Comment 36 for bug 188792

> I’ve never seen a CRT which has a 5:4 aspect ratio.

There were several on the market back when 1280x1024 was a top-notch resolution.

At that time, only the Mac-specific monitors in that pixel-class were
designed for 1280x960. Everyone else went for a 5x4 1280x1024.

(I once drove one such monitor at 1168x930 — 1160x928 with a few extra
pixels horizontally because the card required a width divisible by 16
and a couple of extra lines just because I could — to get a better-than-
60 Hz refresh rate.)
