To resolve the problem of applying icons, text, or interfaces on Windows 10, try the following methods: 1. Check and adjust the display zoom setting to 100% or the recommended options to ensure that the multi-display zoom is consistent; 2. Right-click to apply shortcuts → Properties → Compatibility → Check "Override High DPI Scaling Behavior" and select "Application" or "System (Enhanced)"; 3. Update graphics drivers and system updates to fix potential compatibility issues; 4. For old programs, manually set their DPI Scaling Mode; 5. Advanced users can enable "System (Enhanced)" mode through the registry. Some software may need to use the above methods in combination or search for specific solutions.

Blurry application icons, text or the entire interface are actually a common problem on Windows 10, especially when some old software or non-high DPI-adapted programs are prone to this situation. The good news is that it can be manually adjusted to improve in most cases.

Check and adjust the display zoom settings

Windows 10's "Show Zoom" function is to make the screen content clearer and easier to read, but if set incorrectly, some applications will become blurred.

• Go to Settings > System > Display
• Find "Change the size of text, apps, etc. items under "Scaling and Layout"
• Try to switch to 100% or other recommended options
• If you are using multiple monitors, make sure that the zoom ratio of each monitor is consistent (some applications do not support normal display across different zoom ratios)

If an app is particularly vague, you can right-click its shortcut → Properties → Compatibility → Check "Override High DPI Scaling Behavior" and select "Application" or "System (Enhanced)".

Update graphics driver and system update

Many graphics display problems actually come from outdated drivers or unpatched system components.

• Open Device Manager and find the graphics card driver (such as NVIDIA, AMD, Intel)
• Right-click to select "Update Driver"
• At the same time, keep Windows updates on and install the latest system updates regularly

Sometimes Microsoft fixes some rendering or compatibility issues with cumulative updates, so it is important to keep the system up to date.

Adjust the DPI settings of the application itself

Some old programs do not adapt to HD screens, and will blur even if the system sets the correct zoom.

How to operate:

• Right-click on the shortcut or executable file of the application → Properties
• Switch to the Compatibility tab
• Click "Change high DPI scaling behavior"
• Set to "Application" or "System (Enhanced)"

This setting is equivalent to telling Windows: Don't automatically scale the program, let it handle it itself or better handle it by the system.

Temporarily enable "System (Enhanced)" mode using the registry (Advanced)

If you find the "System (Enhanced)" option gray-out, it may be because your system version limits the feature. It can be enabled temporarily through the registry:

?? It is recommended to back up the registry before operation.

The steps are as follows:

• Press Win R to enter regedit
• Navigate to path: Computer\HKEY_CURRENT_USER\Software\Microsoft\Windows\DWM
• Create a new DWORD (32-bit) value, named DpiValueScalingPolicy , and set the value to 1
• After logging out and logging back into the system, the "System (Enhanced)" option should be available.

Basically these are the methods. Some fuzzy problems may require a combination of the above methods to solve, especially those that support high resolutions by old or non-native software. If you encounter any problems with the specific application, you can also search for the software name "dpi fix windows 10" separately to find a specific solution.
