Do some of the squares flash up, as in getting brighter than they should be when they change color?
I know there were some much more severe cases back then, which I couldn't reproduce. On mine the problem only shows up during specific scenes and it's quite rare.
I just want to figure out if all panels show this problem to some extent.
OK, have run your Oled_flashing_near-blacks_test_6minutes_(play at_default_settings).mkv, and it can be a little tricky as what you think may be a flash, is actually a colour change.
However it seems that only squares 4,5,6,7 do not flash. Square 4 was the trickiest, as it may have flashed a little and only occasionally if so.
The other squares were all pretty steady through colour change.
In general the flash was not bright.
I also ran your previous near_black_flicker_test.mkv, the one you posted some time back.
This showed some flashing only when the rectangle moved. There was no flashing when stationary. The rectangle is a dark grey colour.
Again, the flashing pixels were relatively few in number, located mainly at the bottom of the rectangle and a faint grey/yellow colour. When not flashing the pixels were black.
I also ran the Revenant where forum members iSeries and Adamd reported an issue with macroblocking.
I do not have the UHD disc, but the standard bluray at 1hr 17min 29secs and at around the fire scene in general showed absolutely no evidence of macroblocking. The picture was clear, clean and without artefact.
So maybe you can tell me what all this means, because I don't know.
I am not concerned however, because I do not have an issue when viewing real world video content, apart from some minor compression artefact occasionally.
