1. Font blur can be solved by adjusting the ClearType settings, opening the control panel to enable and calibrating the function to improve the display effect; 2. Calibrating the DPI scaling ratio to ensure that the monitor uses the recommended value, and unifying the multi-screen settings or turning on the system repair options; 3. Updating the graphics card driver and system patches can fix compatibility issues, and check the stability of the external cables.

It is really annoying to blur the font on Windows, especially when you are looking at the screen for a long time. This situation is usually related to system rendering settings, display resolution, or DPI scaling. The good news is that it can be solved in most cases in a few simple steps.

1. Check and adjust ClearType settings

Windows uses ClearType technology to optimize font display, especially for LCD screens. If this function is turned off or not adjusted properly, the font will easily look blurry.

You can do this:

• Open Control Panel → Appearance and Personalization → Adjust ClearType Text
• Check "Enable ClearType" and select the clearest font sample according to the wizard

This process takes about one minute, but it can significantly improve the sharpness of the edges of the text, especially small-font-sized text.

2. Calibrate DPI Scaling

Many monitors now have high resolutions, and the default 100% zoom of Windows may be too small, so many people will adjust it to 125% or higher. However, if an inappropriate zoom ratio is set, or multiple monitors use different zoom settings, the font may be blurred.

Suggested practices:

• Right-click on the desktop → Show settings
• Confirm whether all monitors use the recommended ratio (usually 100%, 125%, 150%) in "Scaling and Layout"
• If you are using an external monitor laptop, try to unify the scaling ratio, or enable "Let Windows try to fix the application scaling problem"

Some programs do not support high DPI scaling and blurring will also occur. At this time, you can right-click the program icon → Properties → Compatibility → Check "Replace high DPI scaling behavior" and set it to "Application" or "System (Enhanced)".

3. Update graphics card driver and system patches

Sometimes font blur is actually caused by system bugs or driver compatibility issues.

Don't underestimate this step. Some display exceptions may be automatically fixed after the update.

• Open Device Manager → Display Adapter → Right-click your graphics card model → Update driver
• Also make sure Windows has the latest update patch installed

In addition, if you are using an external laptop monitor, try changing a cable (such as HDMI to DP), sometimes unstable signal transmission can also lead to rendering abnormalities.

Basically, these common reasons and solutions are all about them. Sometimes the problem may be the superposition of multiple factors, such as improper DPI setting and ClearType closing at the same time. You can check it in order, first adjust ClearType, then check the zoom settings, and finally update the driver, which can usually be done.
