The Plugable UGA-165 enables multiple monitors with any laptop or desktop (one adapter required per monitor, up to 6). Most people use it to gain a 2nd or 3rd monitor for their laptop. You gain the benefits of USB, including plug-and-play connectivity, thin and flexible cabling, and the ability to connect via USB 2.0 hubs and repeaters. Projectors can be connected with long and flexible USB wiring that doesn't lose monitor configuration information. Multitask with a dedicated monitor for each document or application. The adapter works by rendering 2D/3D with your computer's CPU and GPU, and then compressing and transmitting over USB any pixels that have changed. Dual core or 2Ghz or better CPU recommended. The monitor itself is then constantly refreshed directly from the USB hardware. The adapter package includes a USB 2.0 cable and hardware adapters for the different connector types (DVI to VGA and DVI to HDMI). No power plug is needed - power is provided by USB and the adapter has an LED indicator light.Multiple Displays We often hear customers say "After using multiple monitors, I can't go back!". If you're doing information work - looking at one document while editing another, researching, or generally working on several things at once - it's indispensable.
