7. Auto-switching Function
Under the auto-switching mode, WVG4A will detect the input source and switching
automatically, following some priority principle:
1: Priority of the new connection
When you connect a new valid VGA source to WVG4A, under the auto-switching mode,
WVG4A will switch to this new source.
2: Priority of power reboot or VGA signal removing
When the power is rebooted under the auto-switching mode, WVG4A will detect the 4
VGA input ports, ranging from input1, input2, input3, input4. When it finds a valid VGA
signal, it will switch to this channel.
When the displaying input is removed under the auto-Sw mode, WVG4A will detect the
4 VGA inputs, ranging from input1, input2, input3, input4. When it finds a valid VGA
signal, it will switch to this channel.
Under the auto-switching mode, the video/audio is switching synchronization only, not
separately switching.
