To make things exciting, many LCD 1280x1024 monitors have square pixels.

I'd go with the assumption that monitors do have square pixels, and thus the
view ratio == resolution ratio. Then supply a "special" option to compensate
for the known oddball cases, of which 1280x1024 on a 4x3 monitor is the only
obvious one.

Well, there's the case of 800x600 being blown up to fullscreen on a 16:9
display, too, and stretching like mad. There's no good way of finding this
out. The best you can do is capture the resolution at start-up, before mode
switch, and assume it's square.

Note that most CRT monitors have separate width/height adjustment for the
image, so individual users may have a different adjustment, too.

Cheers,

  Hi,

  I'm looking for a way of "detecting" the pixel-aspect under a given mode.

  My first idea was to first detect the monitor's aspect, and then multiply
that with (mode's height / mode's width). Alas, couldn't find any way to
retrieve that monitor's aspect.

  I need that information to adapt cameras field of views between different
(yet well-known) resolutions like 1280x1024, which is absolutely not a
square pixel on a 4:3 monitor, and 800x600, which is perfectly square. And i
will flame anyone answering difference is not visible ! :)))

  It becomes extremely important now, with some monitors (especially latest
LCDs), allowing to be positioned "vertically" (3:4 monitors), or with weird
resolutions (832x702).

  If anyone could be of a help on that, i would really appreciate !
