The following could be the possible reasons for blurry text:
- Graphics drivers
- Screen Resolution
- Change the application’s high-DPI scaling mode:
1.1) Right Click on “MATLAB” icon, select “Properties” -> “Compatibility” -> “Change high DPI settings”.
1.2) In the High DPI scaling override area, select Override high DPI scaling behavior, and then try one of the following options:
1.2.1) Application – Disable all Windows scaling settings and only use the app developer's setting. This option was called Disable display scaling on high DPI settings in previous versions of Windows.
1.2.2) System – Overrides the program’s DPI settings and makes it run like it would on a low-DPI display. On a high-DPI display, this will make the program appear blurry.
1.2.3) System (Enhanced) – Windows will try to use enhanced DPI scaling for this program. As a result, some programs will display with crisp text on high-DPI displays. This won't work for all programs.
2. Alternatively, you can also fix scaling for apps in Settings and scale the size between 100% - 500%.
