I use two monitors. I have one monitor with HDMI and another monitor
that uses DVI. The HDMI is primary.

I was using the computer and both monitors went blank. I found the
problem. My dog chewed the plastic off the HDMI end next to the
computer.

I replaced the HDMI cable and neither monitor came on. I pulled out
the Graphics card.

I can plug the DVI into the mobo and it works. When I try to plug in
the HDMI the second monitor switches from primary to secondary, but
the HDMI monitor won't come on. I can unplug the HDMI and the other
monitor becomes primary again.

How do I get both monitors working again and then how do I tell if my
Graphics card is bad?

The problem turned out to be the 25 ft HDMI cable. I have used the
cable before to connect my laptop to my 50 inch TV, but I quit using
it when I bought the WDTV player.

I tried using the HDMI cable with the WDTV player to just test it, and
I could see the opening screen but it would the picture would flash in
and out.
I bought a 10 ft cable and all is well.

I sure am glad my video card did not get fried.

Thanks everyone
