Once I purchased my MX-500 learning remote, I wanted to use the DVI switching offered by my 1070, as my TV doesn't have discrete codes for input sources.

I've bought a set of three DVI to HDMI adapters form monoprice and I've run into an intermittent issue with my 1070.

While the picture quality through the DVI switch is, as expected, same as when the Oppo 980H and the Motorola cable box were connected directly to the Samsung TV via HDM cables, every once in a while, when either powering the system up or switching from DVD to TV, the TV image doesn't come up right. The aspect ratio is wrong. And it's not wrong like the wrong option was selected, 16:9 vs 4:3, but HD material shows up vertically compressed and horizontally expanded. The only way to fix it after it happens, is to power 1070 off and back on. Powering the TV off and on doesn't cut it.

Did anybody else experience this?

I'm not quite sure what I might be doing wrong, if anything, for the system works OK 8 out of 10 times... There are no sparkles or signal interruption, to blame the DVI - HDMI adaptors or the cables...
