What is an HDMI splitter and how does it work?
An HDMI splitter is a device that allows you to connect one HDMI source to multiple HDMI displays. It works by taking the HDMI signal from the source device, such as a Blu-ray player or gaming console, and splitting it into multiple identical signals that can be sent to different displays. This allows you to watch the same content on multiple screens at the same time.
The splitter does not change or modify the HDMI signal in any way, it simply duplicates it and sends it to multiple outputs. This means that the video and audio quality will be the same on all connected displays. HDMI splitters are available in different configurations, such as 1×2, 1×4, and 1×8, which means they can split the signal to 2, 4, or 8 displays respectively.
