New D2 with v1.21, Set it up and saved User Settings. Great Video & Audio.
After making some changes in setup, I re-loaded the User Settings. Immediately the picture began to shake/jitter, horizontal lines and horizontal dots all across. All sources have the same problem, Audio is fine. I proceeded to disconnect my 3 HDMI sources and just put the OSD on screen. Still the same problem. Turn both TV & D2 OFF then back then back ON). Same problems on all sources and on OSD. To eliminate the TV, I connected the sources directly, problem gone (not the TV).
I contacted Anthem service via email and they recommended that I load v1.29k, which I did last night. Powered the D2 back ON after install and all is fine. New firmware loaded perfectly and version confirmed by Status.
I tuned off the D2 from the front panel and turn it back ON later to find that the video problem is the same as before. Proceeded to turn TV & D2 off (front panel) then back ON a few times. Same issue. I then powered Off the D2 (with the rear switch) and then back ON. Problem the same. I found that if I power Off the D2 (rear switch) for more than 5 minutes and then back on the video is fine. I can switch sources back & forth and video remains OK.
I also noted that if I change the Video Out Config from 1 to 2 (scrolling down in setup) the problem re-occurs (Config 2 is same as 1). The only way to get the D2 to perform is by powering it off for 5-10 minutes. The D2 is in the open so it is not a heat problem. I also tried different Video Out resolution to TV.
I re-loaded the v1.29k firmware but this has not resolved this issue. I tried to turn the TV ON way before the D2 of after the D2 w/o success.
Note that I had a loaned D2 (v1.2) for a few weeks prior to this w/o having any of those issues. My setup/components are identical.
