5. Advanced operation
5.7 USB
About USB
By default, USB will be enabled. This will allow the connected PC to communicate directly over USB with
the internal Nio 5MP LED Display processor.
By disabling USB, communication between the internal Nio 5MP LED Display processor and the con-
nected PC will not be possible. This does not disable the USB hub and still allows to make use of the
display’s USB downstream connectors and any external devices connected to it (keyboard, mouse, ...).
Please note that a connection from a PC USB downstream connector to the display’s USB upstream
connector is required to be able to use this functionality.
Enabling the USB endpoint is only recommended when you are using a non-Barco dis-
play controller. If you are using a Barco display controller, this communication will au-
tomatically be done over the connected video cable(s).
To enable/disable USB:
1. Bring up the OSD main menu.
2. Navigate to the Con fi guration > Connectivity menu.
3. Enter the USB submenu.
4. Select Enabled/Disabled as desired and con fi rm.
5.8 DPMS mode
About DPMS mode
Enabling the Display Power Management System (DPMS) mode on your display will optimize its diagnos-
tic lifetime by automatically switching off the backlight when the display is not used for a speci
fi ed period
of time. By default, DPMS mode is enabled on your display, but it also needs to be activated on your
workstation. To do this, go to the “Power options properties” window of your workstation.
Barco recommends setting DPMS activation after 20 minutes of non-usage.
When DPMS mode is enabled on your display, an additional OSD power saving function
becomes available: hibernate. Please refer to "Hibernate", page 22 for more information
on hibernation and how to enable this function.
To enable/disable DPMS mode on your display:
1. Bring up the OSD main menu.
2. Navigate to the Con fi guration > Power Management menu.
3. Enter the DPMS Mode submenu.
4. Select Enabled/Disabled as desired and con fi rm.
