90Ts 200€ less than the market...it's always suspicious. In an another forum someone found they have the same return address.
