IOGEAR's GCS1794 4-Port HDMI Multimedia KVMP Switch with HDMI connections, Audio and a 2-Port USB 2.0 hub charts a ground-breaking new direction in KVM functionality by combining advanced HDMI and USB 2.0 technology. The HDMI KVM Switch enables effortless control over 4 HDMI devices or computers using a single USB keyboard, USB mouse and single high definition display (720P or 1080P) or HDTV. The HD digital output supports various high definition TV resolutions. Connect your high definition display with HDMI connections, HDTV (flat panel, plasma, DLP, digital TV) and data projectors. The GCS1794 4-Port HD KVMP Switch is HDCP compliant. It is also equipped with IOGEAR's DynaSync which reads and remembers the monitor's parameters (EDID) eliminating any delays or change in video resolution when switching between, or booting computers. The GCS1794 features two USB 2.0 peripheral ports for asynchronously sharing USB devices between your computers. The patented asynchronous switching allows the user to independently switch applications between the connected computers. You can run one application on one computer while running another application on the other. A powered USB hub may be attached to the peripheral ports for added functionality.
