16:9 Math Issues
Wow ... lots of trigonometrically challenged posts here! actual screen dimensions for 16:9 aspect ratio screens are:<br />5&quot; diag --&gt; 4.36&quot; x 2.45&quot; = 10.68 sq.in.<br />7&quot; diag --&gt; 6.10&quot; x  3.43&quot; = 20.93 sq.in.<br />So ... the 7&quot; screen has approx 2x the  viewing area of the 5&quot;.
