How to use

Connect the HDMI source device (such as a media player, laptop, or set-top box) to the splitter's HDMI input. Attach HDMI cables from the splitter's outputs to each target display. Connect the supplied power adapter to the splitter and a mains outlet, then power on the source and displays.

Recommendations

Use high-quality HDMI cables of appropriate length to minimize signal degradation, and verify that both the source device and displays support the intended 4K resolution and HDMI 1.4b features. For long cable runs or advanced EDID management needs, consider active cables or signal extenders. Place the splitter in a ventilated area and avoid exposure to extreme temperatures or moisture.
