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 will help determine if the Dell monitor is functioning normally. To learn more about diagnostic options on a Dell monitor, refer to 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 U2722D 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. The 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, one of the dialogs shown below will continuously scroll through the screen.
- This box also appears during normal system operation if the video cable becomes disconnected or damaged.
- 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 controller and computer, because your monitor is functioning properly.
Your Dell U2722D 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.
- Ensure that the screen is clean (no dust particles on the surface of the screen).
- Press and hold Up or Down or Left or Right direction for four seconds until a menu appears on the screen.
- Using the Joystick control, highlight the Diagnostics option and press the Joystick button to start the diagnostics. A gray screen is displayed.
- Observe if the screen has any defects or abnormalities.
- Toggle the Joystick once again until a red screen is displayed.
- Observe if the screen has any defects or abnormalities.
- Repeat steps 5 and 6 until the screen displays green, blue, black, and white colors. Note any abnormalities or defects.
- The test is complete when a text screen is displayed. To exit, toggle the Joystick control again.
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.
