Fosmon's 3x1 HDMI Switch with 1.8ft Braided HDMI Cable allows you to switch between 3 HDMI inputs and a single display via the built-in HDMI cable. Automatic Input Switching Fosmon's HDMI Switch is built with intelligent switching. This means the switch will automatically detect when input devices power on and off and switch to the corresponding input source. Powered from Connected Devices No power adapter is necessary for this switch to function, as long as the connected devices supply sufficient power through the HDMI cable. For devices that do not output enough power, the included micro-USB cable can be connected to a power source. 4K Support and HDMI Features Up to 4K resolutions at 30fps, 36-bit Deep Color, 3D, and uncompressed/compressed audio formats are some of the newer HDMI features supported. Metallic Alloy Plug The metallic alloy plug on the 1.8ft cable resists corrosion and reduces tarnish. Braided Outer Cable Inner cables are protected from damage by the braided outer cable.
