The fineness of the monitor screen.
|Introduction||The Scale Problem|

Low resolution would be 640 × 480 pixels (width × height). High resolution would be 1280x1024. The Dell 15" WUXGA has 1920x1200. Because the more dots you have, the smaller they are, you must compensate by using a larger monitor for high resolution, or the type will be too small to read.
If you double the resolution, there are four times as many dots. This means the video hardware has four times as much work to do each second to keep the screen refreshed. Further, the computer has four times as many dots to render each time the screen changes. For high resolutions, you thus need high performance video hardware.
Recent LCDs (Liquid Crystal Displaies) use a hardware resolution between 86dpi and 147dpi, only a few LCDs use a resolution around 204dpi (Toshiba, IBM (International Business Machines)).
The problem is ordinary Java apps look too small on these high resolution screens, because Java apps are constructed in pixels, not points or inches the way PostScript is. A program that draws an icon 32 pixels high looks huge on a low res screen, but shrinks down to a mite on an ultra highres screen.
The free and open source JGoodies Forms layout system addresses this issue; it supports non-pixel sizes: pt, mm, cm, in and more important, it supports DLU (Dialog Units) that scale with the resolution and dialog font size. Here is how to find the size and resolution of the screen to use in adjusting your Font and Frame sizes.See a more detailed discussed under scalable layouts.
