This simple chart will tell you if those new 4k tvs are worth it for you.
simply look at how far you sit from your TV and this chart will tell you witch resolution is best for you.
average is 8 to 10 feet away making the 1080P tv the most common TV to own.
Below is a brief description on plasma TVs or LCD
sales people can give you this big talk about how high of a resolution a TV is and how crisp and clear it looks but when you take it home your never standing up next to the TV as you are in the store so keep that in mind.
Plasma
Plasma screens create an image by running an electrical current through tiny gas plasma cells that are held between two plates of glass.
The advantages of a plasma TV are:
- Superior color and brightness to LCD TVs
- Available in bigger sizes than LCD TVs
- Best for a wider viewing angle
LCD is short for Liquid Crystal Display. This technology works by back lighting the electrically-charged liquid crystal cells in the screen with a fluorescent lamp. LCD TVs could suit certain situations better, in that they are:
- Better for a bright room
- More compact, lighter weight and more portable than plasma TVs
- More energy efficient than plasma TVs
- Highly affordable
LED-LCD
Similar to LCD technology, LED-LCD technology replaces the fluorescent back lights with LED lights, resulting:
- Equivalent color and brightness to plasma TVs
- The most energy efficient TV on the market
- Lightest weight TV available
- Thin panels and sleek design - ideal for wall mounting
- A range of sizes available
Plasma television technology is based loosely on the fluorescent light bulb. The display itself consists of cells. Within each cell two glass panels are separated by a narrow gap in which neon-xenon gas is injected and sealed in plasma form during the manufacturing process. The gas is electrically charged at specific intervals when the Plasma set is in use. The charged gas then strikes red, green, and blue phosphors, thus creating a television image. Each group of red, green, and blue phosphors is called a pixel (picture element).
Although Plasma television technology eliminate the need for the bulky picture tube and electron beam scanning of traditional televisions, because it still employs the burning of phosphors to generate an image, Plasma televisions still suffer from some of the drawbacks of traditional televisions, such as heat generation and screen-burn of static images.
What advantages does plasma have over LCD? Apart from better contrast due to its ability to show deeper blacks, plasma screens typically have better viewing angles than LCD. Viewing angles are how far you can sit on either side of a screen before the picture's quality is affected. You tend to see some brightness and colour shift when you're on too much of an angle with LCDs, while a plasma's picture remains fairly solid. Plasmas can also produce richer, more natural colours, due to both light leakage and to a limit on the hues that LCD can reproduce.
What advantages does LCD have over plasma? Apart from becoming increasingly price-competitive, LCD has the edge over plasma in several other key areas. LCDs tend to have a higher native resolution than plasma's of similar size, which means more pixels on the screen.
LCDs also tend to consume less power than plasma screens, with some of the newer "Eco" LCD panels able to use half of the power than equivalent plasma's, with the trade-off being lower brightness.
In terms of bulk, LCDs are also generally lighter than similar-sized plasma's, making it easier to move around or wall-mount. This is because LCDs use plastic in their screen make-up, whereas plasma's tend to use glass.
LCDs have a longer lifespan than plasma screens. While this may have been true of earlier plasma models — which dropped to half-brightness at 20,000 hours — many modern plasmas have the same 60,000-hour lifespan as LCDs. This means that both types of TVs will last for almost seven years if left on 24 hours a day.
Recently, LCD arguably caught up to the quality of plasma with the introduction of LED backlighting . Instead of lighting the screen with fluorescent tubes, as is traditional, it uses banks of LED lights. There are two types of LED lighting: direct and edge. Direct back lighting means that the lights are mounted behind the LCD panel, while edge-lighting uses a series of LEDs along the edge of the screen. Most thin LCDs on the market use this edge-lighting, though direct lighting is arguably better for picture quality. Lastly, LED is not to be confused with OLED.
You might have also heard that plasma's suffer from screen burn-in, an affliction not commonly associated with LCDs. Screen burn-in occurs when an image is left too long on a screen, resulting in a ghost of that image "burned in". Newer plasma's are less susceptible to this, thanks to improved technology and features such as screen savers, but burn-in can still be a problem. However, after a few days most burnt-in images will fade — they are no longer permanent.
