The Gefen ToolBox 4x1 Switcher for HDMI 1.3 is a compact and lightweight alternative to rack-mounted HDMI 1.3 switchers. It allows up to four set-top boxes, DVD players, or other HDTV devices to be connected to one HDTV display. When two or more switchers are connected together, they can be used to support many more hi-def sources such as Blu-Ray players, satellite set-top boxes, and all types of HDMI displays. Features include support for hi-def, deep color resolutions up to 1080p@60 Hz combined with advanced lossless digital audio formats for pristine sound reproduction
