The HDMI 4x2 Matrix Selector Switch allows up to four HDMI audio/video devices to be independently switched to two HDMI monitors, HDTVs or projectors. This matrix selector switch delivers deeply rich, uncompressed digital video and true life surround sound audio with zero signal loss. It supports 3D when connected to 3D enabled devices, supports high definition resolution 1080p, as well as supports DDWG standard for HDMI compliant monitors.
