El Capitan compatibility

[Youthman]

Last week I upgraded to El Capitan 10.11.1 on an iMac. We currently have two displays setup from the iMac. Display Port going to VGA to the main projector and then USB to DVI Display Adapter going to a secondary Plasma TV. The main display looks fine but the Plasma TV has crazy green lines and is pretty much unusable. I tried uninstalling the DisplayLink driver and installing both 2.4 as well as the 2.5 Beta and both yield the same result.

If I bypass the Display Adapter, the Plasma TV looks fine.

I went to BestBuy and purchased a J5 USB to HDMI Display Adapter and it is showing the same issue as well.

I can't seem to figure this one out. Any help would be greatly appreciated.
