GeForce GTX 745 Compatible with DisplayPort MST?

Hi Community,

I am wondering if anyone knows whether I can use 4+ monitors with my current system configuration:

Dell XPS 8900 with a GeForce GTX 745 graphics card.

I currently have 3 monitors using DVI, VGA and HDMI connectors. I am wondering whether I can connect a fourth monitor to the onboard DisplayPort connector as well? Since the graphics card only supports three monitors, I may have to remove one of the existing (DVI, VGA or HDMI) and daisychain or use a hub for a second DP monitor.

Can I have two DP monitors and two of either DVI, VGA or HDMI with this system?

Asking because Dell customer service over the phone did not have an answer.

Thanks!

Re: GeForce GTX 745 Compatible with DisplayPort MST?

The GeForce GTX 745 cannot drive a dual monitor daisy chain because that video card does not have a DP or mDP out port.

The XPS 8900 onboard DP out port cannot drive a dual monitor daisy chain.

There are three options for video port usage on the XPS 8900, all based on what you choose in the Bios- Display;

* Set it to Multi Display Disabled, Primary Display Intel HD Graphics
- Remove the added PCIe x16 video card from the system
- Use either the onboard HDMI out or onboard DisplayPort out

* Set it to Multi Display Disabled, Primary Display Nvidia HD Graphics
- Use the added PCIe x16 video card as your only Graphics
- The onboard HDMI out and onboard DisplayPort out are turned OFF

* Set it to Multi Display Enabled, Primary Display AUTO
- The onboard HDMI out is Primary
- The onboard DisplayPort out is Secondary
- The added PCIe x16 video card ports are Tertiary, Quaternary, Quinary
