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?


If you plug the main monitor into the HDMI port and leave the secondary
unplugged, does the primary monitor work? If it does, then I would think
that the graphics card is OK. If the primary remains blank, well, you see
where I'm going here :-(


The HDMI didn't work when I plugged it either port.
I think my next step will be to take the monitor and plug it into
another machine. I suspect it may be the monitor.



Have you tried plugging it into the mains? And *checking* it is
plugged in?
And have you tried flicking the "on/off" switch/button on the
monitor?
Have you checked the brightness?

Yes, those are stupid questions but you'd be surprised by how many
"my computer is totally broken" calls to the help desk end with a
quiet "oh!" when they are asked.
