    I'm running Windows 7 64bit, ATI Radeon 5870 HD x2, and my monitor is a Samsung SyncMaster T240HD (Digital).
    I've always used a DVI-D cable which plugged into my first video card. Everything ran fine, I'd have zero display issues. I decided to switch to HDMI since my monitor kept Auto-adjusting brightness...

    Whenever Windows starts up, I receive no signal. I have to unplug the HDMI cable from my video card and plug it back in when windows has booted for it to work. I get the Windows sound which you hear when plugging in a new USB device. Sometimes it takes multiple restarts before my monitor shows my display again.

    When it finally shows my display, all my desktop icons are scrambled all over the place and my Catalyst control center shows that my Crossfire has been turned off, sometimes when I re-enable Crossfire the screen will go black and I will once again get "no signal". I'm at a loss, which factor is at fault here? The Monitor? The OS? or GPU? Any suggestions on how to fix this annoying problem would be appreciated... Again, once the computer finds my HDMI signal it works great up until the next shut down and boot up of my computer.
