Hello,

I am running a 17" VGA monitor that connects via an adapter to DVI-I and running HDMI to my 32" HDTV. I am trying to extended or duplicate the desktop but the screen is just black on my HDTV. I've checked the cables with other devices and other ports on my tv incase there was a dead port and all work fine.

What can i try next?

Running: ASUS HD 7770 1GB 1020MHz (ports: display port, VGA DVI-I, DVI-D)
OS: Win 7 32bit
Mem: 4GB
Mobo: ASUS P5GC-MX
CPU: Intel Pentium D 820 2.8Ghz

so it picks up the other display, which is the HDMI to HDTV, and they are set to the same resolution 1440x900 and set to extend but still no display on my HDTV
(FYI - this is a new video card) could it be the video card? or am i just messing some settings up?
