We are trying to add another monitor to our Win 7 desktop that only has USB ports available. We purchased a VGA to USB adapter for the VGA cord, but the PC is not recognizing the Monitor.

 All ideas would be greatly appreciated.

Can you give me the make and model number of the adapter?


Search for


device manager


hit Enter.


View, Show Hidden Devices


Do you see any yellow flagged devices?   Right click on one and select properties then click on the Details tab.  Change Property to Hardware IDs.  Click on the top one then right click and copy.  Paste that into a reply.  Repeat for all yellow flagged devices.


If you don't see any yellow flags can you identify your adapter?  Right click on it and select Properties.  Does it say it is working properly?
