I am having an issue getting my third monitor to extend. I currently am using a Lenovo Thinkpad T500 and have used an AOC 2640W as my second monitor plugged directly in to the VGA input in the docking station of the Lenovo.
I recently bought a UGA-165 to connect a third monitor to the Lenovo. I tried connecting an HP w2207 monitor through the Plugable USB 2.0 (UGA-165) and am experiencing issues recognizing the extension. My computer recognizes that there is a third monitor connected, and I can actually move an object off screen (to the right where the third monitor should be displaying), however my HP monitor continues to duplicate my 2nd monitor (The AOC monitor) rather than displaying the space that the third monitor should occupy. I have tried connecting through VGA and DVI, and neither changes anything. I have also moved the configuration of the three monitors to put the 3rd monitor in the middle, and it continues to recognize the space, but not display it. Is there anything I can do?
The green light is lit up and I am using Windows 7. I am using DisplayLink Manager Version 7.8.63104.0.
