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:

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

• Blink frequently to moisten your eyes or wet your eyes with water after prolonged usage of the monitor.
• Take regular and frequent breaks for 20 minutes every two hours.
• Look away from your monitor and gaze at a distant object at 20 feet away for at least 20 seconds during the breaks.

• 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.

- 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.

If the USB cable and the HDMI or DP cable are connected from monitor to the computer, two audio paths named DELL C2422HE/C2722DE/C3422WE and Echo Cancelling Speakerphone (C2422HE/C2722DE/C3422WE) from the monitor will show in the Sound setting interface. The C2422HE/C2722DE/C3422WE monitor would show options for two audio paths supported in the monitor.

• Echo Cancelling Speakerphone (C2422HE/C2722DE/C3422WE) audio path is where audio streams through USB. This is either through USB-C to USB-C cable or USB-A to USB-B cable. As the microphone path streams from monitor back to PC through USB, this selection is required for VoIP/UC conference applications. Audio Recording and Playback will work under this selection.
• DELL C2422HE/C2722DE/C3422WE audio path is where audio streams through HDMI/ DP/ DP alternate mode. Under this selection, there will not be microphone support. This selection is suitable for Audio Playback only.

Audio Playback performance would be the same for either audio path selection. Under normal Playback with USB-C to USB-C/USB-A to USB-B and/or for UC conference applications, default selecting the Echo Cancelling Speakerphone (C2422HE/C2722DE/C3422WE) audio path is recommended.

NOTE: If you select DELL C2422HE/C2722DE/C3422WE audio path, please ensure that the Echo Cancelling Speakerphone (C2422HE/C2722DE/C3422WE) volume is set to medium or high. Else, the DELL C2422HE/C2722DE/C3422WE maximum volume may sound soft because it is limited by the Echo Cancelling Speakerphone (C2422HE/C2722DE/C3422WE) volume. For example, when the Echo Cancelling Speakerphone (C2422HE/C2722DE/C3422WE) volume is at 50%, and the DELL C2422HE/C2722DE/C3422WE volume is set to 100% will have the same sound level as the former.

Troubleshooting

WARNING: Before you begin any of the procedures in this section, follow the Safety Instructions.

Self-test

Your monitor provides a self-test feature that allows you to check whether your monitor is functioning properly. If your monitor and computer are properly connected but the monitor screen remains dark, run the monitor self-test by performing the following steps:

1. Turn off both your computer and the monitor.
2. Unplug the video cable from the back of the computer. To ensure proper Self-Test operation, remove all digital and the analog cables from the back of computer.
3. Turn on the monitor.

The floating dialog box should appear on-screen (against a black background), if the monitor cannot sense a video signal and is working correctly. While in self-test mode, the power LED remains white. Also, depending upon the selected input, one of the dialogs shown below will continuously scroll through the screen.

No DP Cable The display will go into Standby Mode in 4 minutes. www.dell.com/C24/27/3422XE or No USB-C Cable The display will go into Standby Mode in 4 minutes. www.dell.com/C24/27/3422XE

1. This box also appears during normal system operation if the video cable becomes disconnected or damaged.

2. Turn off your monitor and reconnect the video cable; then turn on both your computer and the monitor.

If your monitor screen remains blank after you use the previous procedure, check your video controller and computer, because your monitor is functioning properly.

Built-in diagnostics

Your monitor has a built-in diagnostic tool that helps you determine if the screen abnormality you are experiencing is an inherent problem with your monitor, or with your computer and video card.
