LCD flat screen TVs provide a superior picture as compared to a traditional television - and they can come in more attractive styles to boot.
A flat screen LCD TV can be mounted on a wall, under a cabinet, on the ceiling? or can sit on a stand or on top of furniture.
LCD TVs are versatile, flexible, and provide a better entertainment experience? but how do they work?
LCD flat screen TVs, and LCD technology itself, is based on the properties of polarized light.
LCD TVs consist of two, perpendicularly arranged panes of polarized glass "stuck together" by a liquid-crystal-filled polymer solution. When they are exposed to electrical currents, the crystals untwist to varying degrees, permitting specific amounts and colors of light to pass though them.
Flat screen LCD TVs are, in effect, projection TVs that depend on an extremely bright lamp as their light source, so they're considered a "passive" display.
So how do you choose the right flat panel LCD TV for you?
You should at least consider the following factors when shopping for a flat panel LCD TV.
1. Look for a HDMI input.
This port keeps the signal all-digital, avoiding degradation that can occur as the signal passes through other components (like your cable box).
HMDI carries high-definition audio as well as video.
Some satellite receivers and DVD players also connect through this port.
2. Match the LCD TV size to the size of the room where it will be placed.
Because LCD TVs have higher resolutions than conventional TVs, you can sit closer than you normally would, so you can view a larger screen comfortably.
(Keep in mind a 42-inch screen may overwhelm a small room, though.)
3. Decide if you want the picture-in-picture feature.
The picture in picture feature allows you to simultaneously view two video sources at once, with one appearing as a small window on the screen.
If you do want picture-in-picture in your flat panel LCD TV, keep in mind that single-tuner picture-in-picture lets you watch TV in one window and another source (like a DVD) in the second window.
A flat panel LCD TV with two tuners lets you watch two television sources at once.
4. Do you need HDTV?
A flat panel LCD TV with EDTV is cheaper, but it can't display high-definition signals.
The price difference between smaller flat panel HD-ready LCDs and ED-ready LCDs is fairly low, so you're better off buying a HD-ready set.
In fact, most experts say there's little reason to buy a non-HD LCD television. These lower resolution LCD TVs won't be able to accept high-definition signals, so the picture won't look any better than regular analog TV.
And small HD-ready LCD TVs can be found for $500 or less, which is cheap enough that there really isn't much to "save" on a non-HD LCD TV.
5. Check to see if the TV comes with a stand or mounting hardware.
Most flat panel LCD TVs come with a basic table stand, but wall-mounting hardware costs an additional $100 to $200.
6. Look into the manufacturer's warranty policy before buying online.
Some manufacturers have strict policies regarding authorized dealers. If you buy a Sharp LCD Television, for example, from an unauthorized dealer, Sharp may not offer warranty coverage. (However, the retailer may offer a substitute warranty that sufficiently covers you.) The difference in price between an authorized Sharp dealer and a discounter can sometimes be hundreds of dollars, so make sure you're comfortable with the risk of not having a warranty, or make sure you ask the dealer for information about their warranty terms for the flat panel LCD TV you're considering.
7. Finally, learn about LCD TVs. There are far more things to learn about LCD TVs than the above mentioned points. Get educated on how to buy an LCD TV.

Mitsubishi?s Bright New Idea
Mitsubishi?s Bright New Idea
by: John Richardson
Mitsubishi Electric Corporation is well known for their HDTV rear projection sets. Chances are that you have seen those models that utterly dominate large living rooms, and look similar to big square-like boxes that, if hollowed out, could accommodate a family of rottweilers. Those large monsters, in which the picture quality never looked very good from an angle, will soon be relegated to museums, because rear projectors are getting thinner at a fast clip. Now, Mitsubishi is pioneering a new way to approach the rear projection HDTV-they are using Lasers! With this new idea from Mitsubishi, a RPTV (Rear Projection Television) is transformed because a Laser replaces the usual mercury lamp in the rear of the set. The model is still considered a DLP (Digital Light Projection) but the light comes from red, green and blue Lasers! LASER, which stands for light amplification by stimulated emission of radiation...

Objective Meditations: What is Reality?
Objective Meditations: What is Reality?
by: Paul M. Jerard Jr.
Is reality a projection from within the mind, or is it an ?altered lens? into the outside world? Let?s look at the altered lens theory first. Obviously, we are not all looking at the world with the same lens or viewpoint. If that were possible, and we had a consistent moral code of ethics, we would have world peace.
Imagine no wars, conflict, divorce, or crime. It does make you think that John Lennon might have been thousands of years ahead of his time, when he wrote the lyrics for his song, ?Imagine.? Although, we may not agree with every word, the thought of global harmony captivates the mind.
Is this a reality? At this moment in time, it doesn?t look possible. Peace agreements seem so close, and then, an assassination, or a suicide bomb, changes everything. Why is this world not ready for a Mahatma Gandhi, Anwar Sadat, or Martin Luther King, Jr.?
Do we, as a species,...

Bariatric Surgery: Cosmetic or Necessary?
Bariatric Surgery: Cosmetic or Necessary?
by: AllMed Healthcare Management
During the past 20 years, there has been a dramatic increase in obesity in the United States. Thirty states have obesity rates of more than 20 percent. Currently, more than 44 million Americans are considered obese, the result of our fast-food life style and lack of exercise.
As a result, more obese Americans are turning to bariatric surgery. In 1995, just 20,000 weight-loss operations were performed in the United States. Last year, physicians performed 103,000 bariatric surgeries, an increase of more than 500 percent. The projection for 2005 rises to 144,000.
These surgeries are in the range of $30,000 each and if complications arise, even more. Even though some health insurance groups do not include this surgery in their plan language, requests for independent medical reviews regarding bariatric surgery have surged over the past year.
Most of these reviews...

One Of Cancun's Best
One Of Cancun's Best
by: Amy Covington
It's hard to believe that a short 30-mile bus ride from the Spring-break haven of Cancun is one of the top-ranked hotels in Central America and an exotic, unrivaled tropical paradise. While it sounds like typical romance copy, we're not just giving lip service ...the Mayan Riviera is not your standard Mexican vacation destination nor is Maroma Resort a regular lodging establishment, having recently received the Conde Nast Travel Magazine Reader's Choice Award as the #3 hotel in all of Central America. The local culture and natural resources are just some of the attractions that separate Riviera Maya from other popular destinations in Central America. For starters, the second largest barrier reef in the world is located here, providing unsurpassed water activities like snorkeling, wind-surfing, kayaking, sailing, diving, bottom fishing, deep sea and fly fishing. The unspoiled beach offers guests the utmost in privacy...

LCD Projectors - The Jist
LCD Projectors - The Jist
by: Eli Aloisi
An LCD projector is a device utilized for displaying video images or data. They are the modern equivalent to the slide projector and overhead projector used in the past.
LCD (liquid crystal display) projectors usually contain three separate LCD glass panels, one each for the red, green, and blue components of the video signal. As light passes through the LCD panels, individual pixels can be opened to allow light to pass, or closed to block the light, as if each little pixel were fitted with a Venetian blind. This activity modulates the light and produces the image that is projected onto the screen.
With a lens that "projects" the image on any flat surface and does not require large "furniture" (like a big TV would), LCD projectors tend to be smaller and much more portable than older systems. The best image quality can be accomplished with a blank white or grey surface to project on, and for this...
