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 C3422WE 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.

If the monitor does not sense a video signal and is working correctly, it should report a message advising that no video cable was detected:

No Video

Figure 2: No video cable detected

  1. Turn off your monitor and reconnect the video cable: Then turn on both your computer and the monitor.
  2. 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 C3422WE 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. Toggle and hold the Joystick to the up or down or left or right for about 4 seconds until a pop menu appears.
  2. Toggle the Joystick to highlight the Diagnostics icon (far bottom icon), then press the Joystick, and a gray screen appears.
  3. Carefully inspect the screen for abnormalities.
  4. Toggle the Joystick up. The color of the screen changes to red.
  5. Inspect the display for any abnormalities.
  6. Repeat steps 5 and 6 to inspect the display in green, blue, black, white, and text screens.

The test is complete when the text screen appears. To exit, toggle the Joystick up 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.
