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

Nope. Not on mine anyway.

Frmware 2010.3 should be available soon for 2020 models and the changelog states that dimming bug is fixed in game mode, though I did see a post on German community that someone who installed it still has issues.
I do not work for Samsung or make Samsung Products but provide independent advice and valuable contributions.

Hi,
I am Looking for Q95T information about HDR and Game mode problem . Also, Local Dimming Problem and 120hz PWM Problem
1. Under Game mode situation, the Q95T still have low PWM problem(horrible 120hz)?
2. Does Q95T firmware fixed HDR problem (Auto-Dim after 6 Minutes) ? I do not see any updated info on the topic list.
Hope somebody can give us mor information

Hey,
about your first question, I havent noticed anything with the PWM, only if I enable Led Clear Motion in Game Motion Plus it flickers. The HDR dimming bug is not fixed, but for me its not present in built in apps and game mode. I cant connect my PS5 or blue ray player out of game mode though cause it happens.
Im on 1497 firmware by the way

And the big problem of local dimming not working in game mode with GMP OFF? Nothing???

How come this problem is still not fixed after 1 year?!
My Q90t (firmware 1497) is showing the exact same issue (when in gaming mode). What a disgrace for Samsung. Guess who's products I will never buy, or recommend to anyone, ever again?

Does anyone have information about the new firmware (2014)?

Some people at avsforum tested 2014 and reports that game mode works great.

I did some testing yesterday and local dimming with Game Mode OFF has been a good improvement, but it's still not working as it should be.

That's a shame. Where did you find the EU firmware?
