PROJECTOR GLOSSARY

The most common resolutions are:

• VGA : 640 x 480 pixels
• SVGA : 800 x 600 pixels
• XGA: 1024 x 768 pixels
• WXGA: 1280 x 800 pixels
• SXGA: 1280 x 1024 pixels
• UXGA: 1600 x 1200 pixels
• Full HD:1920x1080 pixels
• HD ready: 1280x720 pixels

Contrast:

The level of contrast is established with a ratio of xxxxx :1, which is equal to the opposition of light intensity between the lightest and the darkest colours.

LCD or DLP technology?

LCD and DLP projectors are perfectly adapted to your presentations or your Home cinema.

3LCD Technology

Projectors equipped with LCD (Liquid Crystal Display)technology are made a.o. of three panels (red, green, blue) which enable the realization of the existing colours panel.

DLP or 3DLP Technology

DLP (Digital Light Processing) ) projectors contain a DLP chip made of numerous rotating micromirrors. Those can be oriented differently in order to reflect the light as precisely as possible.
The images projected by those videoprojectors can either be in different levels of grey or in colours. The shades of grey appear as the micromirrors approach or move away from the light source.
As far as the colours are concerned, they are formed as the light beam projected on the screen passes through a colour wheel before reaching the DLP chip which contains the micromirrors.

LAN :

LAN (Local Area Network) or local network.
It is a computer network: different computers, set in a quite small geographic space, are connected to each other (e.g.: inside a company, a building,…). Thanks to this local network, several computers can for instance share files, applications, printers,…
A projector can also benefit from this local network to allow the diffusion of your images and the control of the projector (switch on, switch off, change of source,…).

WIFI :

Wifi (abbreviation of Wireless Fidelity) is the term that was initially given by the Weca (Wireless Ethernet Compatibility Association) for the material which meets the standard 802.11 regarding wireless communication in an Ethernet network. In other words, WiFi technology enables to replace the traditional network cables in a determined area thanks to terminals sending radio waves. So, thanks to the WiFi it is possible to transmit and share information from your computer to your projector.

Fan noise :

The fan noise or noise level, generally mentioned in the datasheet of the projector, is expressed in Db (decibel). It is the noise generated by the fan of your videoprojector. In fact, every projector has a fan in order to reduce its inside temperature. A videoprojector is generally considered to be quiet when its ’fan noise’ is lower than 30 Db.
