120Hz Technology can improve the clarity of a HDTV especially in a Fast Motion, Speedy environment. HDTV with the 60Hz Technology has a blueness to the image when it is showing Fast Motion images.

Television images are created with a stream of still images. In the US, the stream is 60 fields each second. As two fields are needed to make a complete frame or image, the frame rate is 30 per second. In Europe, the rate is slightly slower, at 50 fields and 25 frames per second. As 30 or 25 frames per second is fairly slow, there can be a noticeable flicker and movement can look jerky as well. This is more of a problem in Europe than the US because of the slower frame rate in Europe. The frame rates were chosen years back according the mains supply frequency in the US and UK. Although this is no longer of any concern, with advances in elecctronics, the frame rates have stuck. Even with the move to high definition, the frame rates remain the same - 60Hz in the US and 50Hz in Europe. All other countries, by the way, follow one of the two frame rates.

The 120Hz or 100Hz displays aim to overcome the flickering and jerky movement by inserting a new field between each of the fields received by the television. The theory is that with 100 or 120 fields being displayed each second, the human eye cannot discern the discrete images and see only a smooth picture. For static and slow moving images, the theory works well but as with all engineering solutions, this isn't a perfect one in all cases...

Each field that is inserted needs to be made up. It cannot be a copy of the previous field because it would result in two identical fields, returning the output to 60 or 50 Hz. So, the new, intermediate field has to be calculated by taking the previous and the following field and working out what the image would be, if there was an original field at that time. It's a process called temporal interpolation and needs a huge amount of processing power. Sometimes, the calculations to generate the new field can get confused and the result is a disturbing judder in some parts of the image. Broadcasters who have to use similar techniques will spend a great deal of money to get the best conversions and domestic televisions will never have the same level of hardware installed.

These errors are rarely visible, but before spending a lot of extra cash on a 120Hz television, spend some time looking at the image. Look for fast pans across football supporters as the camera follows the ball, for example. Also look at fast scrolling text. These are the images that may cause problems. If you are happy with the image you see and it looks smoother than the 60Hz equivalent model, then it's a good buy. If it doesn't look smoother, you should ask yourself if the extra cost of a 120Hz television is worthwhile.

Anamorphic describes a method used for squeezing 30-40% more wide screen resolution onto a DVD movie. Wide screen DVD movies can present more of the original theatrical format with a superior image. Adjust the DVD player’s output to 16:9 for wide screen for peak performance   

Controls the sound level to prevent wide variations in volume among different TV Channels and types of programming.  

Automatically tunes all available channels in your area or cable system into memory, and then lets you add or delete the channels of your choice. 

The ability to listen to the audio from the main screen or the picture-in-picture window, without moving the video image around on the screen.

The term "aspect ratio" describes the relationship between the width and height of a TV screen. Traditional TVs have an aspect ratio of 4:3, meaning that for every 4 inches of width, there are 3 inches of height. This results in a screen that looks almost like a square. Many newer TVs have an aspect ratio of 16:9, so their screens are almost twice as wide as they are tall. Also referred to as "wide screen," 16:9 TVs are better suited to wide screen DVDs and HDTV broadcasts. The term "aspect ratio" can also be used to describe the dimensions in which film or TV shows are shot. Traditional broadcasts are usually in 4:3 format, while HDTV broadcasts have an aspect ratio of 16:9.

Automatically detects the brightness levels of the input signal and adjusts the backlight accordingly. It provides a maximum brightness that's considerably greater than the level of conventional systems, resulting in crisp, natural pictures.

Short for High-Performance Addressing, a Passive-Matrix Display technology that provides better response rates and contrast than conventional LCD displays. Although HPA displays aren't quite as crisp or fast as Active-Matrix (TFT) displays, they're considerably less expensive to produce. Consequently, HPA is being used by a number of computer manufacturers for their entry level or value notebook computers.

Abbreviation of Liquid Crystal Display, a type of display used in digital watches and many portable computers. LCD displays utilize two sheets of polarizing material with a liquid crystal solution between them. An electric current passed through the liquid causes the crystals to align so that light cannot pass through them. Each crystal, therefore, is like a shutter, either allowing light to pass through or blocking the light.

An enhanced version of picture-in-picture offers a variety of per-arrange formats that the user can choose from to display more than one image on a screen. Some are arrange to display simultaneous image from both a computer and TV. 

Refers to the sharpness and clarity of an image. The term is most often used to describe monitors, printers, and bit-mapped graphic images. In the case of dot-matrix and laser printers, the resolution indicates the number of dots per inch. For example, a 300-dpi (dots per inch) printer is one that is capable of printing 300 distinct dots in a line 1 inch long. This means it can print 90,000 dots per square inch.

For graphics monitors, the screen resolution signifies the number of dots (pixels) on the entire screen. For example, a 640-by-480 pixel screen is capable of displaying 640 distinct dots on each of 480 lines, or about 300,000 pixels. This translates into different dpi measurements depending on the size of the screen. For example, a 15-inch VGA monitor (640x480) displays about 50 dots per inch.

UXGA: A display with 1200 x 1600 pixel resolution.
SXGA: A display with 1280 x 1024 pixel resolution.
XGA:   A display with 1024 x 768 pixel resolution.
SVGA: A display with 800 x 600 pixel resolution.
VGA:   A display with 640 x 480 pixel resolution.

Printers, monitors, scanners, and other I/O devices are often classified as high resolution, medium resolution, or low resolution. The actual resolution ranges for each of these grades is constantly shifting as the technology improves.

Video RAM Required for Different Resolutions

Response time is a measure of how long a display takes to change the image. A typical LCD television is 2 to 3 times faster than the average computer monitor LCD Fast response time is superior for playing computer games and viewing action movies and sports using TFT technology.

Abbreviation of Thin Film Transistor, a type of LCD flat-panel display screen, in which each pixel is controlled by from one to four transistors. The TFT technology provides the best resolution of all the flat-panel techniques, but it is also the most expensive. TFT screens are sometimes called Active-Matrix LCDs.
