That would take some doing. Have the supplier show you that working. You've left out a lot of detail such as model numbers of the PC, video card, OS, displays, etc.
I do see displayport to VGA cabled but you know those are not functional.
I'm trying to hook up dual monitors for a fellow employee, and his PC has 2 ports: a DVI-I port and a Displayport
I have both a DVI-to-VGA adapter and a Displayport-to-VGA adapter connected to 2 monitors both using VGA connections. The PC will only find the monitor plugged into the DVI port and will not find the other plugged into the Displayport.
Can I not use 2 adapters?
