4K HDMI selector with 5 inputs and 1 output, easy switching with remote control. I bought it and tried it, but it didn't work properly. The lamp lights up, so I think it should be usable. It is unclear whether the problem is due to the environment or a defect in the product itself. The main unit, remote control, cables, and instruction manual are all included. Due to the questionable operation, please consider it as a junk item. We do not offer support for malfunctions after purchase. Please understand this before purchasing. - Model: HDMI SWITCH 5 TO 1 - Resolution: 4K (3840x2160) 30Hz - Input Ports: 5 - Output Ports: 1 - Accessories: Remote control
