Main monitor blinking

I am running plugable uga-2k-a on second monitor w/ main monitor running on hdmi. Problem is that hdmi monitor blinks on and off frequently. Sometimes several times a minute. I have tried the drivers from your site but cannot figure it out. If I disconnect the usb monitor the issue goes away. If you can assist me with this one problem then I will be set…
