Universal Serial Bus (USB)
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 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 USB-C upstream port (data only) – at bottom. · 1 USB-C downstream port – at Quick Access. · 3 super speed USB 10 Gbps (USB 3.2 Gen 2) Type-A downstream ports- 2 at bottom, 1 at Quick Access.

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 5 V / 3 A 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 Other 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.

Plug-and-Play capability
You can connect the monitor to 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 that 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.

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. · Adjust the ambient lighting around you (such as overhead lights, desk lamps, and
the curtains or blinds on nearby windows) to minimize reflections and glare on the monitor screen. · Use a chair that provides good lower-back support. · Keep your forearms horizontal with your wrists in a neutral, comfortable position while using the keyboard or mouse. · Always leave space to rest your hands while using the keyboard or mouse. · Let your upper arms rest naturally on both sides. · Ensure that your feet are resting flat on the floor. · When sitting, make sure that the weight of your legs is on your feet and not on the front portion of your seat. Adjust your chair’s height or use a footrest if necessary to maintain a proper posture. · Vary your work activities. Try to organize your work so that you do not have to sit and work for extended periods of time. Try to stand or get up and walk around at regular intervals.

Maintenance guidelines
Cleaning your monitor
WARNING: Before cleaning the monitor, unplug the monitor power cable from the electrical outlet. CAUTION: Read and follow the Safety instructions before cleaning the monitor. For best practices, follow the instructions in the list below when unpacking, cleaning, or handling your monitor: · Use a clean cloth that is slightly dampened with water to clean the stand
assembly, the screen, and the chassis of your Dell monitor. If available, use a screen-cleaning tissue or solution suitable for cleaning Dell monitors. · After cleaning the surface of the table, ensure that it is thoroughly dry and free from any moisture or cleaning agent before placing your Dell monitor on it. CAUTION: Do not use detergents or other chemicals such as benzene, thinner, ammonia, abrasive cleaners, alcohol, or compressed air. WARNING: Do not directly spray the cleaning solution or even water directly on the surface of the monitor. Doing so will allow liquids to accumulate at the bottom of the display panel and corrode the electronics resulting in permanent damage. Instead, apply the cleaning solution or water to a soft cloth and then clean the monitor. CAUTION: Using chemicals for cleaning may cause changes in the appearance of the monitor, such as color fading, milky film on the monitor, deformation, uneven dark shade, and peeling of screen area. NOTE: Monitor damages due to improper cleaning methods and the use of benzene, thinner, ammonia, abrasive cleaners, alcohol, compressed air, detergent of any kind will lead to a Customer Induced Damage (CID). CID is not covered under the standard Dell warranty. · If you notice white powder when you unpack your monitor, wipe it off with a cloth. · Handle your monitor with care as a darker-colored monitor may get scratched and show white scuff marks more than a lighter-colored monitor. · To help maintain the best image quality on your monitor, use a dynamically changing screen saver and turn off your monitor when not in use.
