The most important thing about television: LCD (with LED), Plasma and CRT compared


Question format : 16:9 or 4:3 - which is better?

Almost all new flat screen televisions have the 16:9 format and that is a good thing : Last TV programs are broadcast in 4:3 format, and their number continues to decrease . 4:3 refers to the aspect ratio of height and width of the image . A 4:3 4:3 TV shows images of optimal size. A 16:9 wide screen displays images in either 4:3 with black bars left and right , cuts up and down slightly from the image content or distorts them .

advantage 16:9

TV movies and football broadcasts and DVD movies usually have a widescreen format. Also, more and more TV shows, such as news , converted to this format. 16:9 TV show this - as opposed to 4:3 devices - without interfering beams and undistorted. Movies in Cinemascope format (often Hollywood movies ) have even on a 16:9 TV , black bars top and bottom . But falling considerably narrower than 4:3 devices . For the TV purchase applies: The new device should have a 16:9 screen .

Special case 21:9 TV: should we forget the special cinema format in which , for example, Philips offers several television. The extra-wide device type is for TV fans , who often watch movies in 21:9 format. When displaying 16:9 content , hide the TV left and right black bars or distort the image .

How big should my TV?

The decisive factor is the viewing distance . Rule of thumb : For the perfect visual impression of the distance to the TV set should be about three times as large as the screen size , with a 100 -inch diagonal or about three meters. If you sit too close to the screen , the movie experience - as in the first movie series - quickly exhausting : You begin to look to the left and right of the screen to mitzubekommen the whole event . Also contributes to a close viewing distance aberrations fall on faster .



Flat screen or tube TVs ?

CRT TVs have disappeared from the shelves , the major manufacturers have all withdrawn from the business.

LCD or plasma ? Or LED ?

Flat-panel TVs up to 82 inches diagonal there is nearly exclusively with LCD technology. From a screen size of 94 inches , you have the choice between LCD or plasma : With normal television (PAL ) and DVD movies offered good plasma have a slightly better picture quality than comparable LCD sets . Good LCDs display movements today but also liquid and the black almost as dark. In the natural colors of plasma television but still have the lead. Another advantage : The presentation also looks from the side of even more brilliant . Who sits diagonally in front of an LCD , looks often ( depending on model) with a milky image lackluster colors.

The term LED TV is used by some manufacturers misleading - when the devices are simple to LCD TVs that use LEDs as the light source instead of fluorescent tubes . This usually has advantages in power consumption , but not necessarily in image quality - at least in theory. Since higher class LCD TVs all set today to LED technology , so that a better display quality is actually connected .


disadvantage of plasma

Long motifs shown can leave shadows that disappear after a while. Or, are also seen in the worst case permanently in the background. Plasma are therefore less suitable for games consoles or PC connection. With some exceptions, they also have a reflective windscreen , can interfere with reflections on the in bright rooms.

Features of LCD TVs ( with LED)

LCD televisions have often had a dull windshield. Newer devices but are also usually equipped with reflective screens , which can have advantages for the luminosity of colors. If you are sensitive to reflections , you should steer clear of these devices anyway. Since LCD TVs can shine brighter , they deliver brilliant pictures in daylight rather than plasma. In well-lit showrooms LCD devices therefore see better. For the movie night in the darkened living room but may be the better choice a plasma. Since the quality of a television is heavily dependent on each model , tests show only AUDIO VIDEO FOTO BILD how well a device really is. In each test table also contains the respective values ​​for the lateral viewing angle and the reflectivity of the screen.

How many pixels does a TV?

The regular program is radiated with 720x576 pixels (PAL). Most tube devices can accurately represent these pixels number. With LCD TVs , the screen resolution is usually 1920x1080 pixels, favorable or older models may also have 1366x768 pixels. Plasma devices also have 1920x1080 pixels usually . Flat-panel televisions have to convert the image signals corresponding to detailed images . For a good TV picture quality are therefore not the number of displayable pixels decisive but the quality of the electronic image .

TV with 1920x1080 pixels (often called Full HD) have some problems with standard TV to show accurate images because they have to expect more pixels. Only with HDTV signals with 1920x1080 pixels, they reveal their true ability .

Antenna , cable or satellite - which provides the best TV signals ?

Whether or flat- tube TV , via analog cable and digital terrestrial television (DVB -T reception boxes from 50 euros ) show the devices rather mediocre quality. There's a better picture with digital cable TV via a DVB - C receiver or via satellite TV via a DVB-S receiver. Tip: To play the quality advantage , you should transfer the image signals an additional receiver via an HDMI cable to the TV . Lacks an HDMI jack , use a YUV or RGB Scart connection. DVB- C and DVB -S , you can also receive high-definition television (HDTV ) that is transmitted exclusively via HDMI cable.
