I have been using a Plugable UGA 165 adapter for almost 2 years on a Windows 7 desktop. Worked great. Yesterday I unplugged it so my wife could use the adapter for a presentation. Plugged it back in an hour or two later and my desktop can’t see the 2nd monitor.
I have downloaded new drivers and the desktop recognizes when the USB is plugged in. After fiddling in the control panel display area (by setting it to “Display device on:VGA”) I can get it to see the 2nd display. However the 2nd monitor screen stays black. It is not receiving any input. I have switch the monitors around how they are plugged in . The one attached to my video card is always recognized and the one through the adapter is not. I have tried everything I can think of. Any help would be appreciated.
Thanks in advance.
