With the Split 312, you can distribute the HDMI signal from your decoder or another HDMI source to two televisions. This is ideal if you want to display the same presentation or movie on two screens simultaneously. Since the switch supports 4k2k and 3D, it can be connected to your Ultra HD televisions. It allows you to play the video and audio from your digital TV decoder, satellite receiver, gaming console, or Blu-ray player on two screens (TV or HD projector) at the same time. There's no need to swap the HDMI cable when you want to watch movies or play games on a different screen. It supports HD audio systems and all other common audio formats. With the unique EDID switch, you can determine the maximum video resolution at the HDMI output if desired.
