Universal Serial Bus (USB) (U2722D/U2722DX)

This section gives you information about the USB ports available on your monitor.

NOTE: Up to 2 A on USB downstream port (port with battery

icon) with BC 1.2 compliance devices; up to 0.9 A on the other 2 USB downstream ports; Up to 3 A on USB-C downstream port (port with icon) with 5 V/3 A compliance devices.

Your monitor has the following USB ports:

• 1 upstream - at rear.

• 4 downstream - 2 at bottom, 2 at rear. Power Charging Port - the ports with battery icon supports fast current charging capability if the device is BC 1.2 compatible. The USB-C downstream port with icon supports fast current charging capability if the device is 5V/3A compatible.

NOTE: The monitor’s USB ports work only when the monitor is on or in

Standby Mode. On in Standby Mode, if the USB cable (A to C or C to C) is plugged in, the USB ports can work normally. Otherwise, follow the OSD setting of USB Charging, if the setting is “On in Standby Mode” then USB work normally, otherwise USB is disabled. If you turn off the monitor and then turn it on, the attached peripherals may take a few seconds to resume normal functionality.

About Your Monitor | 29

Plug-and-Play

You can install the monitor in any Plug-and-Play-compatible system. The monitor automatically provides the computer system with its extended display identification data (EDID) using display data channel (DDC) protocols so the computer can configure itself and optimize the monitor settings. Most monitor installations are automatic; you can select different settings if desired. For more information about changing the monitor settings, see Operating the Monitor.

LCD Monitor Quality and Pixel Policy

During the LCD monitor manufacturing process, it is not uncommon for one or more pixels to become fixed in an unchanging state which are hard to see and do not affect the display quality or usability. For more information on LCD Monitor Pixel Policy, see Dell support site at: https://www.dell.com/pixelguidelines.

Ergonomics

CAUTION: Improper or prolonged usage of keyboard may result in injury.

CAUTION: Viewing the monitor screen for extended periods of time may

result in eye strain.

For comfort and efficiency, observe the following guidelines when setting up and using your computer workstation:

• Position your computer so that the monitor and keyboard are directly in front of you as you work. Special shelves are commercially available to help you correctly position your keyboard.

• To reduce the risk of eye strain and neck/arm/back/shoulder pain from using the monitor for long periods of time, we suggest you to:

1. Set the distance of the screen between 20 to 28 in. (50 - 70 cm) from your

eyes.

2. Blink frequently to moisten your eyes or wet your eyes with water after

prolonged usage of the monitor.

3. Take regular and frequent breaks for 20 minutes every two hours.

4. Look away from your monitor and gaze at a distant object at 20 feet away for

at least 20 seconds during the breaks.

5. Perform stretches to relieve tension in the neck, arm, back, and shoulders

during the breaks.

• Make sure that the monitor screen is at eye level or slightly lower when you are sitting in front of the monitor.

• Adjust the tilt of the monitor, its contrast, and brightness settings.
