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. About your monitor | 35 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. 36 | About your monitor • 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. monitor screen at or below eye level monitor and keyboard positioned directly in front of the user wrists relaxed and flat feet flat on the floor About your monitor | 37 Handling and moving your display 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. 38 | About your monitor • When lifting or moving the monitor, do not turn the monitor upside down while holding the stand base or stand riser.

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.

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. Operating the monitor | 103 • • 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 VolP/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. The audio playback performance is the same on either of the audio path. For UC conference applications, Dell Technologies recommends selecting the default Echo Cancelling Speakerphone audio path. NOTE: When you select DELL C2422HE/DELL C2722DE/DELL C3422WE audio path, ensure that the Echo Cancelling Speakerphone volume is set to medium or high, otherwise the DELL C2422HE/DELL C2722DE/DELL C3422WE maximum volume may sound soft as it is limited by the Echo Cancelling Speakerphone volume. For example, when the Echo Cancelling Speakerphone volume is at 50%, and the DELL C2422HE/DELL C2722DE/ DELL C3422WE volume is set to 100% also may have the same sound level as the former.
