How to use

Connect the HDMI source (computer, media player, set-top box or other HDMI device) to the splitter's input port using a high-quality HDMI cable. Connect each display to one of the four HDMI output ports with compatible HDMI cables, then attach the 5 V DC power adapter and switch the unit on. Verify that all connected displays are set to the correct HDMI input and that source resolution is within the splitter’s supported range. If a display does not show the image, check cable seating and try restarting the source and the displays to ensure handshake and EDID negotiation complete correctly.

Recommendations

Use high-quality, high-speed HDMI cables rated for the desired resolution and length to preserve signal integrity. For reliable 4K performance, ensure source device, displays, and cables all support the target resolution and HDMI features. Avoid excessive cable lengths and minimize electromagnetic interference by routing cables away from power lines and large electrical equipment. When deploying in multi-display environments, test each output with the intended display to confirm consistent image quality before final installation.
