COMPUTER USE

LCD monitors display static images from computer or VGA sources extremely well, with full color detail, no flicker, and no screen burin-in. Moreover, the number of pixels per square inch on an LCD display is typically higher than other display technologies, so LCD monitors are especially good at displaying large amounts of data-like you would find on an Excel spreadsheet, for example-with exceptional clarity and precision.

Plasma, on the other hand, does not handle static images especially well insofar as "burn-in" is still a major issue with these monitors, as is distortion resulting from lower-resolution panels displaying static images at expanded sizes. Finally, while video images look good on plasmas, there can be some flicker, depending on the quality of the unit and the resolution it’s displaying.

Advantage: LCD, except at "harsh" viewing angles.

CONTRAST

Plasma technology has certainly achieved quite high contrast ratios. Panasonic has even boasted that its plasma displays have a 3000:1 contrast ratio, which is the measure of the blackest black compared to the whitest white. Plasma displays achieve such impressive black levels by using internal algorithms to block the power to particular pixels in order to render a pixel "dark" or black. While this can limit a plasma’s gray scaling, it does produce exceptionally black blacks.

[[image:tv_plasma_lcd.jpg::right:0]] This is a complicated topic: when you’re choosing between plasma and LCD TVs, you’re actually choosing between two competing technologies, both of which achieve similar things (i.e., crystal-clear, color-filled pictures) and come in similar packages (i.e., super-model-thin cases). To complicate the decision-making process further, price is rapidly becoming a non-issue here.
