I have a Dell OptiPlex GX620 desktop. It has both a VGA and a DVI-D adapter installed. Currently there is a VGA monitor connected to the VGA port. I want to add a 2nd monitor for the purpose of extending my desktop, but I only have another VGA monitor available.
I've purchased a DVI-D to HD15 VGA adapter and plugged the VGA monitor into the DVI port, but nothing comes up on the display. When I try to enable extending the desktop and I click Apply, the check mark disappears.
Is there a way to accomplish the extended desktop, with the monitors that I have? Thank you!
The Dell OptiPlex GX620's that we have, contain 2 video cards. One is on board and the other is a riser card! The PC's definitely support dual monitors, when a VGA monitor and a DVI monitor are used. We don't have enough DVI monitors, so that's why the dilemma!!
I appreciate all responses, but the VGA & DVI can both be used together, when you have both a VGA and aDVI monitor. The 2nd monitor can be used to extend the Window's desktop and works quite well. We've got over 50 users who have this configuration. As stated, our problem is that we've run out of DVI monitors and need to connect 2 VGA's but still need to extend the desktop onto the 2nd.
