TERMINOLOGY

Anamorphic
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

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

Auto Programmable Scan
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.

Audio Swap
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.

Aspect Ratio
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.

Active Light Control
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.

Active System Control
Dynamically adjusts the video signal according to the image contrast. Working in tandem with Active Light Control, it adds greater brightness to bright scenes and brings more depth to dark scenes, delivering more vivid images.

ATSC & NTSC Tuner (ATSC - Advanced Televsion System Committee)
ATSC tuner is the main HDTV Digital Receivers for HDTV TV. Regular tuner is called NTSC tuner which receives the NTSC signals. In a few years time, NTSC signals will be slowly phased out in favor of HDTV signal. Therefore all tuner will be change to ATSC tuner.
Right now, all Digital TV requires separate NTSC & ASTC tuner to receive both NTSC & HDTV signal now.


Color Gamut
Color gamut is the range of red, green and blue the can be correctly rendered on a display. NTSC standards set a range of colors that can be transmitted. LCD panels that are able to display a higher percentage of NTSC color gamut are superior for watching television.

Contrast Ratio ( Dark Area Illuminance )
The brightness of a display at full white over the brightness of a display at full black. Because the black value is greatly affected by ambient light, some TV technologies calculate contrast ratio in darkened rooms. LCD televisions are superior at rejecting ambient light and maintaining contrast ratios in lit rooms.

Component Video Inputs
Delivers outstanding resolution and color accuracy of video images from a variety of sources, including DVD players, by keeping the Y, PR, PB of video images intact during the transmission process.

DSTN
Abbreviation of Dual-scan STN, an enhanced STN passive matrix LCD display. The screen is divided into halves, and each half is scanned simultaneously, thereby doubling the number of lines refreshed per second and providing a sharper appearance. DSTN is widely used on laptops.

DVD
Digital Versatile Disc – A high-density compact disc for storing large amounts of data, especially high-resolution audio-visual material. Movies stored on DVD are higher resolution than those stored on VHS videotape.

DVI
Digital Visual Interface – A type of standard connector between the display and a computer or other device. DVI is Video only. DVI images are superior to composite video and
S-Video signals.

DVI-HDCP
Used by newer HDTV set-top boxes and DVD players, the DVI-HDCP connection allows the transmission of uncompressed, copy-protected digital content to your high definition display with stunning image fidelity and clarity.

Five-Wire Resistive Technology
This technology utilizes the bottom substrate for both X and Y-axis measurements. The flexible coversheet acts only as a voltage-measuring probe. This means the touch screen will continue working properly even with non-uniformity in the coversheet's conductive coating. The result is an accurate, durable and reliable touch screen that offers drift-free operation. It is tested to over 35 million finger touches with no performance degradation (compare to 1 million touch life max. for Four-Wire and Eight-Wire Technology). Moreover, this advanced design allows flat, spherical (not available in Four-Wire and Eight-Wire), and cylindrical designs. Furthermore, Resistive Touch Screen Panel can be used with any object to touch, e.g. finger, pen, pencil, credit card, and many others. On the other hand, Capacitive Touch Screen Panel only allows to use finger to touch, which uses your body as a ground to measure coordinates.

Flicker and Static Free
With Sceptre's feature, "Flicker and Static Free", it is friendlier and healthier for the users. Lots of people found those two are annoying and unhealthy to use in an extensive use. Screen Flicker results from a variety of factors, the most important of which is the monitor's refresh rate, the speed with which the screen is redrawn. If the refresh rate is too slow, the screen will appear to glimmer. Screen Static is the noise produced in a radio or television receiver by man-made electrical disturbances.

HDTV Resolution
480i (Interlaced), 480p (Progressive), 720p (Progressive) & 1080i (Interlaced).

HDTV Ready
A television set that is equipped to receive a digital signal form an external high definition digital source, like a cable box, satellite, or tuner.

HDMI-HDCP
HDMI is a new standard digital connection between A/V devices, such as a set-top box, DVD player or A/V receiver, and a digital television. HDMI stands for High-Definition Multimedia Interface, and like DVI, it allows for the uncompressed data transfer of video between a digital TV and HDMI-enabled consumer electronics devices.

According to the HDMI’s official Web site, the advantages of HDMI are:
1) The highest quality video seen and audio heard
2) Fewer cables behind the TV means less mess and confusion-free connection
3) Automatically configures remote controls of devices connected by HDMI
4) Automatically adjusts video content to most effective format
5) HDMI is compatible with DVI, which means it will allow connection to PCs

Horizontal /Vertical Edge Correction
Sharpens the edges of objects in the picture. Horizontal edge correction works in conjunction with the dynamic sharpness control and velocity modulated scan to help produce clean, crisp television images and reduce the unwanted effects of video noise. The vertical edge correction circuit works in conjunction with the digital comb filter to sharpen the horizontal edges of objects in the picture.

Horizontal Viewing Angle
A wide horizontal viewing angle lets viewers sit away from the center seating position and still experience the product.

HPA
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.

LCD
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.

Light weight and slim design
With Sceptre's Light Weight and Slim Design features, it is ideal to carry for the road trip, business presentation, and many other purposes. This product has an easy detachable base (no tool required³). This feature reduces the unnecessary weight and space to carry for the presentation. Most of all, it is to carry around.

(PIP) Picture-in-picture
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.

Resolution
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.

8ms, 12ms, 16ms & 25ms Response Times
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.

TFT
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.

S-Video
This input is used on most electronic devices, allow a signal line and sound signal connection.

Super MVA technology
The conventional multi-domain vertical alignment (MVA) technology has smaller viewing angle in the azimuth angle of 45 degree.
The viewing angle of MVA LCD is increased to 80 degree in all azimuth angle by CMO' Super MVA technology
In layman's term, MVA equal wider viewing angle from the both sides of LCD.

Video In
