Graphics card is a GeCube Radeon HD3870X2 X-Turbo Quad DVI ports with (HDCP Support) Memory: 1GB GDDR3 Bus: PCI Express 2.0 x16 Connectors: DVI DVI-I & TV Out
Upgraded to Windows 7 from VISTA and started to have problems with 2 of the 4 displays not getting any signal. I've been using 2 DVI 24" LCD monitors and 2 HDMI 32" monitors all worked fine until I upgraded OS, then again when I upgraded MB and RAM.
After I upgraded to Windows 7 the 2 HDMI stopped getting signal, uninstalling and re-installing ATI video drivers finally got signal to all 4 devices, took multiple installs to resolve.
The same thing when I upgraded MB and RAM after screwing with it for weeks finally got all 4 to work. Rebooted and now only the 2 DVI monitors are recognized, no signal to HDMI monitors.
I don't know what's different. Temperature is normal on graphics card, CPU and RAM. GECUBE and ATI/AMD have provided little or no support.

I would appreciate help from those more in-tune with the workings of GECUBE, ATI, Windows 7, video cards in general, crossfire, and HDMI...
