You can output video from PCs, game consoles, recorders, etc. to multiple monitors, TVs, projectors, etc. You can choose from two types of output ports: 4 ports and 2 ports. (※ Both have one input port.) Supports simultaneous screen output. With the 4-port type, you can display video on up to 4 displays simultaneously. It uses a metal housing with excellent heat dissipation. It is not only durable but also quickly releases heat. It protects the circuit chip from heat and achieves stable operation. A power adapter is included, so stable power supply is possible even when multiple devices are connected simultaneously. It is compact and space-saving, making it easy to store behind TVs and monitors. It also supports cascade connection. (※ Operation is not guaranteed for all devices. Also, the length of the cable that can be extended varies depending on the HDMI cable and connected devices, so we recommend using a shorter HDMI cable when connecting in cascade.)
