4K HDMI Switch, 3x1
1.0 Introduction
4K HDMI Switch, 3x1 is high performance switch, which can easily switch
three sources to one display. It not only has the key-press-switching
function, but also has intelligent function. With one fixed HDMI cable
(pigtail), this adapter is cost and time saving for consumers.
The 4K HDMI Switch, 3x1 routes high definition video (in multiple
resolutions up to 4Kx2K) and digital audio from any one of the three
sources to display units. All inputs accommodate the connections of the
high definition video sources simultaneously, compatible well for HD-DVD,
SKY-STB, PS3, Xbox360 etc. The output sends high definition audio/video
signals to a high definition display.
1.1 Intelligent function
1. Once the source device is "ON" or plug-in (should stay power-on mode),
the switcher will automatically select this source.
2. Once the source device is turned off or plugged out, the switcher will
select the next power-on source depending on the sequence
The intelligent function is based on power detection. When the
source devices are on the "stand-by mode", the switcher will not
select next power-on source automatically
