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?

I wanted to test to see if the HDMI monitor was working. I have a
Firestick so I plugged that into the HDMI port and the monitor worked.

Someone suggested the onboard HDMI and the DVI can't work at the same
time. So I unplugged the DVI and plugged in the HDMI. The HDMI does
not work. The spare cable I have is a 25ft HDMI cable that was
working the last time I used it.

How can the monitor work with the Firestick and not work with the 25ft
HDMI cable?

I don't think either monitor was plugged into the mobo and both were
plugged into the Graphics card. It seems very remote that the mobo
port was effected by the chewing HDMI plug.

I still have not put my Graphics card back in the computer. What
should I try next?

Perhaps pick up a replacement HDMI which is the same
length as the one the dog chewed ?

It's possible the onboard chipset graphics aren't detecting
the HDMI termination resistors. Or, maybe a setting needs
to be made somewhere to change ports (it's decided not to
auto-switch on its own). On a laptop, you'd have an F-key which
you could use, to switch the graphics output from port to port
on the GPU. I doubt the binding for such is set up on a
desktop.

Maybe you could use the chipset VGA to one monitor,
then try to bring up the chipset graphics Display
panel and enable the HDMI from there ? Grasping
at straws here...
