					Plug-and-Play   
					You can install the monitor in any Plug-and-Play-compatible computer. The monitor   
					automatically provides the computer 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 necessary. For more information about changing the   
					
					LCD monitor quality and pixel policy   
					During the LCD monitor manufacturing process, it is normal 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 about LCD Monitor Pixel Policy, see

					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, or shoulder pain from using   
					the monitor for long periods of time, it is recommended to:   
					• Set the distance of the screen between 20 in. to 28 in. (50 cm - 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 ft away for at   
					least 20 seconds during the breaks.   
					• Perform stretches to relieve tension in the neck, arm, back, and shoulders   
					during the breaks.   
					• Ensure 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, ensure that the weight of your legs is on your feet and not on the   
					front portion of your seat. Adjust your chair 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.

					monitor.   
					For best practices, follow these instructions 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 anti-   
					static 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 dark-colored monitor may get scratched and   
					show white scuff marks more than a light-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.

					monitor back to computer through USB, this selection is required for VolP/   
					UC conference applications. Audio Recording and Playback works in this   
					selection.   
					• 
					DELL S2422HZ or S2722DZ audio path is where audio streams through   
					HDMI/DP/DP alternate mode. Microphone is not supported in this selection.   
					This selection is suitable for Audio Playback only.   
					Audio Playback performance is same for both audio path options. Under normal

					WARNING: Before you begin working on the following steps, follow the   
					
					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 following dialog box appears on the screen (against a black background),   
					when the monitor cannot sense a video signal and is working correctly. While   
					in self-test mode, the power LED remains white. Depending upon the selected   
					input, one of the following dialog boxes will continuously scroll through the   
					screen.

					computer and the monitor.   
					If your monitor screen remains blank after you use the previous procedure, check your   
					video controller and computer, as your monitor is functioning properly.   
					Built-in diagnostics   
					Your monitor has a built-in diagnostic tool. It helps you determine if the screen   
					abnormality that you are experiencing is an inherent problem with your monitor, or with   
					your computer and video card.   
					To run the built-in diagnostics:   
					1. Ensure that the screen is clean (no dust particles on the surface of the screen).   
					2. Press and hold Button 4 for four seconds, a menu appears on the screen.   
					3. Select the Built-in diagnostics   
					option. A gray screen is displayed.   
					4. Observe if the screen has any defects or abnormalities.   
					5. Press Button 1 on the front panel again. The color of the screen changes to red.   
					6. Observe if the screen has any defects or abnormalities.   
					7. Repeat steps 5 and 6 until the screen displays green, blue, black, and white   
					colors. Note any abnormalities or defects.   
					The test is complete when the text screen is displayed. To exit, press Button 1 again.   
					If you do not detect any screen abnormalities upon using the built-in diagnostic tool,   
					the monitor is functioning properly. Check the video card and computer.
