Regarding the 4:3 aspect thing... Your monitor uses square pixels regardless of what resolution it's set at. The aspect ratios that you are referring to are relevant in the video realm where TV screens and some of the media use non-4:3 pixels. It doesn't apply to your monitor unless you're trying to display something specifically set to be non-4:3 on your monitor. Well, square as differing from what, round? ;-) Let me make a simple example- you have a display that measures physically 12" wide x 9" high (thus 4:3 ratio). Your ultra-cheap display card uses a 640 x 350 (the old EGA ratio, a not-square one). The pixels actually measure .01875" wide x .0257 high. Non square, right? Now, to show what happens when you rotate a circle with is display, you draw one on the screen that seems perfectly round, it is 257 pixels wide X 188 pixels high, and measures 4.82" wide and high. Now, you rotate it 90 degress in PhotoShop. Photoshop rotates the actual pixels, so the former circle is now 188 pixels wide x 257 pixels high. The oval on the screen measures 3.52" wide x 6.60: high. Oh My! Bear in mind most modes aren't as non-square as the old EGA ratio, ut uou get the idea how it goes. ;-)
