The purpose of an HDMI Matrix Switcher is to allow several high-definition sources to be switched onto one or multiple HDTVs. HDMI Router Switches are available in 4×2, 4×4, 8×8 or even 16×16 port configurations. All the switches support the latest trend in high-definition television sets, 3D.
On a 4×4 HDMI Matrix, there are four HDMI connections for inputs and four HDMI connections for outputs. Look for an HDMI Router device that has EDID management and EDID memory.
Why is EDID important?
EDID stands for Extended Display Identification Data.
When a source such as a DVD player or cable set top box is switched on and it has something connected to the HDMI port the source will request information about the display. The display will then respond with a manufacturer identifier and capability information. This capability information defines what resolution the screen can support 720p or 1080p and other display information.
HDMI also contains audio support so the EDMI management gathers that information too. For example, is your set configured for Dolby surround sound or does it only support 2-channel / speaker audio?
EDMI is what allows you to quickly switch between devices without long pauses using an HDMI matrix. Some units support switching and device recognition in as little as 2 seconds.
