Help with Dual Monitor Display ATI Raedon HD 5700

Hello, I recently hooked up another monitor to my computer. My Graphics card is a ATI Raedon HD 5700 Series, it has 2 HDMI ports and 2 DVI ports. I hooked up the monitor worked perfect, until I restarted my computer the next day. The second monitor went to the lowest resolution setting possiable which is 640x480. I go to the ATI control center, and try to change the resolution and it wont let me. 640 x 480 is the only option. So I decided to try something and I unhooked the monitor and plugged it into another computer then unpluged and plugged into the computer with the problem and it worked fine...until I restarted. I updated the drivers but that didnt work. Any ideas?

  6. if u cant provide the graphics card, i have no way 2 know for sure if its an issue with the graphics card or something else
  7. Normally going on the display properties will tell you what card it is exactly. If I'm not mistaken going to your device manager should tell you for sure, that is if you're using Windows.
