Hello,
All of the sudden one of my two displays stopped working and looks like this:

I tried reinstalling the drivers, even a format of the computer and nothing worked. Still I can only use the one monitor.
The setup is Windows 7 Sony Vaio Laptop (i7) with two external displays each connected to a plugable usb 2.0 adapter.
Any ideas if this can be fixed somehow or is it a hardware error?
