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?

We have a cat who enjoys chewing on all cables and cords. Our solution
is something called "split loom cable wrap." It is a wrapper for cords
of all sorts. You cut an appropriate length of wrap then put the cable,
wire or what not in it - the wrap can be pulled open length wise so it's
relatively easy to apply. We have used around a thousand feet of the
stuff (plus or minus a few hundred) and we use more every time a new
electric device is brought into the house. We have wrapped cords from
appliances, extension cords, all cords and cables to and from our
computers and entertainment boxes (TV etc.).

This cat is a destructive idiot and shows no signs of maturing -
youngest of five by several years. We like him so we will continue
ordering split loom. Fortunately we discovered the problem and solution
before he did too much damage. The most expensive loss was the
recharging mechanism for my electric toothbrush: $80 since the part was
no longer supplied by the manufactured.

Pet your puppy for me!
