EDID (Extended Display Identification Data) is a communication protocol used between HDMI splitters and connected devices. It allows the splitter to receive information about the connected display's capabilities, such as resolution, refresh rate, and audio support.
When the HDMI splitter is connected to multiple displays, it uses the EDID data from each display to determine the optimal settings for all the connected devices. This ensures that the source device can generate the correct signals to match the capabilities of each display.
By using EDID, the HDMI splitter can provide the best possible video and audio experience to each connected display, regardless of their individual capabilities. It also helps prevent compatibility issues and ensures smooth operation when multiple displays are connected to the splitter.
