ppi calculator, what resolution should you get?

[Vazine]

Hey guys,
I figured there are a lot of people shopping for laptops and whatnot around this forum. I calculate the ppi (pixels per inch) of monitors before I buy the laptop(or screen) since my eyesight isn't the best.

Here's a link to my program which I wrote in C++ and compiled to run on a windows platform. It's very simple, just uses some simple trig to calculate the ppi based on the screen size and resolution.

Then click on the link "My C++ Programs"

Here's a sample run of the program (ppi.exe):



Welcome to the ppi calculator



Enter the size of monitor 1 in inches: 15

Enter the horizontal component of the resolution: 1400

Enter the vertical component of the resolution: 1050

A 15 inch monitor with a resolution of 1400x1050
has a pixel per inch ratio of : 116

Are you done (y/n)? n

Enter the size of monitor 2 in inches: 14.1

Enter the horizontal component of the resolution: 1024

Enter the vertical component of the resolution: 768

A 14.1 inch monitor with a resolution of 1024x768
has a pixel per inch ratio of : 90


Percent difference between monitor 1 and monitor 2 : 23%


Are you done (y/n)? y


So if you enter the specs of more than one monitor it will give a percent difference between it and the first monitor entered.

Let me know what you guys think!!

Without my glasses I'm comfortable with up to 85 pixels per inch, but with my glasses I'm comfortable with up to 110 pixels per inch.


Oh yea, my geocities site is free so it only allows 4.6 MB/hour upload. So if you can't get it now try again in an hour or so.
