Automatic HDMI Switchers
These Automatic HDMI switchers have the latest audio video technology built-in to auto-detect active input source signals and automatically switch the active input to the output. Unlike other HDMI switchers, these automatic HDMI switchers do not require human interface. Once a signal goes away, the switcher will automatically change to the other input.
NOTE: A few devices like some DVR's, cable/satellite receivers are "always ON" so auto-sensing switchers, like these, need the "always On" devices to be at a lower video input, so it doesn't block other devices. If you have two devices that are always ON you'll need to use the buttons and/or remote control (if they have them) to switch inputs. An Apple TV keeps its HDMI port active even in the sleep state, so auto-switching may not work. Manual switching can still be used.
