Text blur problem is mainly caused by incompatibility in DPI scaling or improper font rendering. The solutions are as follows: 1. Adjust the system DPI scaling ratio to standard values and enable "replace high DPI scaling behavior" for specific programs; 2. Enable ClearType technology and select the best font style; 3. Modify program compatibility settings, try to run as an administrator or enable compatibility mode; 4. Update Windows system and graphics card drivers to optimize display effects. In most cases, text blurring can be effectively improved by combining the above methods.

The problem of fuzzy text in Windows applications is actually quite common, especially some old software or non-high DPI-friendly programs. Although this problem does not affect the function, it does feel uncomfortable. The main reasons are usually the DPI scaling settings are incompatible or the font rendering is incorrect.

Check and adjust DPI zoom settings

This is one of the most common reasons. If your monitor is a high-resolution screen (such as 2K or 4K), the default zoom ratio may cause some programs to display abnormalities.

• Open Settings > System > Display
• In the Scaling & Layout section, try setting the scaling to 100%, 125%, or other standard values
• If an app is particularly vague, right-click the app's shortcut or executable → Properties → Compatibility → Check "Override High DPI Scaling Behavior" and select "Application" or "System (Enhanced)"

Different options may have different effects. You can try a few more to see which one is the clearest.

Enable ClearType font smoothing technology

ClearType is a font rendering optimization technology provided by Windows that can significantly improve text display quality.

• Open Control Panel → Find "Adjust ClearType Text" or enter "cleartype" directly in the search bar
• Check "Enable ClearType"
• Then follow the prompts to select the font style you look the clearest (don't skip this step)

This setting affects all programs that support ClearType, including browsers and Office software.

Modify program compatibility settings

Some old software is not optimized for modern high DPI monitors, and manual intervention is required at this time.

• Right-click on the Program → Properties → Compatibility Tab
• Check the following two options:
  • Alternative to high DPI scaling behavior
  • Run as an administrator (and sometimes it works)
• Click App to save settings and restart the program to see if there is any improvement

You can also try running the program in "compatibility mode", such as Windows 7 or XP SP3, which is helpful to some old software.

Update graphics card driver and system patches

Sometimes the problem lies in the graphics driver or the system itself. Make sure your system and graphics drivers are up to date:

• Update Windows: Settings → Update & Security → Windows Update
• Update the graphics card driver: You can access the graphics card official website (NVIDIA, AMD, Intel) through the device manager or through the graphics card official website (NVIDIA, AMD, Intel)

Especially for laptop users who use integrated graphics cards, they can often see obvious improvements in display effects after updating the driver.

Basically these are the methods. Start with DPI settings and ClearType enabled, and then cooperate with program compatibility adjustments, which can be solved in most cases. Not every method applies to all programs, but trying a few more combinations usually leads to the right solution.
