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

  • The monitor must 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 must be set at eye level when you are sitting comfortably. Adjust your chair height or the height of the monitor to achieve this.

A diagnostic test helps determine if the Dell monitor is normal when faced with a blank screen, blurry image, flickering or other abnormalities.

Verify that the monitor is working correctly by running a diagnostic test if you experience the following symptoms.

  • 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 gets 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 hear the windows chime, but the monitor screen is blank.

Self-Test Feature Check

Your Dell P2424HT monitor provides a self-test feature check that allows you to check if the monitor is functioning properly. When the monitor is connected to the computer but the screen stays dark, run the monitor self-test by following these steps:

  1. Turn off the 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, DVI, HDMI, DisplayPort, or USB-C cable) from the back of the computer.
  3. Turn on the monitor. A 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, the dialog box will continuously scroll through the screen.
  4. This box also appears during normal system operation, if the video cable becomes disconnected or damaged.
  5. Turn off the monitor and reconnect the video cable.
  6. Turn on the computer and the monitor.

If the screen remains blank, check the video card (GPU) and computer, because the monitor is functioning properly.

Built-In Self-Test or Built-In Diagnostics

Your monitor has a built-in diagnostic tool that helps you determine if any screen abnormality you experience 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 the Joystick button to launch the OSD Menu Launcher and move the Joystick up to open Main Menu.
  3. Move the Joystick to select Others > Self-Diagnostic to initiate the selfdiagnostic process.
  4. When initiated, a gray screen appears. Inspect the screen for abnormalities.
  5. Toggle the Joystick. The color of the screen changes to red. Inspect the screen for abnormalities.
  6. Repeat step 5 to inspect the display in green, blue, black, white, and text screens.
  7. The test is complete when the text screen appears. To exit, switch the Joystick 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.

During the manufacturing process, it is not uncommon for one or more pixels to get stuck in an unchanging state. Such pixel issues are hard to see and do not affect the display quality or usability. Learn more about Dell Display Pixel Guidelines.
