Switch, split, and amplify your HDMI signal with the OREI HD-402 Switcher/Splitter. The HD-402 matrix has four HDMI inputs and two HDMI outputs, so you can switch between two input source devices and send the signal simultaneously to two displays. No setup or special configuration is required, simply connect the input device(s) and output device(s) and start using it! The built-in auto adjusting amplifier ensures no signal loss. The built-in amplifier will then regenerate the HDMI signal before sending it to the outputs. The HD-402 supports full 3D/2D 4K/2K Ultra HD resolution, up to 1080p HD resolutions and all audio channels up to 7.1. Note that you don't have to have four inputs and two outputs to use this device. You can use just the switching function if you only have one display or just the splitter function if you have only one input. Convenient remote control is included to switch between inputs on both displays.
