This 2-port HDMI switch means that you can conveniently switch between two HDMI source devices on a single HDMI-enabled display supporting high definition video up to a 1080p resolution. In situations where a display does not have enough HDMI inputs to accommodate multiple source devices, this switch provides additional high-definition digital inputs & is compatible with HDMI-equipped devices such as Blu-ray & DVD players, high-definition satellite boxes & gaming consoles, including Sony Play Station 4 (PS4) & Xbox ONE. The auto-switching functionality detects when a new device is connected or powered on & will automatically switch to that port. When the device in use is disconnected or powered off, it will switch to the device that was connected first. Alternatively, manual-switching functionality is available for situations where more control is desired Â- simply use the select button on top of the switch to switch back & forth between the two inputs. The power required for operation of this switch is provided from the HDMI source devices, so no separate power adapter is required.
