Attaching the stand

The standard monitor stand is detached when the monitor is shipped from the factory. To learn how to attach the standard monitor stand, see the user manual of the Dell E2723HN monitor.

To learn how to set up any other monitor stand or monitor arm, see the setup guide of the product.

CAUTION: Do not remove the monitor from the packaging box before attaching the stand.

Ergonomics

Where you put your monitor is almost as important as what model you buy.

  • The monitor should be directly in front of you, at an arm’s length away (between 20-40 inches from your eyes).
  • The top edge of the screen should be set at eye level when you are sitting comfortably. Adjust your chair height or the height of the monitor to achieve this.
  • 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.

Connecting your monitor to the computer

To connect your Dell E2723HN monitor to your computer:

WARNING: Read and follow Safety Precautions When Working with Electronic and Electrical Equipment.
  1. Turn off the computer.
  2. Connect the power cable to the monitor.
  3. Connect the video cable (VGA or HDMI) between the computer and the monitor.
    NOTE: Setting up the monitor with a Dell docking station? Learn How to Connect and Set Up a Docking Station With a Dell Laptop.

Dell E2723HN monitor orientation must always be in landscape mode. This includes any wall-mounted monitors, monitors on a stand, or a monitor arm. In a multiple monitor setup, Dell E2723HN should not be rotated either to 180° (landscape) or 90° (portrait).

CAUTION: Dell E2723HN setup must comply with the recommended panel orientation and working angle only. Setting up the monitor in an orientation that is not recommended may damage the monitor and/or cause a safety hazard.

When setting up your Dell E2723HN monitor, ensure that the monitor front panel buttons are at the bottom right.

Using the tilt

WARNING: The monitor should not be rotated 180° (landscape). The monitor should not be orientated at 90° (portrait).
NOTE: This is applicable for a monitor with a stand. When any other stand is bought, see the respective stand setup guide.

With the stand that is attached to the monitor, you can tilt the monitor for the most comfortable viewing angle.

If the Dell monitor has a blank screen, blurry image, flickering, or other screen abnormalities, running a diagnostic test helps determine if the Dell monitor is functioning normally.

If you are experiencing any of the following symptoms, verify that the monitor is working correctly by running a diagnostic test.

  • Your computer does not turn on or shows any sign of power.
  • Your computer does not show any indication of activity, the screen is blank and does not display the Dell logo during start-up.
  • Your computer is stuck at the Dell logo screen or does not respond to any keys during start-up.
  • You cannot see any display on the screen.
  • You can hear the windows chime but no display is seen.

Self-Test Feature Check

Your Dell E2723HN monitor provides a self-test feature check that allows you to check if the monitor is functioning properly. If the monitor and computer are properly connected but the monitor screen remains dark, run the monitor self-test by following these 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, disconnect the video cable (VGA or HDMI) from the back of the computer.
  3. Turn on the monitor.

    If the monitor is working correctly, it detects that there is no signal and one of the following messages appears. While in self-test mode, the power LED remains white.

    Self-Test for VGA input
    Figure 4: Self-Test for VGA input

    Self-Test for HDMI input
    Figure 5: Self-Test for HDMI input

    NOTE: This box also appears during normal computer operation, if the video cable is disconnected or damaged.
  4. Turn Off your monitor, reconnect the video cable, and then turn on your computer and the monitor.

If the monitor screen remains blank after you use the above procedure, check your video card (GPU) and computer, because your monitor is functioning properly.

Built-In Self-Test or Built-In Diagnostics

Your Dell E2723HN monitor has an integrated diagnostic tool. It helps to determine if the screen abnormality you are experiencing is a problem with the monitor or with the video card on your computer.

If you notice any screen abnormalities, it is a good practice to isolate the monitor by running the built-in diagnostics (BID).

NOTE: You can run the built-in diagnostics only when the video cable is unplugged and the monitor is in self-test mode.
  1. Turn off both your computer and the monitor.
  2. Ensure that the screen is clean (no dust particles on the surface of the screen).
  3. Disconnect all video cables from the monitor.
  4. Turn on the monitor. The monitor then goes into the self-test mode.
  5. Press and hold the Exit button (button 4) for four seconds to enter the OSD lock/unlock menu.

  7. Carefully inspect the screen for abnormalities.
  8. Press the Up button (Button 1) on the back cover again. The color of the screen changes to grey.
  9. Inspect the display for any abnormalties.
  10. Repeat step 6 and 7 to inspect the display in red, green, blue, black, white, and text pattern screens.

The test is complete when the text pattern screen appears. To exit, press the Up button (Button 1) again.

If you do not detect any screen abnormalities in the diagnostics test, the monitor is functioning properly. Check the video card (GPU) and the computer.

If you notice any abnormalities in the diagnostics test, contact Dell Technical Support for repair options.
