Note: The USB upstream port assignment is not updated until the current video input is changed. To
immediately change the USB upstream port, hold down the INPUT button on the front of the monitor
until the shortcut menu appears, then select the USB port.
About DisplaySync Pro
The NEC MultiSync PA Series displays feature an integrated USB 2.0 hub with 3 downstream (outputs)
and dual upstream (input) USB ports.
The dual upstream USB ports allows the integrated USB hub to switch between two different host
PCs. Devices connected to the USB outputs on the monitor will be switched between the two up-
stream ports. This switching can be linked to the video input selection on the monitor so that as the
video input is switched from one host PC to the other, any USB devices connected to the monitor,
such as a keyboard and mouse, will also be switched along with the video.
This feature allows the monitor to function as a KVM (Keyboard Video Mouse) switch. The INPUT
button on the front of the monitor can be used to quickly switch between different video inputs. The
attached USB devices will follow the current video input selection.
Note: Once devices are switched to another host PC, they will no longer be accessible on the original
PC until the input is switched back.
Important: Extreme care should be taken when using the DisplaySync Pro with certain USB de-
vices such as flash memory sticks and hard drives, as data can be lost or corrupted if the device is
switched between upstream ports while write operations are being performed. Always use the device
"eject" function on the host PC before switching upstream ports with these types of devices.
The USB panel controls the DisplaySync Pro
settings.
MultiProfiler allows the mapping relationship of the
two upstream (inputs) USB ports to the video inputs
to be configured.
The current video input is indicated by a red arrow.
In the example shown on the left, the current video
input, DVI-2, will select upstream port USB1. When
the video input is changed to the D-SUB (VGA)
input, the upstream port USB2 will be selected and
all connected USB devices will be switched over.
The setting can also be used to immediately switch
the upstream USB port for the current video input.
This is useful, for example, when you want to change
the connected USB devices between two host PCs
without changing the video input.
