LCD

Liquid Crystal Display. Laptops use a flat panel screen that works much like the display on a digital watch. The problems with LCD are washout if there is high ambient light, and viewing angle. Sometimes you have to look at the screen from just the right angle to see the display. Technology is gradually solving these problems, but it still has a way to go to match the brightness of the old CRT technology or the expensive gas plasma technology. It won’t be too much longer till you can panel your desk with LCDs to form a giant wrap-around screen or wear a headset that gives the same effect. High end users get the effect with three monitors on their desk and a video card to make them behave like on giant screen. Other than much lower power consumption, the other big advantage of LCDs over CRTs is lack of flicker. This lets you read much faster. Flicker distracts the eye and causes it to unconsciously dart about looking for predators.

Connections

LCD monitors come in old analog and new digital style. Some support both with two connectors, a VGA and a DVI-D or rarely with an integrated DVI-I connector. Analog is supported with the old VGA connector or an integrated DVI-I connector. Digital monitors are supported with a digital-only DVI-D connector or an integrated DVI-I connector. Make sure your computer and monitor match.
