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.

Super speed USB 10 Gbps (USB 3.2 Gen2) Device

Transfer speed	Data rate	Maximum power consumption (each port)
Super speed+	10 Gbps	4.5 W
Super speed	5 Gbps	4.5 W
USB 2.0 Device
Transfer speed	Data rate	Maximum power consumption (each port)
Hi-Speed	480 Mbps	2.5 W
Full speed	12 Mbps	2.5 W
Low speed	1.5 Mbps	2.5 W

About Your Monitor

Driver installation

Install the Realtek USB GBE Ethernet Controller Driver available for your system. This is available for download at https://www.dell.com/support under the “Driver and download” section.

Network (RJ45) data rate via USB-C max speed is 1000 Mbps.

NOTE: This LAN port is 1000Base-T IEEE 802.3az compliant, supporting Mac Address (Printed on model label) Pass-thru, Wake-on-LAN (WOL) from standby mode (S3 only) and PXE Boot function, these 3 features depend on BIOS setting and OS version.

RJ45 Connector LED Status (U2722DE Only):

Right LED

Left LED

LED	Color	Description
Right LED	Amber or Green	Speed indicator:
		• Amber On - 100 0 Mbps
		• Green On - 100 Mbps
		• Off - 10 Mbps
Left LED	Green	Link / Activity indicator:
		• Blinking - Activity on the port.
		• Green On - Link is being established.
		• Off - Link is not established.

NOTE: RJ45 cable is non in-box standard accessory.

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.
