Windows 10 font blur problem is usually caused by improper display settings, DPI zoom or graphics card driver configuration. The solutions are as follows: 1. Turn on the ClearType text enhancement function to improve text clarity; 2. Adjust the DPI zoom ratio and set it separately for multiple monitors, and enable high DPI zoom behavior if necessary; 3. Update or roll back the graphics card driver and install a stable version; 4. Close some visual effects such as "Show shadows in windows" to optimize rendering effects. It is recommended to check the ClearType and DPI settings first, and if it is invalid, then consider driver or system adjustment.

The problem of blurred fonts on Windows 10 is really annoying, especially when using the computer for a long time, your eyes are prone to fatigue. This situation is usually not because there is a big problem with the system itself, but because of improper display settings, graphics card drivers, or DPI zoom configuration. Below I will start from several common reasons and give you some practical solutions.

1. Check and enable ClearType text enhancement function

ClearType is a technology developed by Microsoft that is specifically used to improve text clarity on LCD screens. It is on by default, but sometimes it is turned off by mistake or needs to be recalibrated.

Operation steps:

• Open Control Panel → Find Display → Click "Adjust ClearType Text"
• Check "Enable ClearType", and follow the prompts to select the clearest text display effect.
• After completion, restart the Explorer or restart the computer to see the changes

This method is effective for most ordinary users, especially when using the laptop's own screen.

2. Adjust DPI zoom settings

If you are using a high-resolution monitor (such as 2K or 4K) and the DPI zoom is not set properly, it is prone to font blur and interface confusion.

The following points can be tried:

• Right-click on the desktop → Display Settings → Select the appropriate zoom ratio in "Scaling and Layout" (usually 100%, 125%, 150%)
• If you have multiple monitors connected, make sure that the zoom settings for each monitor are individually adjusted
• For some applications where they are still blurred, you can right-click the program icon → Properties → Compatibility → Check "Override High DPI Scaling Behavior" and select "Application" or "System (Enhanced)"

Note: Some old software may not support high DPI scaling, and you can select "System (Enhanced)" to force optimization.

3. Update or rollback the graphics card driver

Inappropriate graphics card driver version may also lead to abnormal font rendering. Especially after updating the driver, it suddenly becomes blurred, and it may be that the new version of the driver is not very compatible with your hardware.

Suggested practices:

• Open "Device Manager" → Show Adapter → Right-click the current graphics card → Update driver
• If there is a problem after the latest update, you can also select "Rollback Driver"
• You can also download the latest stable version of the driver to manually install (such as NVIDIA, AMD, Intel)

It is best to restart the computer once after updating the driver to confirm whether the fonts are restored to normal.

4. Turn off visual effects such as "automatic color management"

Sometimes the system turns on some additional color management and visual effects, which will affect the display quality of the font.

You can set it like this:

• Right-click "This Computer" → Properties → Advanced System Settings → Advanced Tab → Performance → Settings
• Uncheck the options "Show shadows in windows" and "Smoothly display web fonts"
• Especially the details such as "displaying file type information in folder prompts" have a great impact.

While these settings seem inconspicuous, they do affect rendering on some devices.

Basically these common ways of dealing with it. You can start with ClearType and DPI scaling, these two are the most direct influencing factors. If it doesn't work, consider driver or system level issues.
