UGA-165 Green light ON, still wont work.

Hello. I have a UGA-165 (USB 2.0) Plugable graphics adapter I would like to use to make a TV into a 3rd monitor. As soon as I pluged the hardware into my computer the green light turned on and the feed disappeared from my second monitor and reappeared on the 3rd (the one attached to the UGA165). I have downloaded the Windows DisplayLink 8.4M0 driver via this website. How can I get the 3 monitors i want to work together? Is the Plugable hardware incompatible with other graphics cards that come with commercial computers?

Thanks for contacting us!

I’d like to take a look at your system and see what could be going wrong. Could you contact me at so I can investigate?
