Section 6. Operation of UMX-OPT-TX150R
6.6.3. DVI-D Digital priority
The device always checks the DVI-D input first. 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 HDMI input. 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 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 DVI-D input. If the selected
input was unplugged or the valid video signal was disappeared the searching process
starts again from the DVI-D 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 DVI-D
input port
– by connecting or powering on a video source - the searching process
STARTS AGAIN with checking the DVI-D input. The previous selected video input port
(VGA) becomes inactive and the privileged one (DVI-D) becomes active. In briefly in case
of incoming valid DVI-D video signal on the DVI-D input, it will always be selected even if
there was an earlier selected video signal.
