Power lock function

About the power lock function
By enabling the power lock function, the NIO 2MP LED Display is forced to remain switched on. This
means that it can't be switched to stand-by mode until the power lock function is disabled again.
To enable/disable the power lock function:
1. Bring up the OSD main menu.
2. Navigate to the Configuration > User Interface > Controls menu.
3. Enter the Power Lock submenu.
4. Select Enabled/Disabled as desired and confirm.

USB

About USB
By default, USB will be enabled. This will allow the connected PC to communicate directly over USB with
the internal NIO 2MP LED Display processor.
By disabling USB, communication between the internal NIO 2MP 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 Configuration > Connectivity menu.
3. Enter the USB submenu.
4. Select Enabled/Disabled as desired and confirm.
