Steps to reproduce
It's been like that since I bought this TV more than a year ago and hasn't been fixed yet.
Basically makes the TV super annoying and a really bad buy for watching HDR content.
Update: I just discovered it's not just my model.
If anyone with the same issue has tried streaming with an external streaming box please let us know.
I have a Q80R and I have the same problem, according to the content sometimes it happens and sometimes it does not, it is very annoying, I hope it will be fixed some day.
There is no any bluray player hdmi only hdmi 1and 2 then hdmi 3 earc and hdmi 4 with game
I don't even have in game bcos I wouldn't have 4k@120 on min 1660 super
I have brightness on 25 or 30 as it drains electricity very much on 50
contrast is on 40 the higher contrast it will wash the shadows out I prefer cool instead of warm as the whites are real white not yellow.. But tv millisecond is terrible yeah I can see how it drags...
Obviously nothing is being done to address this issue, 2 years after buying..
I just wanted to add that the same behavior also occurs when hooking up a PC via HDMI and using HDR mode in windows. The same sudden brightness drop occurs every few minutes.
It's frankly unbelievable how many models have this bug and there is not a single mention from the big TV review sites.
