Also, there are two types of HDMI Matrices those that use HDMI cables and those that use network cables. HDMI Matrix allows multiple displays to share multiple sources and makes for a great way to keep the different HDMI signal sources hidden with only the HDMI Matrix in view which can also be remote controlled. That way you can switch between multiple sources and displays at a time hence it is sometimes referred to as HDMI Matrix Switch or Switcher. This is somewhat like a hybrid of HDMI Switch and HDMI Splitter in the sense that it connects multiple displays to multiple sources. There is 4×1 or 4 in 1 out which means the same thing, or 3×1, 5×1 and so forth all indicating the number of devices that you can connect to the display unit like a TV for example. You can even have an HDMI Switch with a remote control so you can switch easily with the press of a button. You can simply plug your gaming console and media player into one HDMI Switch and choose which one you want to use each time instead of having to remove one and put the other every time you want to switch sources. While all the signals from each source are active, the HDMI Switch is able to serve as an external HDMI port if you don’t have enough HDMI ports on your display. On the other hand, HDMI Switch is able to take HDMI signals from different sources but outputs only one at a time. You can have a 1×2 or 1×4 HDMI splitter which means you’re taking an HDMI signal from one device and distributing it to two or four displays respectively What is an HDMI Switch? That way, the HDMI Splitter sends out the same signal to all the display units. So in this case, they all receive the same 1080p video signal but the HDMI Downscaler brings that of the lower resolution display to 720p. To solve this, you can easily use an HDMI downscaler between the HDMI Splitter and the lowest resolution. In other words, the HDMI signal will output signal at the lowest common denominator (if you have displays with different resolutions, let’s say a 720p and two 1080p displays, then they will all receive the video signal with a resolution of the lowest among them all, which in this case is 720p) and this is due to EDID (Extended Display Identification Data) handshake which requires the splitter to send out an identical signal to all the displays.

For this reason, powered network cable HDMI is the best option because it has a repeater that boosts the signal for it to travel a longer distance. You can use a network cable HDMI splitters to take a video signal to numerous displays that might not be in the same location, for example, if you want to be able to watch contents from your TV box on TVs in different rooms then the cable has to travel a relatively long distance. There are two types of HDMI Splitter the HDMI Cable Splitter which is the basic form and Network Cable HDMI Splitter which is more ideal for more complex installations and connections over much longer distances especially the powered ones.
