5. USE
Switching between connected HDMI devices
The Connect 420 UHD™ allows you to choose which HDMI source is
displayed on the TV. If you turn on one of the HDMI sources, it will
automatically switch to the correct input. If multiple HDMI sources are turned
on, the Connect 420 UHD™ will automatically switch to the HDMI source that
was activated last. If you want to select another HDMI source, please use the
remote control or the "Select" button on the front.
Note: Automatic switching must be supported by the HDMI source. If it is not
supported, you should manually select the appropriate HDMI source.
