[comp.sys.sgi] sgi screen dpi

Dan Karron@UCBVAX.BERKELEY.EDU (04/30/91)

How many dpi is the iris screen, and does it change with different monitors ?

I am using 118 dpi mode TeX fonts, but they don't look quite right.

Does anyone have a mf mode setting that they like for the iris screen ?

I will post an improved (slightly) dvitex when I get it working the way
I like !

I finally got mf to work, so I can make fonts galore in all sizes for every
printer and screen I have modedefs for Metafont.


Cheers!

For the 4D series on a 19" monitor the resolution is just a hair under 96 dpi.
With a 14" monitor on a PI the resolution is about 108 dpi.

When in doubt get out a tape measure, measure the scanned area of the monitor
and divide by the number of pixels.  Our monitors are adjusted so they have
the same scanned area.

  While we are on the subject, could you use:

   getgdesc(GD_XMMAX);   /* Horizontal size of the screen in millimeters */
   getgdesc(GD_YMMAX);   /* Vertical size of the screen in millimeters */
   getgdesc(GD_XPMAX);   /* Horizontal size of the screen in pixels */
   getgdesc(GD_YPMAX);   /* Vertical size of the screen in pixels */

  to get the screen resolution.  How does the machine know the monitor size?
