The Gefen EXT-DVI-142SL (also known as the EXT-DVI-1:2SL) is a compact, high-performance 1:2 DVI single-link splitter designed to take one DVI source and distribute an identical, pristine digital video signal to two DVI displays simultaneously. This device is ideal for applications requiring the duplication of a DVI signal across multiple monitors, such as retail digital signage, computer-based training facilities, trade shows, or command and control centers. It is designed to work in professional environments where reliable signal distribution and excellent image quality are crucial.

The splitter ensures that every connected display receives a pixel-for-pixel accurate digital video signal as the original source. It is compatible with resolutions up to 1920x1200 (WUXGA) and 1080p Full HD, supporting a single-link bandwidth. The unit features Gefen's Direct Input Selection (Gefen DIS) technology for optimal operation and reliable plug-and-play functionality. It automatically detects the display parameters via EDID (Extended Display Identification Data) management, ensuring the best possible picture is presented on all connected screens.

Housed in a small, durable metal enclosure, the unit is easily installed discreetly behind a display or integrated into a standard AV rack using optional rack trays. It is a straightforward hardware solution that requires no complex software or drivers for installation, providing a stable and reliable method for multi-display DVI applications.
