Windows 7 - Second Monitor Suddenly Not Recognized

Greetings, and thank you for taking the time to help with my question.

I purchased a new PC at my office approximately two months ago, and have been using a two monitor configuration ever since. This setup had been working totally fine until a few days ago, when Windows 7 stopped recognizing the second monitor as Compaq S1922a and started referring to it simply as "Display Device on HDMI."

My graphics card has a DVI output and an HDMI output...neither of my monitors has an HDMI input, so I actually use a DVI-HDMI converter on the monitor in question. As I mentioned, when the configuration was working properly, both monitors were recognized and were set to their proper resolutions. Now, because the second monitor is not recognized, I cannot set it at greater than 720x480 (see attached image).

I've tried the few things that I would know how to do to fix this -- I've tried updating the monitor driver, I've tried using System Restore to go back to a point where both were recognized. Neither of these worked, obviously, and I'm not sure where to go next. Any help would be greatly appreciated. Thanks!

my guess would be that it updated the driver.  try to roll back the driver for the hdmi through device manager
nbkmarketing--Uninstall and reinstall the problem monitor.
In device manager ..under display driver there should be just one video driver...if you find logmein mirror driver or other driver ..disable it and check.

I looks like you have your "Primary Display" and "Secondary Display" settings flipped.
Try setting the DVI connected monitor as primary and see if it changes your available settings
for the HDMI connected monitor
I'd start with swapping cables.  I also use HDMI out to a 24" monitor's DVI input.  I was trading cables with another location, and it stopped working. Turns out the 10-ft cable did not work,  But the cheap 6-ft cable was fine.

Make sure you haven't bent/twisted your existing cable, as slight damage can mess up the signal & make it unusable.

Thanks for your help...after going through these steps, I was able to determine that the monitor is, in fact, faulty. It is still under warranty from HP, and they'll be sending me a new monitor next week.
