Yep. Fonts won't all be properly sized. Some image elements may not
line up properly with fonts. In many areas, though, you may not notice

If you have a 16:9 display (i.e. the ratio of the physical length to the
physical height of the display is 16:9), the ratio of the pixel width to
the pixel height is also 16:9 (i.e. 1280x720 or 1920x1080). Same
applies for 4:3 and 4:3, or 5:4 and 5:4, or 16:10 and 16:10, etc.
