Sorry, I still don't get it!
What's the difference between "camera" and "pc"?
I don't have hdmi in either of them. What I have is an Android tablet with HDMI.
It works with HDMI channel (the picture is cut off but there is a picture) but doesn't with DVI (the screen flickers, looks like the monitor goes between On and OFF every 2-3 seconds)
Please specify what is the difference between HDMI and DVI "channels"
