Project PDA

The resolution of the screen of a PDA refers to the ratio of horizontal by vertical pixels that compose it a higher resolution, larger screen size. According to the classification the screen resolution is different depending on the PDA. Thus, the Palm PDA type, usually have a resolution of 160 x 160 pixels, which can vary depending on the model, the Pocket PC has a resolution of 240 x 340 pixels, and Handheld PC, a minimum of 640 x 240 pixels , Which may in some cases 640 x 480 pixels (VGA resolution).

Display resolution of a digital television or computer display can be an ambiguous term especially as displayed resolution is controlled by different factors in picture-tube (CRT) and flat panel or projection displays using fixed picture-element (pixel) arrays.

One use of the term "Display resolution" applies to fixed-pixel-array displays such as flat-panel plasmas (PDPs), LCDs, front and rear projectors using LCD, DLP or similar technologies and is simply the physical number of columns and rows of pixels creating the display (eg, 852×480; 1366×768 etc). A consequence of having a fixed grid display is that for multiformat video inputs all displays need a "scaling-engine" (a digital video processor that includes a memory array) to match the incoming picture format to the display.

Currently 1024×768 (XGA/XVGA, eXtended), 1280×1024 (SXGA Super eXtended Graphics Array), and 1600×1200 resolution (UXGA, Ultra-eXtended) are the most common display resolutions. Many computer users including CAD users, graphic artists and video game players run their computers at 1600×1200 resolution (UXGA, Ultra-eXtended) or higher if they have the necessary equipment - although 1280×1024 (SXGA Super eXtended Graphics Array) is more widespread as it is the optimum resolution of most 19" monitors. When a computer display resolution is set higher than the physical screen resolution, some systems make the virtual screen scrollable over the physical screen, however, most CRT monitors will accept higher resolutions than their native resolution without scrolling. The true maximum resolution is calculated from the dot pitch. Few CRT manufacturers will quote the true native resolution in their documentation, but most LCD manufacturers do. With digital television and HDTV, vertical resolutions of 720 or 1080 scan lines are typical.

Note: CRT devices do not have a native resolution. They do have scanning limits however and that will affect maximum achieveable resolution.
