The Gefen EXT-HDSDI-144 is a 1:4 HD-SDI Distribution Amplifier which is a video splitting device that allows a single SDI video source to send data to four HD-SDI displays at the same time. Crisp, highly defined visuals are generated for each distributed output, and multiple formats (NTSC, PAL) plus high definition video resolutions (720 to 1080p) are fully supported.  Connect your source to the Splitter's HD SDI input, then connect your four displays to the Splitter's HD SDI outputs. Once the source, the displays and the Splitter are powered and connected, your source's video appears on all four displays simultaneously.

What is SDI?
