Despite the slowdown of world economic, more and more HDTV model being announced, with all new features of advanced technologies whether it be 3d tv or led tv, encourage you to buy a new hdtv without delay.
However, buying an HDTV is a long term investment, there are several important things you need to think about before invest your money on any new hdtv model:
1. What HDTV size suitable for you?
You may need to check your room size and its available space including your viewing distance. Since HDTV's resolution is far greater than SDTV therefore you can sit anywhere closer than SDTV which is from 1.5 to 3 times the screen size in inches. For example, if your viewing distance 4 metres which is around 157.5 inches, therefore the maximum size of your tv would be 105 inch and minimum size would be 52 inch.
2. TV color and style
Well, this is seem to be only small point but somehow it's also important, the same 32 inch led hd tv will surely have little different style for different brand, so it's best to select the style and color to matches your room's color and existing furnitures.
3. What HDTV features do you really need?
Do you need 720p or 1080p, which 1080p will provide higher viewing resolution? If you are the fan of sport tv you may have to look for a 120Hz or 200Hz LCD which will give a smooth motion for faster action, while you may need to consider waterproof feature if you need that tv for your kitchen or bathroom.
4. Brand
Which brand is best for you - may need to think about which feature do you need such as being able to connect the internet, play the game, etc. You can also go to any tv review website or forum to see what others are saying about any specific brand/model.
5. Price
This is the most important for your buying decision. If you are shopping on a limited budget, consider smaller screen may save your money. Be sure to check and compare tv prices online, most tv retailers offer cheaper price online. One more thing not to forget is to check the shipping price. Some online shop may offer you cheaper price for television but they get more money from shipping rate. So make sure to add tv price and shipping rate together plus tax rate (if their prices excluding vat) when compare.
6. Where to buy?
The good start is to check the shop who currently offer best price online whether they have good reputation, how reliable they are? You should also check their return policy and how they ship the product?

LED Backlight
2. Base on standard white LED backlighting. This light is evenly distributed in the plane parallel matrix LCD screen lets you adjust the backlight intensity in different ways in different parts of the screen when needed. One interesting feature that many of us.
Most monitors have a home onboard white LED backlight. Thus, the public display of the home usually have an advantage because of a white LED backlight. Other types of LED lighting can be popular in the future, but that's what we have now. Sales representative might be the promise of a LED backlight will affect almost all functions and features of the screen. Really now?
This is usually a person who now has a LCD screen and is very happy with the product, there are now more likely to be very reluctant to change the display of them, and we have to first see some reliable data and information only. Obviously, you do not miss understand my intention here. Experience the LCD is also very surprising. However, now is really new and may have some improvements or adjustments LED display knowledge the LED to ensure that light cannot escape and cannot affect the sound quality of the image next to them. The audit of WFP's technology, fluorescent lighting that allows light to escape and dark place to sharpness of the images may not respect the potential purity and brightness of your monitor is larger than normal.
A LED display with a vision of light to further enhance the image quality of images on backlit LCD display, the local light in the foreground of the screen, and loss. It is better that the LED displays have solved the problem using the machine, and this is generally excellent across the screen, not the least clock LED prototype that's true, ergonomics, and demonstrated that only dimensional. In fact, only thinner and lighter than standard LCD and can give you the opportunity to maintain their position for the pleasure of them and can treat large areas. Strengths and weaknesses can be seen that LED bulb are available now, and you have the means to choose the kind of impression you want to be able to choose for the movie of the game and the satisfaction and happiness.
In other words, although the first models were not too expensive, you would not need one in your room anyway. Not yet, anyway. However television in 3-D glasses that requires increased with the addition of passive glasses. Active glass are heavy, expensive batteries are required and need to be in constant communication with an IR emitter on the top of the TV to stay in sync. They were the standard for TV buyers so far. Passive glass are the same type you use on a movie theater when you go, see a movie like Avatar, and now they come with television. They are light, cheap (you can only get out of a theater with a couple), does not need batteries, and because they do not need to communicate with the TV at all, they are universal . Passive glasses work with TV from a friend.
At the technical level, working actively flipping glasses open and close the LCD glass thousands of times per minute to be sure of the right eye receives the images for the right eye and vice versa. Passive glasses work with polarized lenses that match the polarization of the images shown on television. In addition to making them much cheaper and easier, so this design minimizes crosstalk. Crosstalk occurs when images are limited to one eye seems unintentionally to both eyes, making a Flickery, the ghostly image. This symptom usually occurs from the fundamental inaccuracy of trying hard to get a pair of glasses and a TV to perform a dance coordinated split-second maneuvers 60 times per second. It is not always going to be perfect. Since passive glasses are not subjecting to the same thin margins Razer gaffe, they help to reduce crosstalk.
For the first time that you look at the track will be amazed with the depth of LED video and graphics appear in any of them, offering an unforgettable experience for the first time. These monitors have automatic brightness, which means that the device can automatically increase or decrease the brightness of the screen suggested the current settings. These monitors have the LED backlight amazing technique that is anything to go by. You have the desire to improve the sound effects when you're watching a movie or play? In fact I like it a lot more with the 5.1 surround home theater system, but if you prefer, you can purchase a sound system installed screen. Anyway, it's really up to you, but one thing is certain, you will be surprised with strong, clear images on the monitor LED, may occur. Do you have an idea of motion blur? Obviously, if the LED is likely to forget what this phrase means for the simple reason that his image is so strong that they do not see any kind of fuzzy with them. In line with the LED and LCD technology is exactly the same when it comes to control, the LED will only inch thick and do not use the earth's surface on your computer desktop. LED monitor has a stable base for an efficient use of energy could not do better. No tracking efficiency in the market with these characteristics.
Again, all these remarkable features and unbeatable include also some disadvantages. Its main drawback is the lack of ergonomic capabilities, then you should consider before buying. Another flaw of these monitors can be attributed to the unflattering light on the screen that can irritate the eyes on the consumer long. Those drugs have disabilities must be careful to use any of these. As LED displays have low light, which runs the risk of not enjoy the game effects. Monitors who currently run the cost of almost 50% more than the LCD the same size, but there are important benefits in addition to negative from scratch with the latest modern other cost increases.
