Best HDMI Splitters
As an Amazon Associate I earn from qualifying purchases.
An HDMI splitter takes one source and sends the same signal to multiple displays at once, which is useful when you want a game or movie showing on both a projector and a TV, or across rooms. For a home theater the priority is a splitter that duplicates 4K HDR and surround audio cleanly, without downscaling the picture or dropping the sound. This guide compares HDMI splitters for home theater use, covering bandwidth for 4K and high frame rates, HDR passthrough, and how each handles displays with different capabilities. We flag models that manage audio and resolution matching well, so you can mirror a single source to several screens while keeping the full quality your setup is meant to deliver.
