Automatic Input Selection - Example
Laptop PC
The Concept
If there is no other source connected to the transmitter, but the Laptop, HDMI 1 input will be automatically
switched to the TPS output. If the Laptop and the PC are also connected to the transmitter, DVI-D input will
be switched to the TPS output. If the Blu-ray player is connected on the HDMI 2 input, and later the MacBook
is connected on the DP input of the transmitter, it will be switched to the TPS output – independently of the
presence of other video signals.
Settings
▪ TPS output: Set the Autoselect to Enabled. Set Autoselect mode to Priority detect. The priorities are the
following (the lowest number means the highest priority):
Source device
