Weird Monitor/Graphics card issue? Please help

Hey guys,

I have the following two monitors and video card and am having a strange issue.

I currently have the 27inch HP hooked up to my gtx470 via HDMI to mini HDMI to the card. I have that selected in windows 7 as my main #1 monitor/display. My smaller 22 inch LG is hooked up via DVI with both sides of the connection to the same video card. This monitor is setup as my #2 display/monitor. All of a sudden last night, I lost the display image on my main 27 inch monitor and it told me it was going to sleep. I still have power to the monitor, lights and all work, if I hit menu it works and can select HDMI and when it shows it scans for hdmi, dvi, or vga shows red and none found. I unplugged and replugged in all connections and nothing changed. Windows does not detect a second monitor and has my 22 inch monitor defaulted back to my #1.

I then took the hdmi connection cable and took it out. I replaced it with a stand DVI cable from my 27 inch to my video card. So I now have both monitors into a DVI port on my gtx470. My 27 inch monitor now works, but my 22 inch monitor does not display and image and windows can not find it. I am curious if my video card just stopped supporting two cards? Let me know please. I want to know what I need to replace or trouble shoot. Thanks guys.

Video card drivers are NVIDIA 327.23 most current drivers.
