Fixing QR Code Display Issues on Windows 10
Scanning QR codes on Windows 10 can sometimes be frustrating when the codes display incorrectly. The scrambled pixelated codes fail to scan properly, providing no route to the information they should contain.
Fortunately, while irritating, the problem is solvable with a few troubleshooting techniques. We’ll explore some methods to restore QR code functionality on Windows 10 in this tutorial.
Check for Windows and Driver Updates
One of the first things to try is updating your Windows 10 operating system. Microsoft frequently releases patches and fixes in Windows Updates that address bugs and problems.
To check for the latest Windows 10 updates:
- Open Settings and go to Update & Security > Windows Update.
- Click Check for updates. Windows will search for the latest updates and display available ones ready to download and install.
- Review the list of optional updates and install any related to displays or graphics.
- Restart your computer after installing updates.
It’s also a good idea to update your display drivers. Buggy, outdated drivers can cause rendering issues that corrupt QR codes. Updating to the latest driver from your graphics card manufacturer may fix display problems.
You can update drivers manually via Device Manager or let Windows find driver updates automatically through Windows Update. For detailed instructions, see our guide on [how to update display drivers on Windows 10].
Verify the QR Code Itself
Assuming Windows is up-to-date, the next step is examining the QR code itself. Confirm the code is properly generated without defects:
- Check the QR code size – smaller QR codes become pixelated when enlarged.
- Ensure the code has sufficient contrast between dark and light modules.
- Verify the code does not contain an over-abundance of complex patterns, clustering, or customization. These can hinder scanners.
- Confirm the code resolves to an active URL and does not link to a dead or invalid destination.
Proper QR code creation is vital for scannability. Our guide on [QR code best practices] covers creating optimal codes. Regenerating the code using these tips may provide better results.
Try a Different Scanner
If the QR code checks out, try scanning it using another app or device. The Windows 10 built-in camera scanner or individual app scanners may have difficulties reading certain codes.
- Use the camera scanner in a mobile app like Google Lens to scan the QR code.
- Download a dedicated QR scanning app for Windows 10 like QR Code Reader and use its scanner instead.
- On another device like a phone, install an app like QR Code Reader and attempt scanning the code directly from the problematic Windows screen.
A different scanner app may have better optics and decoding algorithms able to extract the QR code accurately.
Apply Optional Intel Graphics Updates
Some Windows users report success after installing optional graphics driver updates from Intel specifically for QR code display problems .
To find optional graphics updates:
- Open Windows Update settings and click "View optional updates."
- Look for any optional updates mentioning your Intel graphics card under the "Driver updates" section.
- Download and install graphics updates one by one and check if the QR code scanning improves.
These specialized Intel updates seem to resolve QR code scanner glitches for some configurations.
Use Windows BSOD QR Codes
When all else fails, an unlikely solution involves triggering QR codes from Windows Blue Screen of Death errors. Intentionally forcing repeated BSOD crashes generates QR codes that provide diagnostics on why your PC is malfunctioning .
While drastic, examining BSOD dump files and QR codes may uncover wider system issues impacting QR code displays. Proceed with caution.
Additional Troubleshooting Tips
A few other ideas to try for stubborn QR code display problems:
- Check display or monitor cables. Loose connections can impact rendering.
- Boot into Windows Safe Mode and test QR codes there. Software conflicts could cause problems.
- Try toggling Windows display acceleration settings to see if that impacts decoding.
- Update monitor drivers and firmware from your display manufacturer.
- Test QR codes on an external display connected to your PC.
If you continue having difficulties scanning QR codes, seek additional help from [Microsoft Community forums] or Windows troubleshooting sites. Displaying QR codes properly involves many components, so further investigation may be required in complicated cases.
