Hello,

I noticed that 16:9 aspect ratio is somewhat ~1,777777778 and if I calculate width for the 768 height with that aspect ratio it's something like 1365,33333 (768 * aspect). Rounded that will be 1365. Okey, then final resolution would be 1365x768.

But now I'm wondering why it's so?? The HD-standard and WXGA native resolution is 1366!?! (http://en.wikipedia.org/wiki/WXGA).

If I look my display adapter (nVidia) settings for the resolutions, it would give me to change both of those resolutions (1365 x 768 and 1366 x 76.

For example if I set not scaled 768 pixels height resolution for 16:10 display it would be 768 * aspect ratio (which is ~1,6666666), then width would be ~1279,9 and that's rounded to 1280 which is correct.

Also for example if I set not scaled 768 pixels height resolution for 4:3 display (1,3333 aspect ratio) it would be 768 * 1,3333 =~1023,999 which is rounded to 1024.


So, the question is: which one is the 'correct' width for the 16:9 display on 768 height resolution, 1365 (which is calculated by aspect ratio) or 1366 (which is de-facto standard, but incorrect for ratio)??


Edit: and I'm just phondering this because I liked to choose width which is most supported by display adapters.
