Large processors ‘Telico’ can not be qualitatively transform and stretch the analog terrestrial signal on the big diagonal. When viewing a digital signal from dvd to ‘box’ with a diagonal greater than 40 “will be noticeable lack of permission. Plasma technology is much better adapted to display broadcast signal than standard lcd. Image of the plasma more similar to the image created by the crt TVs, it is more saturated colors. Plasma cheaper than LCDs. However, the plasma has some significant drawbacks. The large size of pixels that create the image may distort the picture when watching at close range.
Fading points with insufficient frequent changes in personnel may become an unpleasant surprise for the owners of the plasma. This is especially noticeable when watching live channels, which are still putting their logos in the corner of the screen. Therefore, in built special devices that restore burnt pixels, but this does not always help. Serious shortcoming of plasma – a much larger (2-3 times), power consumption than lcd TVs. Disadvantages ”: expensive and unusual after crt TVs for the eye image.
Given the above to solve the problem how to choose a tv can be recommended: 1) To view the live channels and a dvd does not make sense to buy TVs over 40 inches. 2) If you want to save, you can buy a plasma panel, but keep in mind that saving on the price you’ll pay more for light, and you will have to closely monitor the burn-out pixels. However, if it is not necessary to choose TVs over 40 “, why then global brands invest in scientific and engineering research and has already achieved production of 70” panels? The answer is simple – hdtv. Owners of tv sets, supports hdtv (High Definition Television or hdtv “) called it” a window into another world. ” The difference between dvd and hdtv images can only be compared with the difference between vhs and dvd. HD-Ready and Full-HD resolution screen differ. When buying a tv with hdtv should be remembered that the vertical resolution ‘telly’, claiming to be HD-Ready, shall not be less than 720 stitches. Usually it is 1366×768. For ‘box’ Full hd – 1,080 stitches, usually 1920×1080. Important note: Full hd tv is uniquely equipped to be input hdmi, allowing him to apply for external signal Full hd (1920×1080). Beware of imitations: fraudsters can put an icon Full hd, even if no such entry. In this case, the Full hd signal, you can only get from a digital Full hd television, which entered into Russia does not yet appear. hdtv signal source can be three types of devices. Invented by Sony’s Blu-ray is not very relevant to our market because of high prices of CDs with recordings (more than $ 50) and players (the cheapest Blu-ray player costs more than 15,000 rubles). Common way – to view hdtv on a computer equipped with a video card with hdmi output. And finally – the media receivers. The advantage of media receivers – Low price (from $ 300 depending on the manufacturer). How to choose a tv? Importantly, be able to distinguish between the lcd from a plasma, and thoroughly explore the options list, which has a particular model.
