If you have Webtop 3.0, you can hook up your Droid 4 via HDMI to any HDTV or monitor, and you'll be able to select the Webtop option. Your phonescreen will become a touchpad (which is kind of clunky), but it will be the same Webtop interface on the TV/monitor that you see on the Lapdocks. You could pair a Bluetooth keyboard with your phone, though, to make input easier.
