Re: [NTLK] DPI on a newton?

There are two things here that people tend to confuse.
There is the resolution of the display and the output of the display adapter.

The display adapter could be anything. It depends on which adapter is in the machine and what driver is talking to it.

The native resolution of any screen, however, is fixed.
There are a certain number of pixels in a given area - period.

The Newton has a 320 x 480 pixel area.
Each pixel is 0.245mm square.
They have a 0.015mm gap between them.
Active area is 124.8mm x 83.2mm

Pixel + Gap = 0.245 + 0.015 = 0.26mm

1 inch = 25.4mm

25.4mm / 0.26mm = ~97.69 DPI
