I have a Dell laptop with a docking station that connects via USB. I have an ACER monitor that I use as my main monitor when my laptop is docked. Recently, a black band has appeared around the edge of the display on this monitor and I can not get the display to take up the full size of the monitor. I have updated the video card and tried disconnecting and reconnecting the USB docking station. Can someone help to try to resolve this?
Thanks in advance.
