Q16: Why I cannot automatically
switch to the connected input
source after daisy chain over
USB-C?
Ans.: It's because your primary monitor
connects to more than one input
source at the same time. When
you use the primary monitor to
the notebook with USB-C, and
also daisy chain to the secondary
monitor.
Once the notebook goes into
standby mode, if you want to
show the content from HDMI or
DisplayPort, please press
change the signal input source.
Q17: What can I do if there is no signal
on my monitors when daisy-
chaining them together?
Ans.: There are two ways to try to
resolve the no signal issue:
1) On the monitor with the
DisplayPort Signal output, press
the OSD (On-Screen Display)
menu button. Select Input and
PC
to

change Auto to OFF and then
select DP (DisplayPort) input.
This will allow the signal to pass
through to the next monitor.
Both monitors should begin
displaying properly.
2) Disconnect the video cable
between the first and second
monitor, then connect the second
monitor directly to the computer.
On the second monitor press the
OSD menu button, select Input,
change Auto to OFF, and select
DP input. Reconnect the first and
second monitors to the computer
and the daisy chain function will
be enabled.

Press , change Auto to OFF
