HDMI problem

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.
The above indicates that DVI works with both monitors (primary +
secondary). If so, that's what I'd stay with until I decided on other
solutions. I surmise "plug in the HDMI" means that the mobo has onboard
HDMI, in which case the monitor has been damaged. IMO the graphics card
is toast.
How do I get both monitors working again and then how do I tell if my
Graphics card is bad?
I suspect that the dog's saliva created a nice little short in the HDMI
cable, which propagated backwards to the HDMI chips on the graphics card
and the monitor and fried something.
So if I wanted to stick with HDMI, I'd replace the graphics card (which
raises additional issues, see below), and the monitor. Or pay a tech to
test and fix the monitor, which may cost more than a new monitor.
I'd do something about the dog, too. Nothing drastic :-), just something
to keep him away from the electronics.
Footnote: Replace the graphics card or not:
Whenever a major component on a system has to be replaced, the question
that begins to niggle is, "Is it worth it, or should I buy a new(er)
system?"
New(er) machines have excellent onboard or in-chip graphics, usually as
good as or better than most graphics cards of yore (major exception:
gaming graphics). Since you're running Win7, I surmise you have an older
machine. If it's 5 years +, a new(er) machine may well be a better
option than repair or upgrade of what you have. Takes a fair amount of
searching and calculation to arrive at a clear enough choice between
repair, upgrade, or keep a while longer. May be worth it merely as a
learning experience. :-)
The problem with getting a new pc now is that it comes with Win10 and
there's no quarantee it will even run Win7 propely as there probably
aren't Win7 drivers for it.
