Conventional picture-tube TVs The familiar sets with CRTs (cathode-ray tubes). Quick take: Still tops for picture quality, these offer wide selection and the best value. Typical sizes: 13 to 40 inches. Price range: Less than $100 to $3,000. Pros: Least expensive type of TV, still the standard for best picture quality. Mature, reliable technology. Cons: Not available in jumbo screen sizes. Big and bulky, larger sets weigh more than 100 pounds.
LCD TVs Like flat-panel computer displays, these thin sets have a backlight and thousands of red, green, and blue pixels that open or close to let light through, creating colorful images. Quick take: Trendy flat screen with decent picture quality, but inch for inch, more expensive than other types of TVs. Typical sizes: 14 to 46 inches. Price range: $500 to $11,000. Pros: Thin and light. Can be wall-mounted. No risk of burn-in of static images. Some can double as a computer display. Cons: Maximum screen size limited--for now at least. Larger models are very costly. Image may dim as you angle away from center of screen, especially up and down. Not as good as picture-tube sets for displaying deep blacks and fast-moving images. Unknown reliability.
Plasma TVs Flat-panel, big-screen TVs with thousands of red, green, and blue pixels that are activated by "plasma"; these work somewhat like fluorescent lights, creating very bright images. Quick take: Big, bright screens with a real wow factor, but expensive. Typical sizes: 32 to 63 inches. Price range: $3,000 to $15,000. Pros: Thin and light enough to be wall-mounted. Big screens with vivid color look impressive. High brightness and contrast. Cons: Power-hungry. Generate lots of heat. Some lack speakers and tuner. Burn-in of static images a concern. Fairly heavy in bigger sizes. Wall-mounting can be costly. Unknown reliability.
Rear-projection (CRT-based) Jumbo sets that beam images onto a screen from three small CRTs inside. Quick take: The lowest-cost big screens, but they're space hogs. Typical sizes: 38 to 61 inches. Price range: $1,000 to $6,000 (for digital models). Pros: Low price, wide selection, plentiful features. Decent reliability. Cons: Picture quality ranks lowest overall among all TV types. Big, bulky, and heavy--more than 200 pounds for largest. CRTs need periodic realignment. Image may dim as you angle away from center of screen. Burn-in of static images a concern.
Rear-projection microdisplays Newer, pricier big-screen sets, most of which use LCD, DLP, or LCoS technology that allow for fairly slim cabinets. Quick take: Relative slimness makes them an attractive big-screen alternative, but still fairly expensive. Typical sizes: 40 to 70 inches. Price range: $2,800 to $7,000. Pros: Thinner and lighter than CRT-based siblings. Cost less than comparably sized plasma sets. No risk of burn-in of static images. Higher resolution and often better picture quality than CRT-based projection units. Cons: Pricey, especially for bigger-screen models. Image on some sets may dim as you angle away from center of screen. Backlight bulb may require periodic replacement. Not as good as picture-tube sets for displaying deep blacks. Some DLP and LCoS models suffer from rainbow effect--flashes of color seen by some viewers. Unknown reliability.
