Dell Inspiron 15 3520 – Screen Flickering Issue After Windows Update

Hi, I’m having an issue with my Dell Inspiron [Model Number] after the latest Windows update. The screen started flickering intermittently, especially when I open multiple applications or use certain programs. I’ve tried restarting, checking the display drivers, and even rolling back the update, but the issue persists. Has anyone experienced this problem and found a solution? Any suggestions would be really helpful!

Thank you in advance!

Hi,

The screen flickering issue after a Windows update is likely caused by driver conflicts or software settings. Since the LCD BIST passed, the hardware seems to be fine. Here are some steps you can try:

1. Update Graphics Drivers

  • Go to Device Manager (Windows + X > Device Manager).
  • Expand Display Adapters and right-click your GPU (Intel, NVIDIA, or AMD).
  • Select Update Driver and choose Search automatically for drivers.
  • Alternatively, download the latest driver from Dell Support for your Inspiron 15 3520.

2. Adjust Refresh Rate

  • Open Settings > System > Display.
  • Scroll to Advanced display settings and check your refresh rate.
  • Set it to the recommended rate (e.g., 60Hz or 120Hz depending on your display).

3. Disable Hardware Acceleration

  • For specific apps (like browsers), turn off hardware acceleration in their settings.

4. Perform a Clean Boot

  • Open Run (Windows + R), type msconfig, and press Enter.
  • In the Services tab, check Hide all Microsoft services and click Disable all.
  • Go to the Startup tab and open Task Manager to disable startup apps.
  • Restart and check if the flickering persists.

5. Roll Back Display Driver

  • In Device Manager, right-click your display adapter and select Properties > Driver > Roll Back Driver (if available).

If none of these steps resolve the issue, it could be a bug introduced by the recent update. You may want to report the issue to Microsoft or Dell Support for further assistance.

Could you perform LCD BIST and let me know if the issue still occurs there?

  1. Disconnect External Devices: Remove any connected peripherals, such as USB devices or external monitors.
  2. Clean the Screen: Ensure the LCD screen is clean and free of dust particles.
  3. Start the BIST Test:
    • Press and hold the "D" key on the keyboard while turning on the computer.
    • Continue holding the "D" key until the screen displays a series of solid colors: black, white, red, green, and blue.
  4. Inspect the Screen: Carefully check for abnormalities such as flickering, lines, or discoloration during the test.
  5. Exit the Test: Press the "Esc" key to exit the test when done.

Results Analysis:

  • No Abnormalities: If the screen displays the colors without issues, the problem may be related to the video card (GPU), drivers, or cable connections.
  • Abnormalities Detected: If you notice issues like lines or color distortions, the LCD panel may need repair or replacement.

    Test system with AC adapter disconnected.

    Please update me on your findings. If the problem persists, feel free to share additional details, and we’ll be happy to assist further.

Thank you for the detailed steps. I followed the instructions and performed the LCD BIST test. The screen displayed the colors without any abnormalities, so it seems like the issue might be related to the GPU, drivers, or cable connections. I also tested the system with the AC adapter disconnected, and the issue persists. I’ll check for driver updates and recheck the cable connections. If the issue continues, I’ll reach out with additional details. Thanks again for your help!

Before continuing down the AI generated list, uninstall whatever update you applied.  Does that solve the problem?

I’ve had a similar issue with screen flickering after a Windows update. Have you tried disabling hardware acceleration in the apps where it happens most? Sometimes that helps. Also, maybe check if Dell has any updated display drivers or a firmware update on their support site—it could be specific to your laptop model.
