What is an HDMI splitter and how does it work?
An HDMI splitter is a device that allows you to connect a single HDMI source to multiple HDMI displays or devices. It works by taking the HDMI signal from the source device and splitting it into multiple identical signals, which are then sent to each connected display or device. This allows you to watch the same content on multiple screens at the same time.
However, it’s essential to note that not all HDMI splitters are created equal. Some may not support all HDMI features, such as 4K resolution or HDR, and may not work with all devices. Additionally, some HDMI splitters may introduce signal degradation or latency, which can affect the quality of the image or audio.
What are the main negatives of using an HDMI splitter?
