Thanks for any helps on this one, its got me tearing my hair out.
I've got a HTPC with a new ATI 5450HD with HDMI, connected directly to my Pioneer VSX-520
The LG 42LC7D LCD-TV is connected to the HDMI out on the VSX-520.
Here's what happens in a nutshell.
With no catalyst drivers installed, standard Windows 7 VGA, I can get the HDMI output to work. But of course the resolution etc is not perfect.
If I install the catalyst drivers and reboot. I can see the BIOS screen come up, then the Windows 7 boot animation, and then the screen goes blank. Nothing more.
If I log in to the HTPC with logmein, Windows 7 says its detected the display as "VSX-520" and the resolution is set to 1360x768 (which is the correct resolution for the LG 42LC7D). I can't select/detect any other displays.
Any help please?
