Well everybody used 1280x1024, but I'm not too sure that the monitors were
really 5:4. I've got a 19" CRT here for instance which clearly is 4:3, and
there were lots of similar monitors around that time. And especially the
cheaper ones, while they could run 1600x1200, it was unusable due to fuzziness
and restriction to 60Hz, so everybody just used 1280x1024 on them. But you may
be right some might indeed have been 5:4. Anyway, even if the monitor in
question here really is 5:4 physically, there's nothing in the edid data which
would indicate this - in fact edid just shows it's 4:3. So there's absolutely
nothing the driver could do to figure out it should indeed chose a 5:4
resolution by default.
