Connecting USB Devices 
The following section covers connecting USB devices. The LCD monitor provides an upstream and two 
downstream USB connections. 
Upstream 
You can connect the LCD monitor’s upstream USB port to your PC’s USB port and use the LCD monitor as a 
USB hub. The following explains how to connect the upstream USB port to your PC: 
1.  Connect one end of the USB cable to the LCD monitor’s upstream USB port. 
2.
  Connect the other end to the PC’s USB port. 
 
 
Downstream 
The two downstream USB ports connect USB devices, such as USB keyboards, scanners and mice, directly to 
your LCD monitor. 
Connect the USB device’s USB cable to one of the LCD monitor’s downstream USB ports. 
 The upstream USB port must be connected to your PC for the downstream USB ports to function. 
Power Management System 
The LCD monitor complies with the VESA DPMS power management proposal. The VESA DPMS proposal 
provides power saving modes by detecting the horizontal or vertical sync signal. 
When the LCD monitor is in power saving mode or detects an incorrect timing, the monitor screen will be 
blank and the power LED indicator starts blinking.
