**2/20/09**Added a calculator:

LCD Calculator v2.txt 2k .txt file

Just download and change the file format from

**.txt**to

**.vbs**. It should work in any recent Windows OS. I have added maximum view distances before the eye starts losing detail. I also included the view distance for 30 degree angle which is the recommend angle for immersion.

**Viewing Distance Calculator**

This is more for HDTV but may be useful for some: http://www.myhometheater.homestead.c...alculator.html

Here's a chart for optimal viewing distances: http://hdguru.com/wp-content/uploads...ance_chart.pdf

My Spreadsheet:

**Monitor Size:**the distance in inches from one corner to the other of your viewable area

**Aspect Ratio:**width and height proportions

**Resolution:**number of horizontal and vertical pixels

**Pixels:**number of discreet pixels

**Width:**estimated width of viewable area

**Heigth:**estimated height of viewable area

**Area:**estimate area of viewable area. Use this to compare the difference in size of two monitors. A 19" normal monitor actually is bigger than a 19" widescreen.

**Pixels Per Inch:**Pixels density. This is how "sharp" the image is and is related to pixel pitch. From the chart, you can see that a 22" widescreen has a better image than a normal 19". The 24" is even better and then look at the 30" density!

NOTE: Minimum Viewing Distance is not correct. Forget to divide by pi for a multipler, doh!

Equation to find height and length

Pythagorean Theorem: a^2 + b^2 = c^2

a = x * height

b = x * width

(h*x)^2 + (w*x)^2 = c^2

h^2*x^2 + w^2*x^2 = c^2

x^2*(h^2 + w^2)= c^2

x = (c^2/(h^2+w^2))^.5
