A diagnostic test helps determine if the Dell monitor is normal when faced with a blank screen, blurry image, flickering or other abnormalities.
Verify that the monitor is working correctly by running a diagnostic test if you experience the following symptoms.
- 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 gets 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 hear the windows chime, but the monitor screen is blank.
Self-Test Feature Check
Your Dell P2425HE monitor provides a self-test feature check that allows you to check if the monitor is functioning properly. When the monitor is connected to the computer but the screen stays dark, run the monitor self-test by following these steps:
- Turn off the computer and the monitor.
- 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.
- 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 scrolls through the screen.
- This box also appears during normal system operation, if the video cable becomes disconnected or damaged.
- Turn off the monitor and reconnect the video cable.
- Turn on the computer and the monitor.
If the screen remains blank, check the video card (GPU) and computer, because the monitor is functioning properly.
Built-In Self-Test or Built-In Diagnostics
Your Dell P2425HE monitor has an integrated diagnostic tool. Hardware diagnostic helps determine if the screen abnormality issue is with the monitor or the video card on your computer.
If you observe any screen anomalies, you should isolate the monitor by performing the built-in diagnostics (BID).
- Ensure that the screen is clean (no dust particles on the surface of the screen).
- Select OSD items of Self-Diagnostics in Others feature.
- 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.
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.
During the manufacturing process, it is not uncommon for one or more pixels to get stuck in an unchanging state. Such pixel issues are hard to see and do not affect the display quality or usability. Learn more about Dell Display Pixel Guidelines.

|
| Unable to switch back to native resolution (1920 x 1080) after Picture by Picture is turned off. | Dell P2425HE supports Picture by Picture (PBP) mode. Picture by Picture (PBP) mode is two side-by-side images with each image that is displayed at 2560 x 1440 resolution. When the monitor is connected to a computer using HDMI and PBP mode is turned off, the monitor may display images at the lower resolution (2560 x 1440) rather than automatically switching to the native resolution (1920 x 1080). |

| Light leak from the monitor | The monitor appears to have light leaking from the edges in a dark room. | This is the normal behavior of the monitor. Dell consumer monitors are tested under 150-lux ambient lighting (similar to typical office lighting). Dell UltraSharp and Gaming monitors are tested with tighter criteria of 70-lux ambient lighting (dimly lit room, but not dark). Learn more about Troubleshooting Light Leakage or Light Bleeding on a Dell Monitor or Laptop LCD Screen. |
| Color variation on the corners of the monitor | The monitor appears to have color variation on the corners of the screen. | The optimal viewing position for the monitor is from the center of the screen. Dell P2425HE monitor uses a curved IPS panel, the corners of the screen may appear slightly yellowish or pinkish, especially when viewing in a dark room. This is normal IPS panel behavior and typically does not affect the overall viewing performance.
|
