Hi - I have a Dell desktop that I need dual monitors set up on. I purchased an NVIDIA GeForce GT610, that has 2 DVI ports. I also purchased 2 Samsung 27" monitors to connect to it. When I connected the monitors to the video card, the computer would start up, but screens were black as if they werent even connected. I checked the menu on the actual monitors and made sure they were set to DVI instead of VGA, and both were set to DVI. I then unplugged 1 of the monitors from the card to see if that may be the problem, and STILL wouldnt show the monitor. I then switched the monitor with another one from the office (smaller one) to the DVI port on the card, and it worked fine, as well as taking the new samsung monitor to another computer, and that worked fine. So i've at least eliminated the card and the monitors as being bad or a problem. While the 2 montors were connected to the Nvidia card on the new computer, nothing showed on the monitors, but I setup remote access to the PC, so I was able to log into it remotely. The resolution was at 1024x768 and i thought that was the problem, so I changed to to the highest resolution (2560x1600) and still nothing. Its a Win7Pro machine, so on the desktop I went into the display properties, and it only showed 1 monitor there(screenshot attached), I attempted to detect, but it didnt find anything! Not sure where to go from here - any help would be appreciated.
