What's the difference between HDTV, LCDTV,Plasma TV, and 1080P TV?

Q. Which one has better reception, dependable and cost-saver?
Which stores carry those?
Your sincerest answers, advices and suggestions are highly appreciated. Thank you very much.

A. Almost all LCD and Plasma sets sold today are HDTV's. You should see the HDTV logo on the set somewhere. If the set is an HDTV that means it is capable of high resolution display. The display across the screen is measured in tiny units of light called pixels and they are measured in width x height. The combination of these pixels make up the image you see. Standard Definition television (what we've all grown up on and have had for the last 40+ years) is approximately 520x480 at it's absolute best. Modern High Definition displays (HDTV's) offer 1920x1080. An LCD or Plasma set that can display 1920x1080 is said to be a 1080p capable HDTV. On some older models and budget-minded models the HDTV may only offer 1280x720 resolution. This is called 720p.

Do you need 1080p? That answer depends on screen size to viewing distance. If you're going to purchase a 42" LCD display and sit 12 feet back, a person with 20/20 vision will not be able to see the benefit of 1080p over 720p. However, if you invest in a larger display (say 55") and you set 6 feet back, you would be able to see the benefit of 1080p. With modern HDTV's although the 1080p resolution may or may not be important to you, often other important features will only be available on 1080p models (e.g. Samsung's middle-of-the-road 650 series LCD's are all 1080p)

You will see some displays advertised as 120hz or even 250hz, etc... If you intend to buy a Blu-Ray player down the road, 120hz is a good idea because it allows for film material to be displayed in it's native refresh rate (24fps) it also enabled motion enhancement features, again these are features you look for that you'll have to pay for. You won't find these features on a bargain hunters LCD HDTV.

To answer the question about Plasma vs LCD. On the outside (when powered off) you would not likely be able to tell the difference, the technology on the inside is however very different. LCD's use crystals that when current is passed over produces an image. Plasma's use charged phosphor gas to create an image. Generally LCD's consume less power, however Plasma is considered to have better performance (much less 'judder' which is jerkiness caused on some film material) and overall better picture quality. Each technology has it's pro's and con's, but LCD has won the battle (as is apparent with more and more Plasma sets being discontinued each year). LCD has a longer life than Plasma because it does it burn phosphor. Price on LCD and Plasma varies by brand name and series. Any given manufacture will offer many different models, Samsung and SONY are considered by many to be the best choice for LCD displays. Samsung for example has many series ranging from 350 to 950 with price with the 950 series being their most premium offering. You get what you pay for, but most people will probably be happy with a middle of the line produce (650 series Samsung or comparable model by other vendor) as the extreme high-end features will cost a lot and will not likely matter to the average joe. However do buy a brand name product! There are many LCD and Plasma displays on the market that are prone to high defect rate and the warranty on non-name brand is often bad (these sets can not be easily repaired as the old tube based televisions can).


Where is the best place to buy good quality a television for a good price?
Q. Preferably a 40-49 inch, between the price range of $450-$600...

A. I would recommend you to buy it online as if you get from local stores you pay sales tax which can be $55 or more for $600 you spend.

many stores online have $0 shipping and $0 sales tax.
