Which HDTV should we buy? An LCD, a Plasma, or an LED-LCD?

Q. We are looking to spend no more than 1500 dollars and the tv MUST be 42". The room it will be in is usually well lit. Let me know if you have personal experience or any suggestions. Thanks in advance!!!

A. I've done some research on LCD vs Plasma vs DLP and here are my results:

Plasma:
Generally better home-theater image quality than LCD; wide viewing angles; superior motion resolution (which means you do not see blurs in fast-action movies/tv shows/etc.).
Bulkier and less energy-efficient than LCDs; sometimes lower native resolution than similarly sized LCDs; glass screens can reflect ambient light.
The best plasmas produce top-notch image quality, with deep black levels, excellent color, wide viewing angles, and better motion resolution than similar LCDs, making them subject to less blurring during fast movement.
Most plasma makers today claim a life span of 60,000 hours before the panel fades to half brightness. That's more than 20 years if the TV is on for 8 hours per day.
Things to watch out for: Burn in, Glare, get a model with with good black-level performance (Contrast ratios),

LCD:
One definite advantage of LCD TVs, is that their matte plastic screens reflect less ambient light than plasmas' glass, so they're usually better for very bright rooms with little light control. Note that some LCDs have glossy screens, as opposed to matte (glossy = not so good in light rooms).
Sleeker, weighs less, and more energy efficient than Plasma (but sleeker is a relative term since plasmas are slim)
PC Connections are more common on LCDs than Plasma
Same life expectancy as Plasma


DLP:
Less-expensive at very large screen sizes than plasma; good black-level performance on the best models.
Lamp requires periodic replacement; thicker and bulkier than flat-panels; less-impressive off-angle performance than plasma.
Can produce soft edges on picture quality (not good)
Easy to replace light bulb (which lasts only 3000 hrs)
Picture Quality does not fade over time as Plasma and LCD

Winner: That depends on how it is used. For me, Plasma dominates the rest because the TV is mainly used to watch movies in a dark room.


What type of HDTV has the BEST graphics: LED, LCD or Plasma TV?
Q. [:

A. plasma screen presents deep blacks and good picture. however lcd tvs are more immune to glare.led is the best overall. they have the best quality picture of the three. plus they use much less energy. most led tvs come in 1080p resolution, which also results in stunning graphics. there are little lines that go horrizontally across tv sceens to produce picture. some tvs have 720p resolution. so they have 720 lines that go across the screen to produce picture. 1080p has 1,080 lines that go across the screen, which results in more detail. so another reason why LED tvs are the best is b/c most of them come in 1080p. some plasmas and lcd tv's also come in 1080p. another thing to know is refresh rate. refesh rate is how many times the screen changes in one second. most tvs are available in 60Hz, 120Hz, 240Hz. (Hz=herts A.K.A refresh rate.) so a 120 Hz screen will change 120 times each second. but a 240Hz screen will change 240 times each second. so the screen picture will result in a more fluid picture. the main purpose of refresh rate is to reduce bluryness. this comes in handy in fast moving picture, which can cause a lot of bluryness. most plasmas and lcd tvs are only available in 120Hz. most LED tvs are available in 120HZ and 240HZ. again with Led graphics being better. so without a doubt, LED is a better tv that can produce more detailed, smoother graphics. hope i helped. deuces :)
