    K comu je takyto clanok
    Ku kvalitnemu televizoru je potrebny aj kvalitny zdroj signalu, co vacsina ludi doma zabezpecene nema. Kupia si telku za 1500-2000 eur a potom sa doma cuduju preco maju obraz horsi ako pred 20-timi rokmi, lebo maju este kablovku s analogovym signalom, pripadne s digitalnym s bitrate horsim ako videa na youtube. Uz chyba v clanku len spomenut 3D...ciste predvianocne PR. Kupovat plazmu neopdp, ktora s uhloprieckou 42'' spapa 340 W....to sme sa ale posunuli dopredu, uz sme odstranili neduhy uz to nezerie 600 W uz len 340 W LOL ...cista ekologia...hlavne, ze sme museli vymenit ziarovky za usporne.

    Nie tak celkom

    Nekvalitny (analog) signal, zobrazovany na LCD je pre masochistov (neostre, rozmazane, zliate farby, voskove tvare), na plazme je pozeratelny. Pri kvalitnom sa rozdiely zmensuju, plazma ma vsak navrch (ostrost, rychlost odozvy, jas a farebny ton z uhla...)

    Mám z tej série, ale len 32LE5300 a kvalitou obrazu som bol milo prekvapený, aj menej kvalitný DivX veľmi dobre zobrazuje, čo je na starej LCD-čke "kockodrom", to 5300ka dobre upscaluje. Za fullLED by si si priplatil, čo sa týka kontrastu, tak údaj 3mil:1 hovorí za všetko. Má aj ocenenie EISA.

    Vyborne, dakujem ti (aj Fanatixovi). Na tie hry som sa pytal preto, ze synom vadila pomala odozva nasho starsieho LCD (LG 42LB5D). Ja sice strielacky nehravam, ale uz sa tesim ako si zalietam.
    No a samozrejme, tesim sa aj na filmy na nom (ale to az neskor)

    ja zase nie som uplny maniak do hier, ale sem tam si zahram a obraz sa mi zdal velmi dobry, a na filmy je tiez ok, daju sa najst mozno aj malicke chybicky v obraze, tj netreba cakat uplnu dokonalost hlavne co sa ciernej tyka, ale je to vsetko v urovni ktora sa da akceptovat v danej cenovej hladine a v kazdom pripade ja som spokojny, treba sa hlavne pohrat s nastaveniami:-)

    Rada

    Ako vidím, že niektorí máte určité skúdenosti. Chcel by som poradiť pri kúpe nového TV. Daný TV by mal mim. splňať tieto podmienky aby bola čo najlepšia kvalita . Čiastočne som obmedzený prietorom. Max. šírka prijmača 110 cm. Maximálna hlbka TV prijmača ( od steny konzola +TV) 28 cm. TV zavesený na stene. Cena cca 500 euro. Príjem cez digitá. tel. Magio - kabel (internet+telefon). Dúfam, že mi poradíte ten správny prijmač. Dik.

    no čeče, to skôr LG je pre socky. LG, ako bývalá značka Goldstar, veľa kvality nepobral. Aj keď treba priznať, že na rozdiel od situácie spred takých 2-3 rokov sa kvalita tejto značky zlepšila.

    ja nehovorím, že LG má zlý obraz, práve naopak. Iba to, že LG je smiešne, že sa z iných smeješ, že sú socky, a kúpil si si LG a chváliš sa, ako by si mal nejaký TV Loewe alebo SHARP s Quattron obrazovkou a technológiou local dimming. Nože napíš model, či nemáš len edge LED. A čo sa týka môjho názoru na vyhadzovanie peňazí za drahé TV, tak čítaj môj príspevok nižšie. Dnes si si mohol kúpiť relatívne slušný LCD TV, a za tri roky za ušetrené peniaze LED TV s local dimmingom a full LED podsvietením, ktoré bude úplný štandard, a ešte aj väčšou uhlopriečkou.

    ja sa smejem z plaziem za 500€.. za 1000-1100€ sa da kupit velmi slusny Led Lcd a to nie je taka vysoka suma aby zruinovala rodinny rozpocet.A na margo toho ze LG je byvaly Goldstar, co vsetcia vieme, je to uplne irelevantne nakolko odvtedy uz pretieklo celkom dost vody a situacia je uplne ina.

    je to tvoj názor, ja ti ho neberiem. Pokiaľ si s kúpeným TV spokojný, tak to bola pre teba dobrá kúpa. Pokiaľ by som to však mal zovšeobecniť, keď už kvalitný LED panel, tak s technológiou local dimming a nie s edge LED podsvietením (ktoré lacnejšie modely Samsungu, LG alebo Sony majú zväčša všetky). Alebo sa miesto toho dať 1000€ za nie špičkový LED, tak radšej kúpiť za 500€ plazmu alebo LCD. Za ďalšie tri roky si za zvyšných 500€ kúpiš TV, ktorý bude parametrami o dve triedy lepší ako ten dnešný za 1000€ - výhody: budeš mať dva TV (druhý môžeš dať do detskej spálne alebo podarovať rodičom, ak majú ešte staré CRT). A ak sa aj TV pokazí (viď môj príspevok nižšie), nebude ťa to tak mrzieť, okrem toho budeš mať ešte druhý prístroj do rezervy.

    LCD TV vs. Plasma

    This is the #1 question for me at any dinner party: Which is better, LCD TV or Plasma? This is a much debated topic and a fun one. When choosing between plasma and LCD TVs, you're actually selecting between two competing technologies, both of which achieve similar features (i.e., ,bright crystal-clear images, super color-filled pictures) and come in similar packages (i.e., 1.5 to 4 inch depth flat screen casing). To complicate the decision-making process further, price and size are two previous considerations that are rapidly becoming non-issues as LCD TVs are now being made in larger sizes and at competing prices with plasma.

    Despite their similarities, the two technologies are very different in the way they deliver the image to the viewer.

    Plasma technology consists of hundreds of thousands of individual pixel cells, which allow electric pulses (stemming from electrodes) to excite rare natural gases-usually xenon and neon-causing them to glow and produce light. This light illuminates the proper balance of red, green, or blue phosphors contained in each cell to display the proper color sequence from the light. Each pixel cell is essentially an individual microscopic florescent light bulb, receiving instruction from software contained on the rear electrostatic silicon board. Look very closely at a plasma TV and you can actually see the individual pixel cell coloration of red, green, and blue bars. You can also see the black ribs which separate each.

    Whether spread across a flat-panel screen or placed in the heart of a projector, all LCD displays come from the same technological background. A matrix of thin-film transistors (TFTs) supplies voltage to liquid-crystal-filled cells sandwiched between two sheets of glass. When hit with an electrical charge, the crystals untwist to an exact degree to filter white light generated by a lamp behind the screen (for flat-panel TVs) or one projecting through a small LCD chip (for projection TVs). LCD monitors reproduce colors through a process of subtraction: They block out particular color wavelengths from the spectrum of white light until they're left with just the right color. And, it's the intensity of light permitted to pass through this liquid-crystal matrix that enables LCD televisions to display images chock-full of colors-or gradations of them.

    LED TVs are a new form of LCD Television. The panel on an LED TV is still an LCD TV panel and operates the with the same twisting crystals matrix. The backlight is the difference - changing from flourescent to LED (light emitting diode) based backlighting. See our complete coverage of LED TV articles and models here.

    PICTURE QUALITY CONSIDERATIONS

    CONTRAST / BLACK LEVELS
    How to Calibrate Your HDTV

    Plasma technology has certainly achieved quite high contrast ratios, a measure of the blackest black compared to the whitest white. Many plasma display manufacturers boast a contrast ratio of 40,000:1 these days though our tests using a standardized ANSI checkerboard pattern have not proven these numbers out. Plasma displays achieve such impressive black levels by using internal algorithms to block the power to particular pixels in order to render a pixel "dark" or black. While this can limit a plasma television's gray scaling, it does produce exceptionally black blacks - depending on the manufactured plasma display element (i.e. glass). A plasma TV uses maxi

    power when it is producing full white. As a result, some 2nd tier manufactured brands of plasma TVs have an audible buzz or whining sound when displaying white or very light images.

    LCD (liquid crystal diode) displays, by contrast, utilize electric charges to twist and untwist liquid crystals, which causes them to block light and, hence, emit blacks. The higher the voltage passing through the liquid crystals in a given pixel, the more fully those crystals untwist and effectively block light - all of which makes these pixels darker. As opposed to plasma, LCD TVs use the most power when displaying a very dark or black image. This is a difficult process, and despite recent improvements in LCD black levels, only the best LCD televisions have managed to come close to plasma technology in contrast ratio. The one continual drawback here for LCD is off axis viewing, when black levels consistently drop. We have noted some improvement from LCD manufacturers lately in off axis viewing contrast.

    ADVANTAGE: Closer than a year ago, but still Plasma. LCD TV manufacturers have made great improvements in black levels and in many cases have nearly managed to match the contrast ratio of plasma TVs. However, Plasma displays still maintain a clear advantage in this category due to fading blacks when viewing LCDs from off axis. For scenes with a lot of dark and light images shown simultaneously - as with content originating from DVDs, video games, and NTSC TV signals - plasmas still consistently outperform LCD TVs.

    COLOR ACCURACY

    In plasma displays, each pixel contains red, green, and blue elements, which work in conjunction to create 16.77 million colors. Insofar as each pixel contains all the elements needed to produce every color in the spectrum, color information was more accurately reproduced with plasma technology than it was with other display technologies. The chromaticity coordinates were more accurate on most plasma displays. Though the color saturation resulting from the pixel design of plasma displays is remarkable, LCD technology has nearly caught plasma in gray scaling color accuracy. Plasma continues to exhibit more richness in color information and more natural coloration. Today, SMPTE color coordinates in top plasma displays still normally outperform those in LCDs, which tend toward oversaturation.

    LCD TVs reproduce colors by manipulating light waves and subtracting colors from white light. This is an inherently difficult template for maintaining color accuracy and vibrancy - though most LCD TVs manage quite well. While color information benefits from the higher-than-average number of pixels per square inch found in LCD televisions (especially when compared to plasmas), LCDs are simply not as impressive as plasmas with similar pixel counts. LCDs however, produce a typically brighter picture. Greens sometimes look oversaturated and reds can run a bit warm, but in a room with lots of ambient light coming in from windows, an LCD TV would be my choice.

    ADVANTAGE: Preference to plasma but depends upon room light, manufacturer and model. Plasma TV color richness and naturalness will prevail in rooms with lower to normal lighting. LCD TVs perform better in very brightly lit rooms due to their inherent anti glare technology and brightness.

    VIEWING ANGLES

    Plasma manufacturers have made much of their near perfect 180 degree viewing angles, which is about as good as horizontal and vertical viewing angles get. This owes to the fact that each pixel produces its own l

    light, rather than light being spread across the screen from one central source. Hence, each pixel is more readily visible because its brightness is consistent with every other pixel on the screen. One consistent area of superiority of plasma viewing angles is demonstrated when viewing dark material content, especially DVDs. A Plasma display holds the black levels from off axis, while LCD TVs lose black level intensity/contrast more as the angle off axis increases. This usually occurs after around 45 degrees off center.

    LCD TV manufacturers have done much to improve their displays' viewing angles. The substrate material on newer-generation LCD models by Sharp and Sony has helped to expand those units' viewing angles, though they still have some ground to cover before catching plasma. Expect the best LCD HDTVs to have around 120 degree viewing angles.

    ADVANTAGE: Plasma

    FUNCTIONAL CONSIDERATIONS

    COMPUTER USE

    Generally the performance should be about the same in terms of displaying the video image provided that the resolution of the plasma or LCD TV is 1080p or higher. Some plasma TVs still have 720p resolution and this would be a drawback to a defined static image.

    Burn in is the second factor. Though plasma TVs have substantial anti-burn in technology built in these days, there is still some risk there.

    ADVANTAGE: LCD

    FAST-MOVING VIDEO PLAYBACK

    Plasma technology gets the easy nod here because of their excellent performance with fast-moving images and high contrast levels. It's an inherent quality of the technology. There are still some 2nd tier plasma manufacturers whose plasma TVs display some phosphor lag, a drag time in scenes changing from bright to dark.

    While the "response time" of LCD TVs has markedly improved in the last couple of years, they still suffer from a slight "trailer" effect, where the individual pixels are just slightly out of step with the image on the screen. During fast moving scenes, the most discerning eyes can detect this slight motion response lag. Motion lag may also be detected on LCD TVs when the camera pans from side to side sometimes appearing to stutter or jerk. This applies to both flourescent backlit LCDs and LED backed LCDs.

    LCD TV manufaacturers have worked hard to overcome the motion lag issue. Last years models saw the introduction of 120Hz refresh rate (up from 60). This year many models were introduced with 240Hz refresh rate. This refresh rate has drastically improved the response time. However, it also introduces unwanted video information by sharpening the picture background information and taking out necessary blur. This may seem like a positive, but with 90% of your viewing material, it is not. Depending upon the manufacturer, we advise turning off the 120Hz or 240Hz feature with all but live sports programming. See our full article about 120Hz/240Hz refresh rate here.

    ADVANTAGE: Plasma

    HIGH ALTITUDE

    There is a reason LCD flat panels are the preferred visual display units for use on airplanes: LCD TVs aren't affected by increases or decreases in air pressure. Their performance is consistent regardless of the altitude at which they're utilized.

    This is not the case for a plasma. The display element in plasma TVs is actually a glass substrate envelope with rare natural gases compressed therein. So, at high altitudes (6,500 feet and above), an air-pressure differential emerges, which causes plasma displays to emit a buzzing sound due to the lower air pressure. This noise can sound rather like the humming of an old neon sign. NEC has been effective in producing several plasma mod
