I have an ASUS laptop running on Windows 7. I recently purchased a StarTech USB-VGA adapter to connect a 2nd monitor. When I plug in the adapter my screen goes black and I have to do a hard reboot to get it to recover. I tried the adapter on another laptop and it works as advertised, no problems. I followed the instructions and downloaded the latest driver prior to plugging in the adapter but that did not make any difference. Any suggestions as to what to try next?
