# To find the pixels per square inch of each monitor

Essay by EssaySwap ContributorUniversity, Master's February 2008

To find the pixels per square inch of each monitor I had to do a few things. First, I looked in each computers' control panel to see what each monitors maximum resolution was. Then, with a ruler, I measured each computer monitor. Then, I multiplied the maximum resolution numbers together and then divided it by the size of the monitor. This number gave me the pixels per square inch for each screen.

I measured five different computer screens. The first one was a MacintoshiMac. Its resolution was (800)(600) and it's monitor length was (9)(11.5). I multiplied the numbers then divided and the pixels per square in.was 4,637.68.

The second monitor was a Macintosh laptop Powerbook. Its resolution was (640)(480) and its length was (8.5)(6.3). This gave me 5, 736.68 pixels per square in.

The third monitor was a Power Macintosh. (640)(480) and (10.5)(8). All together it had 3,657.14

pixels per square in.

The fourth monitor was a AOC Spectrum 5E. (800)(600) and (11)(8.5). The pixels per square inch was 5, 133.69.

The last monitor was a Gateway 2000. It had a resolution of (640)(480) and size was (11)(11). The pixels per square in. was 2,487.45.

The more pixels per square inch the better the resolution the monitor will have.

The laptops monitor was the smallest so it had the most pixels per square inch. The laptop would have the best resolution. Followed by the AOC Spectrum, then MacintoshiMac, Power Macintosh, and the Gateway last.

The approximate price for the laptop was \$309. The other macintosh monitor prices were unavailable. The Spectrum monitor costs about \$330 dollars, and the Gateway monitor costs about \$160.
