Since what you actually care about is visible area, I'd just get out a ruler and measure. Crude, low tech, inelegant, but quite effective!

| Post subject: | YARD - Yet another Aspect Ratio Dimensionizer |
I'm embarassed at how much trouble I have with this simple math: If I see a spec sheet for a 17" monitor and I know that it is a 16: +/- 9 aspect ratio (1280 x 768 -- a little bit different than "16:9"...), how can I figure out the W & H? Pythagoras has got me as far as figuring out the square of the hypotenuse, but determining the two sides using ratios was impossible! So, I became a high school student again and went online to learn about sines, cosines and tangents. Boy, the things I didn't learn when I was the right age! So, since I didn't want to have to do that much figuring again (*that* hasn't changed since I was 17...), I wrote a quick Javascript to help me figure out how wide and how tall any diagonal dimension on a monitor works out to be -- important, as I consider whether a 17" 1280x768 is too small (it is, the great New Egg price notwithstanding). It's ugly, but functional. If anyone else is wanting to get the same answers that I was, this is my gift to you. If my math is way off, some kind soul should let me know. http://www.directedmotion.com/monitors/yarc.htm |

well 1024x768 is the standard 4x3 aspect ratio. |
