Report "Just bought a new monitor for my Windows 7 64 bit system so that I can run two monitors. I have my primary monitor plugged into the computer via D-Sub cable and the new monitor plugged into my Targus ACP50US port replicator docking station. However, no signal is getting to the new monitor and it appears that the computer will not allow me to extend my desktop. Is this a problem with the Docking Station or with the Computer?"
