This makes the flickering go away while still capable of running 1080p/24 for blu-ray. However, 1080p now runs in 1080i. I have sent a note to Denon and will update my finding.
Please do report back if that does not completely rid you of the flickering. I've noticed that making changes may appear
to solve the issue for awhile, but it just comes back.
For example, this morning I turned everything on in PS3 mode and it was sending the Denon 4810 into a tizzy with full screen flickering and complete momentary loss of signal (TV going to blue and Denon losing all input signals), i.e. the worst that it gets sometimes. I had already tried turning off 1080p in the PS3, or even everything but 720 and nothing worked, except that letting it go solely in 720 greatly reduced the flickering (and who knows for how long). That's obviously no solution anyway.
So, I decided to attack it from the Denon settings again. I set video to 1080p/24 only (instead of automatic) and the flickering went away. I couldn't watch for long, but it was clean for a couple minutes after having just gone haywire. BUT here's the thing - I realized in a moment that I had accidentally set the video via the analog
submenu instead of the digital submenu. Since I'm running it via HDMI that should not have made a bit of difference, right? Yet it did. I just wanted to give an example of completely arbitrary acts seeming to fix the problem, only to (probably - will report back tonight) have it come back later.
As I previously mentioned, I don't seem to have this problem with movies (only tested on BR thus far) or disc-based games. I can get flickering in downloaded games and most often in the menu system. I suspect there's a resolution factor in play there, but I'm far from being an expert on this stuff.
