An HDMI splitter is a device that allows you to distribute a single HDMI signal to multiple displays simultaneously. It works by taking the HDMI input signal and splitting it into identical output signals, ensuring each connected display receives the same high-quality audio and video content without any degradation.

While HDMI splitters are primarily designed for distributing signals to multiple displays, some models also offer signal boosting capabilities, allowing you to extend HDMI signals over longer distances. Look for HDMI splitters with built-in signal amplification or consider pairing them with HDMI extenders or baluns to transmit signals over greater distances reliably.

When selecting an HDMI splitter, consider factors such as the number of outputs required, HDMI version compatibility (e.g., HDMI 2.0 for 4K resolution), maximum supported resolution and refresh rate, audio support (e.g., Dolby Atmos, DTS:X), and additional features like remote control or automatic switching. It's essential to ensure compatibility with your devices and the specific requirements of your setup.

Yes, you can use an HDMI splitter to mirror your computer screen to multiple monitors or TVs simultaneously. By connecting the HDMI splitter to your computer's HDMI output port and then connecting multiple displays to the splitter's output ports, you can duplicate the computer's screen onto each connected display. This is useful for presentations, gaming setups, digital signage, and other scenarios where you need to display the same content across multiple screens simultaneously.
