The Gefen EXT-DVI-142DLN is a professional 1:2 Dual-Link DVI distribution amplifier designed to take a single Dual-Link DVI video source and distribute it simultaneously to two DVI displays without signal degradation. It is commonly used in control rooms, broadcast facilities, medical imaging environments, digital signage systems, and professional AV installations where high-resolution video must be displayed on multiple screens with identical image quality. By regenerating and buffering the incoming DVI signal, the unit ensures that both connected displays receive a stable, synchronized output even over longer cable runs.

Engineered for demanding professional applications, the EXT-DVI-142DLN supports Dual-Link DVI resolutions, making it suitable for high-pixel-count displays that require more bandwidth than single-link DVI can provide. The device is purely a signal distribution solution and does not scale, convert, or process video content. Its rack-friendly metal enclosure and external power supply design make it suitable for permanent installations where reliability, continuous operation, and signal integrity are critical requirements.
