I recently purchased this receiver and have my Mac Mini hooked to it as a HTPC. The TV is a Hitachi P50S602. I have noticed these two issues when the computer starts/at the log in screen. I am wondering what could be causing this. I have tried the following connectors to the receiver from the Mac: Mini DVI to DVI, Mini Displayport to DVI, Mini Displayport to HDMI. They all do the same. Here are the pictures of what is happening:
I have hooked the Mac Mini directly into the TV and did not experience any issues.
