A)The workaround for this would be the following steps
1)Right-Click on the MATLAB executable icon, Go to Properties 2)Under the Compatibility menu, check the option “Disable display scaling on high DPI settings” 3)Now Run MATLAB. It should no longer rescale when you open SIMULINK.
B)However the text and icons in the toolstrip might still be too small to read. 1)The size of the text and the menus is not customizable. 2)You need to reduce the resolution to increase the font size. One way to enforce this would be to add a call to an executable or some kind of Windows command line script that does this in your “startup.m”. When you open up MATLAB, the executable will run and change the resolution of the desktop. 3)You can then create a file called “finish.m”. This file is always run when you close MATLAB. You can add another call to the executable or the Windows command line script and instruct it so that it will reset the desktop resolution to the default value or whatever the increased resolution was.
