How to choose an HDTV
As the technology changes from analog to digital transmission of the number of options the selection of a new generation of Digital Television is growing dramatically. It's just a question to the local television market and the selection TV go for the best. For the first time, there are many other factors to understand and evaluate.
Native Resolution
First, we briefly resolution screen. Digital definition.High not necessarily mean high definition TV, or HDTV, covers all television sets will be displayed at a resolution screen 720, the 720 horizontal lines of pixels. Pixel is a colored dot on the screen. Native resolution is the highest resolution, pixels, or television can display. Native resolution of 1280 × 720 means that the device is in a position to 1280 pixels on 720 lines of horizontal line points vertical to reproduce. The highest resolution currently available is 1080p (1920 x 1080) and 1080i (1920 × 1080). In general, the higher the resolution, consider that the best image.
Small HDTV 45-inch screens (measured diagonally), may not be able to tell the difference between 720p and 1080p picture I say, that may be useful to pay more for a higher resolution. How many articles can be on screen with higher resolution before the advantage is lost packaging. Personally, I think, in 1080 slightly smaller 45-inch screen, especially if it would be very difficult to see the difference. If you are looking for a Big Screen and save your money for a 720p display.
Progressive versus interlaced displays
"P" and the designation of 'i' sometimes confuse people. 'P' the liberal media, which means that each line displayed on the screen in the correct order (line 1, line 2 line 3, etc) means. "I" means interlaced, which means that the odd lines are displayed by means of a single layer and in line pairs next round. Use interlaced analog TV technology. Progressive views are not necessarily better. Most people can not tell the difference between 1080i and 1080p image resolution, because they are the same. 1080 advantage comes into play with a quick movement on the screen that appears smoother and less distortion. If you have a lot of action movies, or football and watch a big screen HDTV, 1080p may be your best option.
The size of the screen must be removed
Usually, a big mistake, the biggest screen you can buy. emissions standard definition television almost all look at a HDTV, if you're terribly close enough, but how do you want to improve Volver A good field of view, the images are dramatic. The fact is that in the translation of 480 pixels on a single standard television 720 pixels or 1080 pixels occurs at a certain degree of distortion as a TV question to correct the colors for each pixel, calculate the missing. If you place a large screen HDTV in a small room, probably will be disappointed in the quality, if you are still seeing high-definition video and Blu-ray movies or HD cable or satellite.
There are many good online maps for information on the calculation of the ideal distance for the screen HDTV. The basic rule is that you should not be closer 1.5 times the diagonal of the screen. The maximum distance for the best picture quality is about 3 times diagonally.To calculate this by hand to start with a screen size measured diagonally. If you look at the TV screen of 40 inches, the minimum distance is 60 inches (40 x 1.5 = 60 inches or 5 feet) and 120 cm (40 x 3 = 120 cm or 10 feet) should be.
Whenever you are looking for HDTV, make sure you know where to sit to the distance between people, which will host TV high definition provides. While in the showroom, looking always on screen in this page.
Rear Projection LCD or plasma
screens Rear projection is the lowest initial costs, but often have higher costs over the life of the TV. This is because the projection lamps very expensive ($ 300 to $ 500) and must be replaced, about four or five years. The angle of projection screens tend to be poor. In other words, you have to sit in front of the screen to see the best picture.
Plasma displays are very popular and offer excellent color. Plasma looks better when viewed in a very dark room and viewing angle is excellent. The main disadvantages of plasma power consumption. plasma screen consumes nearly twice the energy of a Comparable size LCD.
LCD or liquid crystal displays use the same technology found in flat monitor.Until team recently in the LCD panel limited screen size. In other words, if you want a larger TV screen of 40 inches, he had to buy a plasma screen. LCD varies, and is not today.Other less than a factor of reduced energy consumption, the LCD and the production of better quality known, in part or in well-lit room. If you watch television, as in a complete dark room, probably work best plasma screens. For scenarios other types of lighting, focusing LCD screen.
Colors, brightness, contrast, refresh rate
You should be able to establish a very nice color of most televisions HD receive.Two market factors that influence the visual quality of television more than anything, the brightness and contrast.
Both factors, brightness and contrast can be misleading if the showroom. First, almost all electronic stores, increase the brightness in their showrooms. The same brightness level, you look terrible at home.
Secondly, the contrast ratio is often offered to manufacturers and are used with a bit of marketing hype. Contrast ratio is the difference between white and black levels. The problem is that several methods for determining the contrast ratio is difficult to compare apples with apples. Good contrast to produce darker blacks, bringing the colors are much more clearly shows does.Plasma have better contrast ratios than LCD or projection screens rear. Select the HDTV, which has rich colors and deep black. If you start in the Black focus when playing high-definition screen, you start to see the difference in the richness of color.
The refresh rate is how many times the entire image or image displayed on the screen per second. Most High definition televisions have Hz refresh rate, which means that the painted screen 60 times per second half. Some high-end TVs have a rate of 120Hz refresh. If you are just a lot of fast action movies and you will see fewer problems with motion blur with a 120Hz refresh rate.
Buying Tips
Shop around. There is strong competition in the market for HDTV. Other providers say, the more you learn is the perfect choice much easier.
Always check prices on retail sites before buying. Best Buy and other retailers often run sales both in its stores and website. We have seen the prices on the website, which is $ 200 and $ 300 lower for high-definition TVs, the distribution was commercial. Print a copy of the website and the camp. If we did that, got the lowest price on your website.
Make sure you understand the distance adequate vision and select a screen size that fits in the living room or home theater. While in the showroom, and away from the screen. You will see why is it good reading distance can make a big difference.
Have a salesperson to show you how the brightness and other video modes change before leaving the room exposure. You can try to sell at home calibration service, which costs an additional $ 150 to $ 500. If it is not hard to do when you know how to use these functions to set the menu on-screen TV. Many people find that a terrible spectacle of big-screen TV when you first turn it seems. This is because the video mode, and brightness are generally configured to showroom.
If you buy a Blu-ray and other high definition, do not let the seller make sure you buy a $ 100 + Monster Hdmi Cable to avoid problems. This is nonsense. Most $ 20 or $ 30 for cable Well.See HDMI works well as this: Heer and Heer
