Featuring the DisplayLink DL-125 USB 2.0 graphics chipset, the Plugable UGA-125 enables multiple monitors with any laptop or desktop (one adapter required per monitor, up to six on Windows). Most people use it to gain a third or fourth monitor for their laptop. You get the full benefits of USB, including plug and play connectivity, thin and flexible cabling, and ability to connect via USB 2.0 hubs and repeaters. Multitask with a dedicated monitor for each document or application. Performance
USB graphics adapters work by rendering 2D/3D with your computer's CPU and GPU, and then compressing and transmitting the pixels that change over USB. Dual core or 2Ghz or better CPU recommended. Recommended for web and applications, not 3D gaming or motion video playback. Connectivity
The adapter package includes the main USB 2.0 to DVI-I adapter, a USB 2.0 cable and hardware adapters for the different connector types (DVI-I to VGA/D-Sub and DVI-I to HDMI). HDMI connections are graphics only - this adapter has no audio function. Supports monitors and PC-compatible TVs up to 1440x900 or 1280x1024. Powered via USB with an LED indicator light. Drivers
Windows 7/Vista/XP drivers installed automatically via Windows Update. 32 and 64 bit supported for both Vista and Win7. Vista Home Basic and Win7 Starter Edition disable multiple monitors and are not supported. GPU is used for 2D/3D rendering on Windows, requiring Intel, nVidia, or ATI primary WDDM driver. Not compatible with ARM-based Windows (MS Surface). Not recommended for use on Mac, as only beta-level OS X 10.4+ Intel 32/64-bit driver available via download, and Mac has lower performance and functionality than Windows for USB graphics. Open source available for Linux and other platforms. Linux requires xorg.conf editing (advanced users only). USB graphics devices with different chipset drivers (MCT, SMSC, DisplayLink, etc.) should not be mixed on the same system.
