Optiplex 3020 micro 3 monitors
Hello,
I have baught a display port to 3 display port mst hub link here.
The device work and i see my 3 screens in the displayport topology
The issue is that i cant have more than 2 screens working at the same time
On the intel multiscreen setup page i can only have 2 screens but i have the choice between my 3 screens
same in the windows configuration panel the third screen is disabled even tho it is detected
How can i enable my third screen ?
Is there a bios option ?
the intel 4400 i have is supposed to support 3 different screens over a single display port why isn't it working ?

Hello ChrisDup,
If you are trying to use all three monintors using DisplayPort, then it wouldn't work. This is an unsupported configuration, review the unsupported configurations here. The only way you can have all 3 monitors working in your setup is to use the VGA port on the board for one of the monitors.
Hope this resolves your issue.

I'm using a splitter on the VGA. Using a projector for PPT and would like to have the 3rd monitor set up to where it is not mirroring what's on the projector (classroom set up). That way I can monitor what students are doing on their computers, as well - had have the main monitor to my self. I am using an Optiplex 3020... 3rd monitor is not showing up. How do I get this to show up?

You have to buy expensive hardware.
