I have an Intel Mac Mini connected via a DVI-to-HDMI cable to the Denon AVR 2310CI. The Denon is connected to a Sony HDTV via HDMI.
When I log into Mac OS X I am able to see the desktop just fine. But when I log in to the Windows 7 Boot Camp OS, I only see the initial black screen with "Starting Windows" but as soon as the desktop is supposed to appear, the screen goes blank. The TV behaves as if there was no input supplied to it.
I connected the mini directly to the TV and all was ok. Something's up with Windows 7 (and earlier, I had Vista and had the same issue) connected to Denon.
Any clues about what I can do to make the display appear?
