Operating the Monitor
Contrast (Sub)
Adjust the contrast level of the picture in PIP/PBP
Mode.
Press the
button to increase the contrast and press
the
button to decrease the contrast.
USB Selection
Allows you to set the USB upstream port for the input
signals (DP, HDMI 1, and HDMI 2), thus the monitor's
USB downstream port (eg. keyboard and mouse) can be
used by the current input signals when you connect a
computer to either one of the upstream ports.
When you use only one upstream port, the connected
upstream port is active.
NOTE:
To prevent data damage or loss, before changing
USB upstream ports, make sure that NO USB storage
devices are in use by the computer connected to the
monitor’s USB upstream port.
