Hello,
Thank you for posting your question on Microsoft community forum.
Windows allows you to use scaling to increase the size of text and other items on the screen. When you use scaling in this way, Windows magnifies the size of text and UI(User Interface) elements to the scale you choose. Each account on a computer has a separate setting for scaling.
I would suggest you to try using steps provided in this article and check if it helps.
