Wide Screen

I had bought 2 screens, both 19-inche.

One is Normal and another is widescreen. I only want to prove that which one has more viewable areas (by Theory).

Normal screen has ratio of wide and height at 4:3 and wide screen 16:9; So if we want to compare easier then change 4:3 to 16:12.

So the diagonal line can be calculated as



a2 + b2 = c2

While a = width; b=height and c=diagonal;

thus that:

Normal one will have a coefficient as “A” and wide one will define as “B”

then




Normal: (12A)2 + (16A)2 = 192




Wide: (9B)2 + (16B)2 = 192


and then

A2 = 361/400 and B2 = 361/337




A = 19/20 and B = 19/18.358







Area = a x b



Then




normal: (12 x 19/20) x (16 x 19/20) = 173.28 in2

and




wide: (9 x 19/18.358) x (16 x 19/18.358) = 154.25 in2


So wide screen has less space than normal one. * *
