Computer monitors are available using a number of different types of technology. Liquid crystal display (LCD) monitors are the most popular model currently in use in the United States, at least on new machines. These monitors are typically thin and light. The cathode ray tube (CRT) is the second most popular version. CRT monitors are bulky and heavy, almost like an older television (albeit a small one). Some of the less common technologies used are plasma monitors, surface conduction electron admitter monitors, organic light emitting diodes, and video projector displays.
The resolution of a monitor, a number measured in pixels, is important to its quality and functionality. CRT monitors are very versatile, usually capable of displaying a resolution ranging from 320 x 200 all the way up to a 2048 x 1536. The highest resolution in use as of the publication of this article is 3840 x 2400 pixel display, used only on an LCD monitor.
Many people have wondered over time what a screen saver was really for. Well, we can tell you. Especially on CRT monitors, if an image is displayed for a very long time, there is a chance it could imbed itself into the glass of the monitor. This phenomenon always leaves a faint trace, making it look like that image is still on the screen, when in fact it isn’t. Screen savers, software programs which cause the image on a screen to change quite frequently, keep this from taking place. They save your screen.
