I had the same problem and this worked for me.
1. Open a Windows Command Prompt by searching for “command prompt” in the Windows Start Menu
2. In the Command Prompt, run the command:
matlab -cefdisablegpu
3. Wait for MATLAB to open and observe if the blurriness persists
To make it so that MATLAB always starts like this:
1) Locate your MATLAB shortcut (often on the desktop) and right click the icon
2) Select “Properties” from the menu
3) In the “Properties” window, locate the “Target” field on the “Shortcut” tab
4) Without modifying the path currently in the “Target” field, add a space to the end followed by
-cefdisablegpu
If a space does not separate the flag from the file path, this will not work
5) Select “Apply” and then “OK” to save these changes
