shopping 4 a big screen TV (42-46''). Need advice on DLP, PLASMA, and LCD.?

Question

please include information on picture burn-ins, lamp burn-outs, depths, average lifetime, and best for the price. May be make/model also, and if additional warranties are needed.

Answer 1

Plasma, works with noble gases as in neon lights, these take up the most energy, create lots of heat, risk of burn-in if left on a still picture or text, dont last a very long time, and cost lots of money. The picture looks very vibrant and colorful.

LCD, works with liquid inside the screen and LEDs, it has a slower response time than any other type of TV, sometimes the LEDs can go out and you get dead pixels, which can be annoying, the picture quality is good, price is decent, they take up the 2nd least amount of energy, and they last an okay amount of time.

DLP, of course works with light projectors, they are hard to see at certain angles and are very big. You risk getting a burn-in. These TVs dont last too long, maybe 2-8years, there is coolant leaks, and lamps that go out. The prices on these are very fair.
--DO NOT BUY RCA of this type of TV, there are many many many complaints and problems with these

CRT, works with 3electron guns(RGB) that shoot beams of electricity on phosphors that light up on the screen. These are my favorite type of TV, they are very cheap, last a long time, and rarely have problems, the only thing with these are, they generate a decent amount of heat, they are big, hard to find over 40in", and they take up the second most amount of energy--make sure to buy with a very low number Dot pitch and buy a flat screen.

SED, work like CRTs but have many many tiny electron guns. These take up the least amount of energy, last the longest, the picture quility is Great, they are the same size as LCDs, BUT they are Very expensive!

Good luck with your new TV!

When considering HDTVs you need to consider your situation to make the best decision about the purchase: where are you going to sit, what are you going to watch, whats the lighting situation, where do you want to put the TV. If you're sitting at extreme angles throw out the projections, if light will glare off the screen plasma isn't a great idea because its a sheet of glass and the reflects, if you're going to mount the TV throw out DLP, etc etc. The lamp in a DLP will need to be replaced roughly every three years (about 3k hours), most major retailers service policies cover the replacement of the bulb. You can expect around 60k hours out of both plasma and lcd. I'd seriously consider purchasing extended service on HDTVs, they're a big investment. DLP is the best for the money but has its downsides. The best way to pick a tv is to look at them and buy which picture you like the best. Keep in mind, a plasma consumes a lot of power and these TVs should have a clean consistent flow of power, look into a Panamax Power conditioner (MX4300 w/o audio, MX5100/5300 w/ audio) and a good set of cords is a plus. Don't forget YOU NEED AN HD SOURCE, if you're on Direct/Dish get better cables...you have a better signal.

Plasma vs LCD:

Picture quality of plasma is brighter, better color, better blacks than LCD. (There is something about looking directly at glowing phosphors!)

Sharpness is the same for equivalent pixel counts. Some newer LCDs have 1080 x 1920 resolution, most plasmas still in the 720 x 1280 range.

Plasma is heavier and uses more power than flat panel LCD.

There are reports that plasmas are not as reliable or they don't last as long, but that is no longer true with the latest models. Plasma phosphors dim slowly over time (but not as fast as CRT phosphors); but direct view LCDs use flourescent lamps which also dim and eventually burn out (some are replaceable). Projection LCD sets have bulbs of limited life, but are replaceable and the lifetime is a few thousand hours of viewing.

Plasmas are subject to burn-in. A stationary image left on the screen for a long time could produce a permanent ghost image. The most risk is when viewing a lot of 4:3 ratio pictures (non-HD), which are displayed with vertical dark areas on the left and right to fill in the wide screen. There are ways to minimize this, however. many sets have a "stretch" mode which widens the picture to fill the whole screen. This could also be a problem with extended playing of video games if there is a background image that remains stationary.

Plasmas come in largers sizes, although large flat panel LCDs are coming out, but they are expensive. LCD projectors can be 70".

LCD contrast and brightness can be reduced when viewing from off-center (both flat and projector, but sets will vary).

DLP vs LCD:


LCD (liquid crystal display) is available either as flat panel, rear projection or front projection TV; DLP is available as projection TV only. To learn the techincal difference, see

http://en.wikipedia.org/wiki/lcd_display...
http://en.wikipedia.org/wiki/dlp...

At present, DLP provides higher brightness and more contrast than most LCD. An exception is the Sony SXRD, which can match DLP contrast and black levels. You have to be wary of the "rainbow effect" in DLP displays: before buying a DLP TV, look at a picture with bright areas and scan your eyes across the screen. If you see a trail of colors, you can see the "rainbow" and you may want to avoid this set. Many people (including me) cannot see these, but some can. For all sets, check off-center viewing of the screen. LCD flat panel in particular can lose brightness and contrast in off-center viewing. Both LCD projectors and DLP projectors are available in "1080p" resolution (they display 1920x1080 pixels on the screen). However, only the Sony SXRD is true 1080p; the DLP sets simulate this resolution with a tecnique called "wobulation". See

http://en.wikipedia.org/wiki/wobulation...

These DLP sets do provide a high resolution picture that is a little "softer" than the LCD units, but some people find that preferable (more "film like").

You should go look at the set and decide what you like better.
