Viewing Raster Images On-Screen in Photoshop

Resolution really doesn’t play a role in how you view images on-screen. The display of images on-screen is based on 1 image pixel per 1 screen pixel. The most important issue, then, is making sure that your image fits inside your (or your audience’s) monitor when viewed at 100%. This is where pixel dimensions come into play — especially if you’re putting images on the Web.

When you view an image on-screen, the display size is determined by the pixel dimension, plus the size and setting of the monitor. You therefore need to determine the demographics of your audience and then size your graphics accordingly.

A 17-inch monitor probably displays 1024 by 788 pixels. An 800 x 600 pixel image fills part of the screen. Change the monitor setting to 800 x 600, and the image fills the screen, with each pixel appearing larger.
On a 15-inch monitor, an 800 x 600 pixel image fills the screen. But a 1024 x 768 image can’t be viewed in its entirety.

You may also hear monitor resolution being referred to in graphic display standards, such as VGA (640 x 480 pixels), XGA (1024 x 768 pixels), UXGA (1600 x 1200), and so on.

Resolution is measured in pixels per inch, or ppi. You may also run across the term samples per inch (spi). Another term you will see often is dots per inch (dpi). Dots per inch is always used in reference to printers, scanners, imagesetters, and other paper-outputting devices. You may hear people refer to dpi as printer resolution.
