There are over 300 models of projectors on the market.Projectors are usually compared using four main factors: brightness, resolution, aspect ratio, weight.
To make a decision how bright a projector should be, first you need to consider the following factors:
The ability to control the light in the room
Providing that you plan to use the projector in an area where there will be lighting or there aren't any curtains to block out the natural light, it is recommended to choose a bright projector.
At home, people are advised to use projectors in a dark room to enjoy their own cinema experience to the full.
The more people are in the room, the bigger screen will in need to ensure everyone can see.
Increasing the size of the picture will typically require the projector to be situated further away from the screen reducing the image brightness as the light is spread and travelling over a bigger area.
The resolution is the number of pixels that make up an image. The larger the number of pixels the higher the resolution as well as the sharper and more detailed the image is.
There is a range of resolutions available: Projectors are compatible with different resolutions, converting different input resolution to the native output resolution. This process is called 'scaling'.
Projectors are used common in events, particularly in conferences and meetings where documents or any other types of data were on screen so that audience can follow the information.
