I just bought a USB 3.0 Plugable HDMI-DVI Adapter. I am plugging it into a Lenovo Win7 Laptop for a 3rd monitor. They system was working fine for over a year in the previous configuration with 1 VGA monitor. Now with the new monitor, the computer freezes after 20 minutes of use. The 3rd monitor works fine before the freeze happens.
Once it freezes, the only thing I can do is hard reboot it by holding down the power button. It then freezes about 20 minutes later. I have only noticed the freezing after a brief period of inactivity.
Now I am running the system without the 3rd monitor for a few days without freezing.
I downloaded the latest drivers from the website before initial install.
The laptop does not support USB 3.0. I bought the 3.0 version so that when I upgrade the laptop in a few years, the Plugable will work even better.
