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 properly. 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 may be blank and does 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 U3223QE 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 U3223QE 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.

When you notice screen abnormalities like distortion, clarity, horizontal or vertical lines, color fade, it is always a good practice to isolate the monitor by running the Built-In Diagnostics.

  1. Ensure that the screen is clean (no dust particles on the surface of the screen).
  2. Select OSD items of Self-Diagnostics in Others feature.
  3. Press the Joystick button to start the diagnostics. A gray screen is displayed.
  4. Carefully inspect the screen for abnormalities.
  5. Move the Joystick once again until a red screen is displayed.
  6. Inspect the display for any abnormalities.
  7. Repeat step 5 and step 6 to inspect the display in green, blue, black, and white.
  8. The test is complete when the white screen appears.
  9. To exit, move the Joystick control again.
Note: If you do not detect any screen abnormalities upon using the integrated diagnostic tool, the monitor is functioning properly. Check the video card (GPU) and the computer.
If you notice any abnormalities during Built-In Diagnostics, you may get the monitor repaired or replaced if it is under warranty by contacting Dell Technical Support.

During the LCD Monitor manufacturing process, it is not uncommon for one or more pixels to become fixed in an unchanging state, which is hard to see and does not affect the display quality or usability. For more information, see the Dell knowledge-base article Dell LCD Monitor Pixel Guidelines.
