A standard for measuring light output, used for comparing projectors. Unfortunately, there are enough variables, that the eye will often disagree radically with the ANSI rating. If however one projector uses halogen lamps and another metal-halide, the halogen projector will seem noticeably dimmer even if the two units rate the same. Other variables, including type of LCD technology (TFT LCD, Polysilicon LCD), type of overall technology (LCD vs.DLP vs. CRT), contrast ratios, etc. all effect the end result.

The contrast is the relationship between the brightest possible output, and the darkest possible output.

All projectors have a native or true resolution. This is the standard but most projectors support other resolutions. A projector is best viewed in the standard resolution.

Shows if the projector supports real widesceenformat 16:9 its important for homecinema users.

Indicates if the projector has digital zoom or not.

Full-HD innebär att TV:n har 1920x1080 pixlar. Vilket betyder att projektorn har en upplösning på cirka 2 megapixel.

En "vanlig" HD-ready TV har en upplösning som kan variera. Men för det mesta handlar det om en upplösning på 1366x768 pixlar eller 1024x768 pixlar. Det betyder att en sådan TV har en upplösning på cirka 1 megapixel eller strax under det.

Skillnaden mellan en full-HD-TV och en vanlig HD-ready-TV är inte särskilt stor när du tittar på HDTV. En vanlig TV-tittare kommer troligen inte märka någon skillnad. Den enda gången som en full-HD-TV idag är bättre än en vanlig HD-ready-TV är när det gäller att visa filmer via en Blu-ray eller HD-DVD-spelare.

A connector for a computer cable in which the plug and socket are D-shaped so they only fit together one way. DB connectors are often used for serial ports. DB-9 connectors have 9 pins and are used to connect a mouse.DB-25 connectors have 25 pins and are used to connect a printer. DB-15 has 15 pins and is used as a VGA connection to monitors.

Short for Super-Video, a technology for transmitting video signals over a cable by dividing the video information into two separate signals: one for color (chrominance), and the other for brightness (luminance). When sent to a television, this produces sharper images than composite video, where the video information is transmitted as a single signal over one wire. This is because televisions are designed to display separate Luminance (Y) and Chrominance (C) signals. (The terms Y/C video and S-Video are the same.)

To use S-Video, the device sending the signals must support S-Video output and the device receiving the signals must have an S-Video input jack.

The three-jack (RCA/Phono) component video connection splits the analogue video signal into three parts (one brightness and two color signals). Component video has increased bandwidth for color information, resulting in a more accurate picture with clearer color reproduction and less bleeding (better than S-video or composite video).

Special wide-bandwidth component video connections are capable of carrying wider bandwidth video signals, like progressive-scan DVD and High-Definition digital television. All HDTV-ready TVs include at least one set of wide-bandwidth connections for connecting a separate HDTV tuner (or progressive-scan DVD player). A component video connection can carry high bandwidth signals up to 1080i and 720p.
