Is it possible for the black levels on these sets to actually lower (basically the opposite of what some of the Panasonic plasmas were doing)? I just noticed some extremely odd behaviour from mine, unless my vision just suddenly changed over the last few weeks. When I got the set in July, I ended up settling on:
This is in a completely dark room with it hooked up to a PC using RGB Full. I checked it again later with the ISF stars patterns as well as the gamma clip from this thread. Everything lined up. I even rechecked a few weeks ago.
While watching a show last night that had quite a lot of black and near black scenes, with people either being in the shadows or having black leather on, it just looked wrong. It seemed like I was getting a lot of black crushing. When they would be outside in direct sunlight, it looked better, but not quite natural. For the hell of it, I decided to switch over to gamma 2.2. The screen got "brighter", but it wasn't quite washed out. Everything looked a lot better for some reason, and it goes against my previous tests as well as thoughts on the media I had been previously viewing all of this time.
Just now, I went back and tested with the slides again with BT.1886. It wasn't correct. Gamma was off as was the brightness. I double checked to make sure none of the luminance levels were altered from the default (since I did toy around with near black levels briefly, but wasn't satisfied, so I set it back to 0). Putting it back to gamma 2.2 as well as adjusting the brightness to 53 had everything pass again, which includes the flashing black bars, that I previously gave up on trying to use with this setup. 17+ was blinking.
The only things that are different between when I got the set and now would be the two or three firmware updates, a driver update for my graphics card as well as playing some games in HDR. I don't know if there's any possible correlation here either, but Resident Evil 7 on PC has an HDR mode, but it's completely ****ed up. If you shut it off, it looks like it's gamma blasting the screen and turning the in game brightness all to the lowest level is like you have it near the maximum (I've been able to play the game with another monitor without this problem happening). If the B6 starts out in HDR mode (which the game originally forced this TV into automatically without any choice until it was patched), the non HDR mode is completely off brightness wise. You have to turn the TV's brightness down by 6-8 over where you originally had it for it to look even remotely right.
Maybe the video card drivers changed something, but I've never heard of this happening. All I know is that the settings that the TV was calibrated to for almost seven months are now no longer accurate.
