OREI UHD-404R Switch, split, and amplify your HDMI signal with the Switcher/Splitter. The UHD-404R matrix has four HDMI inputs and four HDMI outputs, so you can switch between four input source devices and send the signal simultaneously to four 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 UHD-404R supports full 3D/2D, Ultra HD resolutions up to 4K @ 60Hz, and HD resolutions up to 1080p, Deep Color up to 48 bit, and all audio channels up to 7.1. Note that you don't have to have four inputs and four 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. The convenient remote control is included to switch between inputs on both displays.
