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 to Run a Diagnostic Test 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 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 U2422HE 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:
- Turn off both your computer and the monitor.
- 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.
- Turn on the monitor.
- Turn off your monitor and reconnect the video cable, then turn on both your computer and the monitor.
- 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 U2422HE 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.
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.

- Switch and hold the Joystick to the up or down or left or right for about 4 seconds until a pop menu appears.
- Switch the Joystick to select the Diagnostics icon, then press the Joystick, and a gray screen appears.
- Carefully inspect the screen for abnormalities.
- Switch the Joystick up. The color of the screen changes to red.
- Inspect the display for any abnormalities.
- Repeat step 5 and step 6 to inspect the display in green, blue, black, white, and text screens.
- The test is complete when the white screen appears.
- To exit, switch the Joystick up again.
Note: If you do not detect any screen abnormalities upon using the built-in 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.
