In auto-switch mode, source selection abides by the following principles:
l New input principle
Upon detecting a new input signal, TL-4X1-HD will switch to this new signal
automatically.
l Power rebooting principle
Once rebooted, TL-4X1-HD will automatically select input 1 as the input source
even if there is no connection in input 1.
l Signal removing principle
When the current display signal is removed, the TL-4X1-HD will detect all input
signals with priority from INPUT 1 to INPUT 4. It will select the first available
source to output.
In manual-switch mode, upon rebooting, the TL-4X1-HD will output the previously
selected source signal.
