I have a Dell XPS L702X running on Windows 7 Professional. When I connect it to my Dell U2312HM monitor (using the USB cable), it doesn't recognize it at all. My monitor has an error on it saying now VGA cable. When I try to select the Input Source, USB isn't even an option. I've tried changing the ports on my laptop, rebooting with the monitor connected, making sure all cables are inserted correctly. Nothing seems to work. Any help would be great.
thanks in advance,
Daniel
