  • Right click the desktop and select Display settings from the context menu.
  • On the DISPLAY page of the PC Settings app, click the screen you want to modify under Cusotmize your display. The displays are identified by number.
  • Below Change the size of text, apps and other items, move the slider to the right to increase DPI. The default DPI setting for my display is 125%, and I found increasing the DPI to 150% was sufficient.
  • Once you’re done, click Apply.

You’ll be prompted to log out and sign in again so that Windows can adjust the display for the new DPI settings. This isn’t mandatory, but recommended for the best experience.
