14 This isn't actually a Gentoo or even a hardware issue, what you describe is
15 exactly what should be expected. The issue is that most CRT, and many LCD
16 monitors are designed to display a "4 by 3" aspect ratio, the actual pixel
17 elements that make up the phyiscal surface of the display are actually this
18 size . 1280x960 IS 4:3 (1280/4 = 960/3) 1280x1024 is NOT 4:3 (1280/4 !=
19 1024/3). If you created something that generated circles in an environment
20 that was NOT 4:3, you can't expect it to also generate circles in an
21 environment that IS 4:3, and vice versa.
