Remark

¹ Software controls the blue light emission by reducing excessive blue light, resulting in a more yellow tone. 2 Color gamut describes the availability of colors in the display. Various standards were developed for specific purposes. 100% corresponds to the full color space as defined in the standard. 3 NTSC stands for National Television Standards Committee, which developed a color space for the television system that is used in the United States. 4 sRGB is a standard red, green, and blue color space that is in use on monitors, printers, and the World Wide Web. 5 DCI-P3, short for Digital Cinema Initiatives – Protocol 3, is a color space used in digital cinema that encompasses a wider range of colors than the standard RGB color space. 6 Adobe RGB is a color space created by Adobe Systems that encompasses a broader range of colors than the standard RGB color model, particularly in the cyans and greens.

DDPM is a software application that helps you set up and configure the Dell monitors and peripherals. Some of its features include:
1. Adjusting the monitor On-Screen Display (OSD) settings such as brightness, contrast, and resolution without needing to use the joystick on the monitor.
2. Arrange multiple applications on your screen by placing them into a template of your choice using Easy Arrange. 3. Assign applications or files to the partitions of Easy Arrange, save the layout as a profile, and restore the profile automatically
with Easy Arrange Memory when needed. 4. Connect the Dell Monitor to multiple input sources and manage these video inputs using the Input Source feature. 5. Customize each application with its own distinct color mode using the Color Preset feature. 6. Replicate software application settings from one monitor to another identical monitor using the Import/Export application
settings feature. 7. Receive notifications and update the firmware and software. 8. If the display supports the Keyboard Video Mouse (KVM) feature, you can set up and share the keyboard and mouse across
connected computers using the USB KVM option. 9. Also, if the display supports the Network KVM feature, then you can share the keyboard and mouse across computers on the
same network and transfer files between them. 10. A macOS version of DDPM software is also available for your monitor. For the list of displays that support DDPM macOS version,
see the knowledge base article 000201067 at https://www.dell.com/support. NOTE: Some features of the DDPM mentioned above are available only on select monitor models. For more information about DDPM, and the recommended computer configuration to install it, go to https://www.dell.com/support/ddpm.

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

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.
