1. What Causes Screen Flickering in Windows 10 and 11

Before jumping into fixes, it helps to know why this happens. Display flickering in Windows 11 and Windows 10 users usually comes down to one of these:

  • An outdated or corrupted display driver (the most common cause)
  • A buggy app running in the background
  • The wrong refresh rate for your monitor
  • HDR being switched on when your screen doesn’t handle it well
  • A loose cable connection between your PC and monitor
  • Rarely, a faulty graphics card or monitor

The problem often shows up right after a Windows update, a driver update, or after installing new software. That timing is actually a big clue—remember when your flickering started, because it will help you narrow down the fix.

It’s also worth noting that flickering is different from other display glitches, like seeing horizontal lines on your laptop screen or a screen that stays completely white on startup. Those symptoms usually point to a failing panel or cable rather than the driver and software causes covered here, so it’s worth ruling out flickering specifically before moving on.

2. Step 1: Run the Task Manager Flicker Test

This is the single most useful test for screen flickering Windows 10 Task Manager troubleshooting, and it takes ten seconds.

  1. Press Ctrl + Shift + Esc at the same time to open Task Manager directly.
  2. Leave it open on your screen — you don’t need to click anything inside it.
  3. Watch closely to see whether the Task Manager window itself flickers along with the rest of the screen.

Here’s how to read the result:

  • If Task Manager flickers too, along with everything else, the issue is likely your hardware or display driver.
  • If everything else flickers but Task Manager stays steady, the issue is almost certainly caused by an app running on your PC.

This one test tells you which section of this guide to focus on first, so don’t skip it.

3. Fix 1: Check Your Monitor and Cables

It sounds too simple, but loose cables cause a surprising number of screen-flickering cases—especially on desktop PCs with external monitors.

  • Unplug the video cable from both the monitor and the PC, then plug it back in firmly.
  • If you have a spare cable (HDMI, DisplayPort, or VGA), swap it in and test again.
  • If you have access to a second monitor, connect it to rule out a bad screen.

If a different cable or monitor fixes the problem, your original monitor or cable is likely damaged. At that point, it’s worth contacting the manufacturer about a repair or warranty claim rather than continuing to troubleshoot software.

Note that this is different from a PC that won’t turn on at all — if your computer shows no signs of power, that points to a hardware fault well beyond the display, not a flickering issue.

4. Fix 2: Set the Correct Refresh Rate

Your refresh rate is how many times per second your monitor redraws the image, measured in Hertz (Hz). Standard monitors run at 60Hz, while gaming monitors can go up to 144Hz, 240Hz, or higher. If Windows is set to a refresh rate your monitor can’t properly handle, flickering is a common result.

How to change refresh rate in Windows 11 (and Windows 10):

  1. Press Windows key + I to open Settings.
  2. Go to System > Display.
  3. Click Advanced display (Windows 11) or Advanced display settings (Windows 10).
  4. Open the Refresh rate dropdown and try a lower value.

Test each option for a minute or two. If the flickering stops at a lower rate, stay there. If it doesn’t improve, go back to your monitor’s officially recommended refresh rate, which is usually printed in the manual or on the manufacturer’s website.

5. Fix 3: Turn Off HDR

HDR (High Dynamic Range) can cause flickering on monitors that don’t fully support it, or when combined with certain games and video apps. If you turned on HDR recently and the flickering started around the same time, this is worth testing first.

How to disable HDR to fix screen flickering in Windows 11:

  1. Open Settings > System > Display.
  2. Find the HDR toggle and switch it off.
  3. Restart the affected app or game and see if the flickering stops.

You can always turn HDR back on later once you’ve confirmed it isn’t the cause.

6. Fix 4: Update or Roll Back Your Display Driver

Display driver issues are behind most cases of flickering screens Windows 10 and 11 users experience, especially right after a Windows update.

If the problem started after a recent update, roll back the driver:

  1. Type Device Manager into the taskbar search box and open it.
  2. Expand Display adapters.
  3. Right-click your graphics adapter and choose Properties.
  4. Go to the Driver tab and select Roll Back Driver, then confirm.
  5. Restart your PC.

If rolling back isn’t available, try updating instead:

  1. Open Device Manager and expand Display adapters again.
  2. Right-click your adapter and choose Update driver.
  3. For the newest version, visit your PC or graphics card manufacturer’s website directly (NVIDIA, AMD, or Intel).

As a last resort, uninstall the driver completely:

  1. In Device Manager, right-click your display adapter and choose Properties.
  2. Check the box for Delete the driver software for this device.
  3. Click OK, then restart. Windows will usually reinstall a basic driver automatically.

This section covers flickering screens with NVIDIA graphics cards, AMD graphics screen flickering, and Intel HD graphics flickering equally—the steps are the same regardless of your graphics card brand. If you’re not sure which brand or model you have, you can check your PC’s graphics card and specs before searching for the right driver. And if you notice your fans spinning up and Desktop Window Manager using high GPU in Task Manager around the same time as the flicker, that’s another sign the driver needs attention.

7. Fix 5: Uninstall the App That’s Causing the Flicker

If your Task Manager test showed the flicker was app-related, or if you noticed it start right after installing new software, the fix is usually to update or remove that app.

  1. Try to remember exactly when the flickering began and what you installed around that time.
  2. Check the app’s official website for a newer version. If one exists, install it — this often solves the problem right away.
  3. If no update is available, remove the app temporarily:
    • Press Windows + I to open Settings.
    • Click Apps.
    • Scroll to find the app, click it, and select Uninstall.
  4. Restart your computer and check if the flickering has stopped.

You can always reinstall the app later once the developer releases a fix.

8. Fix 6: Turn Off Hardware Acceleration

Some apps — especially browsers like Chrome and video players — use your graphics card to render content faster. This is called hardware acceleration, and it can sometimes conflict with your display driver and cause flickering, particularly a flickering screen when using Chrome on Windows 10.

In most Chromium-based browsers:

  1. Open the browser’s Settings.
  2. Search for “hardware acceleration” or look under System.
  3. Turn off “Use hardware acceleration when available.”
  4. Restart the browser.

If the flickering stops, you’ve found your cause. You can leave acceleration off or turn it back on once your display driver is fully updated.

9. Fix 7: Run an SFC Scan for Corrupted System Files

Corrupted system files can occasionally cause display problems. Windows has a built-in tool to check for and repair this.

  1. Type cmd in the taskbar search, right-click Command Prompt, and choose Run as administrator.
  2. Type sfc /scannow and press Enter.
  3. Wait for the scan to finish — this can take several minutes.
  4. Restart your PC once it’s done.

This is a low-effort fix worth trying if nothing else has worked yet.

10. Fix 8: Test in Safe Mode

Safe Mode loads Windows with only the essential drivers and no startup apps. If your screen doesn’t flicker in Safe Mode, that confirms the cause is a driver or an app — not your hardware.

How to boot into Safe Mode:

  1. Open Settings > System > Recovery.
  2. Under Advanced startup, click Restart now.
  3. After the restart, choose Troubleshoot > Advanced options > Startup Settings > Restart.
  4. Press 4 or F4 to boot into Safe Mode.

If the flickering disappears here, go back through the driver and app fixes above with more confidence.

11. Fix 9: Reseat Your Graphics Card

If you’ve tried everything above and the flickering continues — especially on a desktop PC — a loose graphics card connection could be the cause.

Quick test: If your motherboard has a built-in display port, move your monitor cable from the graphics card to the motherboard. If the flickering stops, your dedicated graphics card is likely the problem.

To reseat the card:

  1. Power off your PC completely and unplug it.
  2. Open the case and carefully remove the graphics card from its slot.
  3. Reinsert it firmly until it clicks fully into place.
  4. Close the case, reconnect everything, and power on.

Only attempt this if you’re comfortable opening your PC. If flickering continues after reseating, the card itself may be faulty and worth a warranty check.

12. Fix 10: Create a New Windows User Profile

Sometimes a corrupted user profile is behind persistent display glitches. Creating a new profile can rule this out.

  1. Press Windows key + I to open Settings.
  2. Go to Accounts > Family & other users.
  3. Click Add account (Windows 11) or Add someone else to this PC (Windows 10).
  4. Follow the setup wizard, then sign in to the new profile and check for flickering.

If the new profile doesn’t flicker, you can move your files over and start using it as your main account.

13. Special Cases: Battery, External Monitor, Dual Monitor, and Startup Flickering

A few situations deserve their own quick notes:

  • Screen flickering only on battery in Windows 11: This usually points to power-saving settings lowering your GPU performance. Try plugging in and testing — if it stops, adjust your power plan under Settings > System > Power.
  • External monitor flickering Windows 10: Follow the cable and refresh rate fixes above first, since external displays are especially sensitive to both.
  • Dual monitor setup flickering: Make sure both monitors are set to compatible refresh rates in Display settings, since mismatched rates between two screens can cause flicker.
  • Flickering screen on startup in Windows 11: This almost always points to a driver loading issue—the driver rollback or reinstall steps in Fix 4 are the best place to start. If instead your laptop shows a white screen on startup and never gets past a blank display at all, that’s a separate issue and points more toward a boot or hardware fault than a flicker.

14. FAQ: Screen Flickering Windows 10 and 11

Is screen flickering a hardware or software issue? It can be either, but software issues (drivers, apps, HDR, refresh rate) are far more common. The Task Manager test in Section 2 is the fastest way to tell which one you’re dealing with.

Can outdated drivers cause screen flickering? Yes. An outdated, corrupted, or freshly updated display driver is the single most common cause of flickering screen Windows 10 and 11 issues.

Does HDR cause screen flickering in Windows 11? It can, especially on monitors that don’t fully support HDR or when running certain games and video apps. Turning HDR off is a quick way to test this.

Can loose cables cause screen flickering? Yes, especially on desktop PCs with external monitors. Reseating or replacing the video cable solves this more often than people expect.

Why does my screen flicker only in certain apps? This usually points to hardware acceleration or a compatibility issue within that specific app, rather than your whole system. Try turning off hardware acceleration in that app first.

How do I fix a flickering screen on Windows 10 without reinstalling Windows? Work through the fixes in order: Task Manager test, cables, refresh rate, HDR, display driver, and problem apps. The vast majority of cases are solved before you’d ever need to reinstall Windows.

Why does my screen flicker only on battery? Power-saving settings often reduce GPU performance to save battery, which can trigger flickering on some laptops. Adjusting your power plan usually fixes this.

If flickering isn’t your only display problem, these guides can help too:

A Final Note

Screen flickering feels alarming the first time it happens, but as you’ve seen, it’s almost always fixable without professional repair. Start with the Task Manager test, work through the fixes in order, and you’ll likely have a stable, flicker-free screen again in under 30 minutes.
