Has anyone had any experience with something like this? I am going to trouble shoot with the board and cables, but it sounds suss to me.
I had something similar. I called them 'sparkles', especially showing against a dark background.
I replaced some hdmi cables and changed the configuration of my hdmi splitter and Darbee Darblet and that eliminated the sparkles.
Before configuration: (the sparkles did not begin appearing until many months of this set up)
AVR > 6' hdmi > Darblet > 6' hdmi > hdmi splitter >> 6' hdmi to TV & 35' hdmi to projector.
I replaced the three 6' hdmi cables and still had some sparkles but less than before. Then I put the Darblet after the splitter going only to the projector... and that fixed it.
Now: AVR > 6' hdmi > splitter > >6' to Darblet > 35' to PJ and the other split 6' to TV.
I'm not sure how much of my problem was the cables or the Darblet, but it's most likely the hdmi cables. I was also getting occasional 1-3 second random video disconnects going to the PJ with the first setup, and those stopped after placing the darblet after the hdmi splitter.
