I am running Win 7 64 bit, dual core processor, 4 GB RAM, using a 'Plugable UGA USB 3.0 adapter.' It is plugged into a fully functioning USB 3.0 PCI Express card. The USB display adapter has a solid green light, and is detected by the computer. The hardware ID does not indicate a malfunctioning (or broken or whatever it is -malfunctioning display adapter).

The system has been rebooted, the drivers are all up to date. The 3rd monitor, which I am attempting to connect works on other computers. The monitor is a ViewSonic VA2703. I attempted using the DVI/VGA adapter also, a myriad of different DVI and VGA cables, and another type of monitor. All to no avail. Any help would be greatly appreciated.
