It's a small device that lets you take a single HDMI video source, like a DVD player or game console, and send that same video to multiple TVs or monitors. It's like making a copy of the video so everyone can watch it on their own screen.
Can It Make My Screen Bigger Across Multiple TVs?
No, an HDMI splitter can’t do that. It just copies the video, so all screens show the same thing. If you want to stretch your computer screen across several monitors (which is called extending your display), you'll need a different setup, usually involving your computer's graphics card.
So, When Would I Use One?
Showing a sports game on multiple TVs in a sports bar.
Displaying the same educational content in different parts of a classroom.
Any situation where you need the same image on more than one screen.
HDMI splitters are easy to use—just plug in your video source and connect the TVs you want to use. Remember, it’s all about duplicating the video, not extending it.
