How HDMI Matrices Improve Your Visual Experience in All Scenarios

1. What is HDMI Matrix?

A HDMI Matrix Switch is an electronic switch that route HDMI signals from multiple input sources such as STB, DVR, computers and DVD players, to one or more HDMI display devices, such as monitors, projectors, and TVs.  

Its most prominent feature is the use of built-in multiple display modes, different display modes can be combined in the display to achieve more visual experience. The specific display mode selection can be referred to the following introduction：

1.1 All displays share same input source

 

1.2 Part of displays share different input sources

1.3 Each display select a standalone input source

 

2. Control of HDMI Matrix

2.1 Remote control/Front panel keypad/RS232 or LAN(TCP/IP)

3. Compatibilities

Before we talking about compatibilities of HDMI matrix, we would introduce EDID first. EDID is short for Extended Display Identification Data, it is a data structure provided by a digital display to describe its capabilities to a video source, so the video source could output a video most suitable for the display. In Tesla smart's matrix, each HDMI input source has a EDID memory presented to the source player. And there is a MCU is always monitoring the routing status of the matrix, once the routing status changes, the MCU read and analyze all the EDIDs of the displays sharing same input and create a new EDID which best describes the displays' capabilities for the display. Finally the MCU save the new EDID to the corresponding EDID memory connected to the input source. 

 

4. Different types HDMI matrixes

4.1 4x2 HDMI matrix

4.1.1 Basic connection diagram

 

4.1.2 Used in big meeting room with two displays

• Meeting room is split to two little room, two projectors select different input sources
• Combine two little meeting rooms together, two projectors share same input source. 

4.1.3 Used in home entertainment system

 

4.2 4x4 HDMI matrix

You can choose which output device to display which input device as you want, and you can also display one input device on multiple output devices at the same time, eliminating the troublesome of unplugging cables and switching devices, and greatly simplifying the device management. You can switch input ports with front panel buttons, IR signals and RS232 port.

 

4.3 4x4 HDMI seamless splicing matrix

The 4 x 4 HDMI Matrix Switch can route any of 4 HDMI video sources to any of 4 HDMI displays, with a quick view of all port connections via the front panel LCD. The matrix supports multiple control methods, front-panel pushbuttons, IR, RS232 and TCP/IP.
It supports seamless switching of HDMI sources with same resolution, ensures no switching delay and no blank video delay. And supports 2X2 video wall mode, provide you an ideal solution for applications that require multiple HDMI displays with multiple HDMI sources to be conveniently setup in multiple locations. 

 

4.4 4x4 HDMI matrix（Independent audio/4K@60hz）

This 4x4 HDMI matrix routes 4 Ultra HD sources to 4 4K Ultra HD displays with HDMI inputs. Each source can be routed to any display using the front-panel buttons or the IR Remote Control. The matrix can also be controlled via RS-232 or LAN port. With smart EDID management, make it compatible with most of the HDMI source and sink devices. 

4.5 8x8 HDMI matrix

This 8x8 HDMI matrix routes 8 Ultra HD sources to eight 4K Ultra HD displays with HDMI inputs. Each source can be routed to any display, using the front-panel buttons or the IR Remote Control. The matrix can also be controlled via RS-232, IP interface. With smart EDID management, make it compatible with most of the HDMI source and sink devices.
