• Always be sure that your monitor is electrically rated to operate with the AC power available in your location.
• Keep the monitor in room temperature. Excessive cold or hot conditions can have an adverse effect on the liquid crystal of the display.
• Do not subject the monitor to severe vibration or high impact conditions. For example, do not place the monitor inside a car trunk.
• Unplug the monitor when it is going to be left unused for an extended period of time.
• To avoid electric shock, do not attempt to remove any cover or touch the inside of the monitor.

• Dell Premium Panel Exchange for peace of mind.
• Optimize eye comfort with a flicker-free screen and ComfortView feature which minimizes blue light emission.
WARNING: The possible long-term effects of blue-light emission from
the monitor may cause damage to the eyes, including eye fatigue, digital eye strain, and so on. The ComfortView feature is designed to reduce the amount of blue-light emitted from the monitor to optimize eye comfort.
* 1 ms is achievable in the MPRT mode and reduces visible motion blur and increases image responsiveness. However, this may introduce some slight and noticeable visual artifacts into the image. As every system setup and every gamer’s needs are different, we recommend that users experiment with the different modes to find the setting that is right for them.

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

WARNING: Improper or prolonged usage of keyboard may result in injury.
WARNING: 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 screen about 20 to 28 in. (50-70 cm) from your eyes.
2. Blink frequently to moisten or rewet your eyes when working with 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/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.
About your monitor | 21
• 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.
• Keep the area under your desk clear of obstructions and cables or power cords that may interfere with comfortable seating or present a potential trip hazard.

Handling and moving the monitor

To ensure the monitor is handled safely when lifting or moving it, follow the guidelines mentioned below:
• Before moving or lifting the monitor, turn off your computer and the monitor.
• Disconnect all cables from the monitor.
• Place the monitor in the original box with the original packing materials.
• Hold the bottom edge and the side of the monitor firmly without applying excessive pressure when lifting or moving the monitor.
• When lifting or moving the monitor, ensure the screen is facing away from you and do not press on the display area to avoid any scratches or damage.
• When transporting the monitor, avoid any sudden shock or vibration to it.
About your monitor | 23
• When lifting or moving the monitor, do not turn the monitor upside down while holding the stand base or stand riser. This may result in accidental damage to the monitor or cause personal injury.

Maintenance guidelines

Cleaning the 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 these instructions in the list below while unpacking, cleaning, or handling your monitor:
• To clean your anti-static screen, lightly dampen a soft, clean cloth with water. If possible, use a special screen-cleaning tissue or solution suitable for the anti­static coating. Do not use benzene, thinner, ammonia, abrasive cleaners, or compressed air.
• Use a lightly-dampened, soft cloth to clean the monitor. Avoid using detergent of any kind as some detergents leave a milky film on the monitor.
• 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.
