When docked, a monitor attached to the VGA (HD 15) port works great, but the same monitor attached to either of the DP ports does not redraw correctly. That is if I move a window there is a trail of pieces of the window from the original position to the new position. Similarly, if I do an `ls -la' in a window the files are not visible unless I slightly move the window, hit enter, or otherwise cause the screen to be redrawn. I have tried several different cable and monitor combinations all with the same result. I am happy to provide any additional info.
