Difference between HDMI splitter and HDMI switch


The HDMI splitter receives the signal from one device and splits the signal onto multiple devices or screens.

For Example: If you have a laptop and are watching a movie, and you want to display the movie on your TV and living room projector, then you can use a splitter to have the same display from one main device to several HDMI-supported devices.


The HDMI switch combines multiple signals from HDMI devices to one display device.

For example: If you have multiple cameras and want to share all their video images on one screen, you would use an HDMI switch. HDMI cables from all cameras are plugged into the HDMI switch input section. After that, you will use an HDMI cable to connect the switch’s HDMI output section and your display device.
