The SY-HDS41-18G from SY Electronics is a 4 way HDMI switch that allows four HDMI source devices to share a single HDMI display or projector. The switch provides both automatic and manual switching modes and can be controlled with the front panel, with the included IR remote or via the RS232 interface. The switch is also capable of de-embedding an audio signal and returning it back using the ARC function.
