top half of monitor pink vertical lines
 

I am using DisplayLink USB 2.0 plugable monitor.
A few weeks ago pink lines started appearing on my second monitor (the one connected to the DisplayLink USB 2.0 gadget. So I tried a new LCD monitor with a new VGA cable and I still have the same problem. Then I changed it to DVI cable brand new cable and I still have the same problem. I updated the DisplayLink software it is running DisplayLink Manager version 7.5.54018.0
But I still have the problem.

Hi,

This sounds like a hardware issue.

I'd recommend contacting Plugable for support:
