How is resolution measured on a monitor

Since the 27" iMac is the same physical size as the Thunderbolt Display but has twice the resolution, it has twice the pixel density, measured in pixels per inch, or PPI. NOTE: Unlike monitor resolution, the resolution of a printer or scanner is analogous to pixel density rather than total pixels.

Printer and scanner resolution is measured in dots per inch, or DPI. The definition of Resolution on this page is an original TechTerms.

Most popular are Apple's new retina displays that are on the most recent Macbooks, iPhones, and iPads.

If you're a web developer, check out some ways people are designing for retina or high pixel density displays. Just like web images, images for projectors should match the pixel dimensions of the projector. As with computer monitors, projectors also have their own display dimensions. For example, most aspect projectors have a display of x pixels, so an image that is x pixels with a 72 PPI resolution would be an ideal image size to be displayed from a projector.

For web images, we must focus on the pixel dimensions. Look at the two images below - one is ppi and the other is 72ppi. Pixel Dimensions x ; Resolution ppi. Pixel Dimensions x ; Resolution 72ppi. Both of these images display at the exact same size even though their resolution varies.

This is because the pixel dimensions are what really matter when working with web images. Notice that the pixel dimensions of each image are the same and therefore both images will display at the same size even though they have differing resolutions. University of Michigan Library Research Guides. Resolution is how many pixels the monitor can display at a given time.

The smallest resolution Windows supports is x pixels meaning dots horizontally by vertically. Better video cards and monitors are capable of much higher resolutions.

The standard resolution used today is x
