Mastering Physics Solutions: Resolving Pixels on a Computer Screen

On May 6, 2013, in Chapter 24: Physical Optics: The Wave Nature of Light, by Mastering Physics Solutions

Part A = d = 3.10 mm
Part B = d = 1660 m

A standard 14.16-inch (0.360-meter) computer monitor is 1024 pixels wide and 768 pixels tall. Each pixel is a square approximately 281 micrometers on each side. Up close, you can see the individual pixels, but from a distance they appear to blend together and form the image on the screen.
If the maximum distance between the screen and your eyes at which you can just barely resolve two adjacent pixels is 1.30 meters, what is the effective diameter d of your pupil?
Assuming the screen looks sufficiently bright, at what distance can you no longer resolve two pixels on diagonally opposite corners of the screen, so that the entire screen looks like a single spot?
