What causes text, buttons, dialog boxes and screens to be missing, cut off, or overlapped?

In order for buttons, screens and dialog boxes to display correctly, the font size needs to be set to 100% or 96 dpi.

Windows 10

Go to Start > Control Panel > Display > choose Smaller – 100% (default). This uses a default of 96 pixels per inch.

Hint: You can make everything on your screen larger by choosing a lower screen resolution, such as 800 x 600. Windows 10 also includes a Magnifier Tool to temporarily enlarge a portion of the screen.

Windows Vista

Go to Start > Control Panel > Appearance and Personalization > Personalization > Adjust Font Size (DPI). Choose Default Scale (96 dpi).

Windows XP

Right-click the Desktop > Properties > Settings tab > Advanced > General tab > DPI Setting. Choose Normal Size (96 dpi).
