Can a USB 2.0 Display adapter UGA-2K-A Rev B cause monitor flicker?


#1

I have 2 monitors connected to a Lenovo T430 docking station one of which uses a Plugable USB 2.0 Display Adapter. The screen on the monitor with the adapter has just started flickering left-to-right with vertical lines about 1.375 in apart blinking with the flicker. I have replaced the VGA cable with another and replaced the DVI-to-VGA adapter with another with the same problem occurring. I shut the computer down and checked the monitor without a signal to see if the vibration and lines occurred then. It did not. This configuration has been working for about a year without a problem. Before that I had a UD-3900 docking station instead of the Lenovo docking station. I had to remove it because I was getting a connection problem. Any ideas?
