Cables to Go 40011 is a 4x2 HDMI matrix switch that allows you to connect up to four HDMI source devices to two HDMI displays. This means you can easily switch between different sources, such as a Blu-ray player, game console, or computer, without having to constantly unplug and replug cables. The matrix switch also supports resolutions up to 1080p, so you can enjoy high-quality video and images.

To use the matrix switch, simply connect your HDMI source devices to the input ports and your HDMI displays to the output ports. Then, use the front panel buttons or the included remote control to select the source device you want to display. The matrix switch also has a built-in power supply, so you don't need to worry about using an external power adapter.
