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

I'm testing on Xbox One X. I did recalibrate the HDR while in game mode manually. Contrast Enhancer does increase the brightness, but it washes out the image, as if it's really just reducing the contrast instead of increasing it. I am trying to record a video. Not sure how well it will turn out.
I got the 1402 Update from the US Support site.

Just asked a Polish support guy(for q90t update), and he said that each region tests update before launching it so I understand that Europe didn't do it yet. It seems that we need to wait a bit, I was trying to ask for specific day or what fixes were made, but he only said its a matter of near future for 1402 to come out.

Hdr is very dark you know... did you test in SDR ?
you can set the gamma 2.4 for more brightness btw.

I also tried the file supplied, extracted to one folder on the USB stick and on the TV, after the update checks the USB stick, I'm told there's no compatible updates found. In UK, Q95T.

have you tried without vrr?
I remember a guy who said that with VRR on everything became darker.
(btw I reported Suriya)

It’s out in EU for q65t so I guess it’ll be soon.

Let's focus on the firmware ?? This is the focus here. If you can't post anything about it, go elsewhere to discuss what he did or did not do.
