I have a Dell Optiplex 990 with an AMD Radeon HD 6670 graphics card. I would like to use my two Dell UltraSharp U2711 monitors in a dual configuration with my computer. Both monitors have a single DisplayPort port and two DVI-D connectors. The graphics card has one Displayport and one DVI-D. The motherboard on the computer also has a DisplayPort and DVI-D wired directly into it.
My first guess for how to do this is to connect both monitors directly to the graphics card, one via DisplayPort, one via DVI-D. However, is it possible to connect the two monitors to each other via DVI-D and one to the computer via DisplayPort? Am I correct to assume that I should not use the port wired into the motherboard?
What is the best way to configure the cables for connecting the monitors to the computer?
Thank you for your help.
