6.6.2. HDMI Digital priority
The device always checks the HDMI input first. If there is a valid video signal on the
HDMI input it will be selected. If there is no video signal on the HDMI input the device
checks the DVI-D input. If there is a valid video signal on the DVI-D input it will be
selected. If there is no video signal on the DVI-D input the device checks the VGA input.
If there is a valid video signal on the VGA input it will be selected. If there is no video
signal on the VGA input neither the searching process starts again from the HDMI input.
If the selected input was unplugged or the valid video signal was disappeared the
searching process starts again from the HDMI input. If one of the input ports (e.g. VGA)
was selected - and there is a valid video signal on it - and a valid video signal was
appeared on the HDMI input port
– by connecting or powering on a video source - the
searching process STARTS AGAIN with checking the HDMI input. The previous selected
video input port (VGA) becomes inactive and the privileged one (HDMI) becomes active.
In briefly in case of incoming valid HDMI video signal on the HDMI input, it will always be
selected even if there was an earlier selected video signal.
