why do I have to unplug the usb 2.0 to vga adapter when I start up my computer

The problem is I have to unplug the adapter and plug it back in again
almost every time I open windows to get it to work.
Yesterday the monitor i have plugged into the computer was flashing on
the top half of the screen.
I use DisplayFusion Pro v7.1 - any known conflicts? Also Flashplayer
Plugin 16 0 0 305.

For the folks that are following this thread and would like to know the outcome, this issue was resolved with a clean DisplayLink driver installation as well as bringing the GPU driver up to date.

so far so good I’ll be working for a few days to determine if this really solved the problem
