How to enlarge Studio/Multiterm icons without compromising the text clarity on a 32 inch 4K monitor?

Dear Studio 2019 experts,

I recently got a 32 inch 4K monitor and found that the icons on the Studio interface are very small.  I tried the ChangeScalingBehavior app, but while the app was able to enlarge the icons and make them easier to see, it also makes the text blurry.  

Is there a way to enlarge the icons without compromising the text quality?  There is a KB article solution#3 that I could try, but I am not sure whether that method would also affect the text clarity and I want to know how to "undo" in case that method did not work out as expected.

Thank you so much for sharing your tips and tricks.
