The Samsung Syncmaster 940UX is a 19" LCD flat-panel computer monitor. It is the first monitor that can connect to your PC over USB without the need of a video card. While supporting DVI and VGA inputs, the 940UX has a USB 2.0 port that accepts video; this technology allows you to connect up to six 940UX monitors to a single computer without the need for any special video hardware.

The burden of displaying video when using the USB interface is done by a DisplayLink video processor located in the monitor itself. This technology works in a similar way as the Remote Desktop Protocol (RDP). In USB mode, the 940UX is limited in that it can't display any graphics requiring 3D acceleration, so it cannot be used for gaming with the USB connection.
