If your Dell monitor has a blank or black screen, fuzzy or blurry image, flickering, distorted or any other screen abnormalities, running a diagnostic test helps determine if the Dell monitor is functioning normally. To learn more about diagnostic options on a Dell monitor, see the Dell knowledge-base article: How do I run diagnostics on a Dell monitor?

It is always essential to isolate the monitor while troubleshooting your computer for the following scenarios:

  • No Power - Your computer is not powering ON or showing any signs of power.
 
  • No POST - Your computer is not showing any indication of activity, the screen might be blank and will not display the Dell logo during start-up.
 
  • No Video - You are unable to see any display on the screen, able to hear the windows chime but no display is seen.

Your Dell P2422H Monitor provides a self-test feature check that allows you to check whether 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 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 the video cables (VGA, DVI, HDMI, or DisplayPort) from the back of the computer.
  3. Turn on the monitor.
  4. Turn off your monitor and reconnect the video cable: Then turn on both your computer and the monitor.
  5. If your monitor screen remains blank after you use the previous procedure, check your video card (GPU) and computer, because your monitor is functioning properly.

Your Dell P2422H monitor has a built-in 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 observe any screen anomalies, you should isolate the monitor by performing the built-in diagnostics (BID).

Dell P2422H Joystick Control
Figure 4: Dell P2422H Joystick Control

  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 Main Menu.
  3. Move the joystick button to select Others → Self-Diagnostic to initiate the self-diagnostic process.
  4. When initiated, a gray screen appears. Inspect the screen for abnormalities.
  5. Switch the joystick button. The color of the screen changes to red. Inspect the screen for abnormalities.
  6. Repeat step 5 and inspect the screen when it displays the colors green, blue, black, and white followed by the on-screen text.
  7. The test is complete when the text screen appears. To exit, tap the joystick button 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.

When you close and then reopen the lid on a laptop, the Connecting and Configuring Displays (CCD) feature in Windows automatically reverts the display mode to the last active selection. This behavior is by design in Microsoft Windows.

Switch to the display mode that you want after you close and reopen the laptop screen manually:

  1. Press the Windows logo key + P on the keyboard
  2. Select Second screen only or Projector only mode
