I rearranged my living room so I had to unplug my computer. I plugged everything back in including my Sony 46" LCD and my Samsung 21.5" monitor. Everything booted up properly and the Samsung was my main display. I decided I was going to update my video drivers so I went to nvidia and it did the auto detect graphics option. My monitor lost signal. I rebooted and tried both DVI outputs but it would not display on my monitor. I tried my Sony LCD TV which is connected via DVI to HDMI cable and the computer displays fine. I tried clearing the CMOS, removing mobo battery, reseeding the video card, and booting with 1 stick of RAM. When I go into screen resolution settings it detects my Sony TV but when I click auto detect it says no display detected. My monitor is connected to my video card via DVI to DVI cable. Any suggestions on how to get my video card to detect my LCD monitor?
