If the Dell monitor has a blank screen, blurry image, flickering, or other screen abnormalities, then 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 P3223QE 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 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 computer 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 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 P3223QE 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).

  1. Press the joystick button to launch the OSD main menu.
  2. Move the joystick up or down to select Others option in the menu, and press the joystick button again to select.
  3. Move the joystick up or down to select Self-Diagnostic option in the menu and press the joystick button again to select.
  4. Press the joystick button again to start the diagnostics.
  5. A gray screen is displayed.
  6. Observe if the screen has any defects or abnormalities.
  7. Press the joystick button again until a red screen is displayed.
  8. Observe if the screen has any defects or abnormalities.
  9. Repeat steps 7 and 8 until the screen displays green, blue, black, and white colors. Note any abnormalities or defects.
  10. The test is complete when the text screen appears. To exit, press the joystick control 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.
