Plasma, LCD, projector, CRT? The choice of display technologies can be overwhelming for the un- or under-informed. Which TV should you next choose?
CHOOSING LCD
Slim and desirable, LCD screens are the new belles of the TV Ball. But they're not as perfect as you think...
Liquid Crystal Displays have been around for over 20 years, but have only recently become a reality in the TV market.
The reason for this is that their fundamental operation relies on crystals moving in a viscous liquid and, like wading in treacle, it's a very slow process. Early generation LCD panels simply could not switch pixels on and off fast enough to cope with a moving video image, and consequently remained in clock displays and PC monitors that were predominantly used for near-static images.
Thankfully, as the technology has developed, the pixel-switching time has dropped dramatically and, in the very best models, causes very little motion blur on moving images. This has opened the floodgates for LCD TVs right up to over 50 inches. However, unlike plasmas, price is no indication of quality.
Hot or Not?
LCD contrast ratio is generally poorer than any other TV technology as the backlight can leak through the "switched off" pixels. A potent backlight can lift the brightness figures, but colour is dependent on single block filtering, so the total range of colours and the colour saturation are also mediocre. The deep liquid crystal substrate means the picture integrity fades away as you move off axis, although the latest models claim a viewing angle up to 170 degrees. That said, manufacturer's specification sheets can read like Tolkien-scale fiction at times, so getting a demonstration of an LCD TV before you buy is essential.
So why is LCD currently the must-have technology? Not only are LCD TVs a super slim flat panel, they are much lighter in weight than plasma models, as the LCD itself is made from plastic rather than glass. Screen resolutions are HD-friendly on larger screen models and each pixel has a much better defined edge definition than the glowing phosphor dots of plasma or CRT - creating a very sharp image. LCD TVs do not suffer screen burn-in from constantly displaying static images, are silent in operation and, from an energy-saving perspective, use little electricity.
But the biggest key to LCD TV's rise has been falling prices. Each panel is cut out of a single large sheet of fully engineered LCD and each new manufacturing generation creates larger initial sheets. This reduces cost per unit and hence the street price.
LCD TV costs will continue to fall, the picture quality will continue to rise and, as features like digital tuners, memory card readers and wireless connectivity become mainstream, LCD TVs will dominate the 32 inch flat panel market.
As long as you make sure you are buying an HD-ready model and try before you buy, you can't go wrong.

Why Should I Choose A 7.1 Home Theater System?
Getting a quality 7.1 theater system in your home can be great as you enjoy at home the movie experience of sound in your dvds. But making sure you get the system installed correctly is key as you will want to not waste your money on a system that does not work properly.
As you consider your home theater investment consider what you want exactly. If you don't know do some research enough so you know what you are talking about. You can't major in technology overnight but you will want to have enough information to know what you are talking about.
So what I found out is that the 7.1 part of the term means the quality and power of the speakers. Home theater system is a term but the 7.1 part of it tells you the power of it. And that part is specific to people who know what the heck that means.
What I also found out is the power of the speaker is important for especially THX sound. The power of the speaker is so you can have movie sound quality and not blow out the speaker. This makes sense to me because the space is so much smaller than a giant movie theater.
So with this limited knowledge I can kind of understand why the person is explaining to me why the 7.1 speakers are better than the 5.1 speakers. But I still don't feel confident to know what I am doing.
What I do know is that I don't have enough knowledge to do anything without an expert. I feel like I can get a quality system and write the check okay but I also realize with strong conviction that I need an expert in my corner to help me get my system to what I want. I need a consultant that can supervise the installation and make sure that everything is set up properly to code and the sound doesn't flood into any of the other rooms.
The consultant usually has connections and can hook you up with a great price on a 7.1 home theater system as well. Through their wholesale affiliates you can get the most for your money and get the killer theater room you always dreamed of.
Purchasing a quality 7.1 Home Theater system can bring a lot of fun. Discover special offers at http://www.71hometheaters.com.
