# Re: [NTLK] Screen size and resolution

Screen DPI has little (nothing, in fact) to do with the resolution of a
screen image. DPI is strictly for printing. The fact that Apple advertised
the Newton as having 100 DPI (200 and 2100) screen resolution speaks more to
the density of the pixels than anything else. It's like saying a monitor
with a dot pitch of 26 has a higher DPI than a screen with a dot pitch of
28.

The physical resolution is the only thing that matters on a screen. If the
Newton is 480x320, then that's the size image that will fit on the display.

Hope that helps.

Subject: [NTLK] Screen size and resolution

I am in the process of creating a graphic for a Newton Book I am putting
together and got stumped on figuring out the size and resolution of the
Newton screen. My graphic program, Fireworks, wants me to put in both the
physical size and resolution of the image.

The FAQ lists the screen size as 480x320 but does not give the physical size
of the screen or the DPI of the screen.

Measuring the screen with a ruler comes out with about 5x3-5/16. Doing the
math shows 480/5 = 96DPI while 320/3.3125 = 96.6DPI. Is 96DPI the correct
screen resolution?
