I could use some help troubleshooting an issue on my 60ST60 where black levels in movie scenes suddenly go from deep black to sort of a washed-out gray, during low-light scenes like "people walking through caves or sewers." Often this looks sort of like flickering between the dark black the backgrounds should be, and a much grayer view. If I go frame by frame through those sequences, the changes occur matching what I see when watching the movie in real time.
It's distracting, and started right after I reconfigured my home theater... everything changed about my home theater setup all at once, except for the TV and it's settings. The TV & settings haven't changed a bit. But there's a new home theater PC (now a late model i5-6600 based machine with Win10, new versions of playback software, etc.), and a new AVR (Denon S720W).
Playing these same scenes of content WITH THE SAME SOFTWARE on my desktop PC doesn't show the "flickering." So, I have no reason to believe it relates to the content.
I tried sending the video to multiple different HDMI ports on the TV; they both showed the same gray-flicker phenomenon.
Based on this, my troubleshooting tree looks like this:
-Is it the content? No.
-Is it the TV itself? Almost certainly not.
-Is it the software? Apparently not.
-Does it relate to the new computer or new AVR?
---Almost certainly yes
-----What on the AVR could cause this? [Don't know, noting in menus suggests it, next step is to test without AVR in the loop]
-----If I rule out the AVR, what about the computer would cause this? Nothing much in the Intel graphics controls that relates to this to try to tweak.
Any ideas about what to do? I'll see about testing without the AVR; physically this may be easier said then done based on available cable lengths.
Mostly, what in a late model Intel driver package would cause this?
Sometimes, I see dead pixels...
