If your Lenovo laptop screen is flickering, first compare the screen with Task Manager: if Task Manager flickers too, a display-driver issue is more likely; if Task Manager stays steady, an incompatible app is more likely. That Windows diagnostic points you toward the right troubleshooting branch, but it does not by itself prove a component has failed.
The steps below apply to Windows 10 and 11 where noted. Lenovo driver and hardware instructions depend on the exact model, so use the support page for your device rather than guessing a driver, BIOS file, or replacement panel.
Start with when and where the screen flickers
Before changing settings, note whether the flashing began after a Windows or driver update, happens only in one app, appears when you connect or disconnect power, or affects the desktop generally. These clues help you choose what to check next; none alone identifies a failed part.
Use Task Manager to choose the troubleshooting branch
Open Task Manager while the rest of the screen is flickering. Microsoft’s guidance for Windows 10 and 11 is that if Task Manager flickers too, a display-driver problem is more likely. If Task Manager remains steady while other screen content flickers, an incompatible app is more likely. See Microsoft’s screen-flicker troubleshooting guidance.

Try a graphics-driver reset, then choose the right driver action
Microsoft says the reset shortcut may help: press Windows key + Ctrl + Shift + B. The display may briefly go dark or you may hear a beep as Windows attempts to reset the graphics driver. It is a troubleshooting attempt, not a guaranteed fix.
If the flicker began after a recent update, Microsoft recommends rolling back the display driver. If it did not follow an update, updating the driver or uninstalling and reinstalling it may help. Rollback is only an option if Windows has a previous driver available. Microsoft’s instructions and qualifications are in its Windows screen-flicker guide.

Check resolution and refresh rate
Make sure Windows is using a resolution and refresh rate supported by your laptop’s display. In Windows, open Settings > System > Display > Advanced display to view the available refresh rates; exact labels and options can vary by Windows version and hardware. Microsoft explains how to change a monitor’s refresh rate in Windows.

Refresh rate is how many times per second the image refreshes. The correct choice depends on the panel and system: Lenovo documents that some of its computers support dual refresh rates. There is no universal 60 Hz setting that fixes every flickering Lenovo display. Check the options available for your device and use a supported setting. See Lenovo’s adjustable display refresh-rate information.

If the flicker continues after checking the likely app, graphics driver, resolution, and refresh rate, arrange model-specific diagnosis through Lenovo or a qualified technician. Lenovo’s guidance for flickering screens on certain IdeaPad and ThinkPad laptops includes repair or replacement of faulty hardware as a possible escalation. That possibility is not a diagnosis: persistent flicker alone does not establish that the panel is defective.
