This plugable display adapter allows you to connect an additional monitor to virtually any Windows laptop, desktop, or tablet PC with an available USB 3.0 or 2.0 port. Supports DVI, VGA, and HDMI displays up to 2048×1152 with included passive adapters. (One adapter is required per monitor, up to six adapters supported on most PCs.)
It features the DisplayLink DL-3100 USB 3.0 graphics chipset, and works by rendering graphics with your computer’s CPU and GPU, and then compressing and transmitting the pixels that change over USB. 2GHz dual core or better CPU and at least 2GB of RAM recommended. Best suited for web and productivity software, not 3D gaming or HD video playback. No power plug is needed – power is provided by USB and the adapter has an LED indicator light.
