Optiplex 745 - Dual Monitor Support

You need to to obtain a dongle. Depending on the output type of your video connection, it can be DVI to DUAL DVI, or VGA to DUAL VGAor even VGA to DUAL DVI. Im not sure where to get these, but you will need something like this with a single head that supports dual display.

If you right click on your desktop, goto properties, and then click on settings, do you see two screens with one dimmed out?

Thanks for the responses. Yes, I got the cheapest graphics card option by mistake and I've been trying to figure out how to resolve it. I will try to install a better graphics card in the computer. It complicates things a little that it is a small form chassis with low profile expansions slots.

Thanks again,

Low Profile = Itty Bitty power supply = not really upgradeable.

I actually got a low-profile graphics card that does support two monitors, so I'm fine now. I wish I had known more about the limitations of the smaller form factor computers when I made the purchase, though.
