Hello

I'm using a Dell Optiplex 7020 with Intel HD graphics. Using a Wavlink Dock model WL=UG39DK3 REV A. I have the latest drivers installed.

The dock seems to be working fine, Network, usb, audio and Video work. I have two other displays plugged in to the back of the PC. One runs a TV and the other a monitor. When I have Dispaydock drivers installed I can't change the Main Display from the TV to the local monitor. Everytime I click the check box "Make this my main display" the screen flickers and it resets to the old setting. If I remove the display dock drivers I can set either monitor to be the Main Display.
