Imagine you have a cheap torch bought from a garage. In a power cut at night, this will allow you to easily see your way around, but at midday on the beach, it will only illuminate things that are very close to you, if at all. So the ambient light in the area that you will project in, is the important factor regarding the brightness.
Typically, newer desktop projectors are between 1,000 and 4,000 Lumens. Professional projectors are usually more than 4000 Lumens up to the brightest available today, around 25,000 Lumens.
Hire Division desktop projectors for hire are all above 3000 Lumens.
With rear projection, you will need enough room behind the screen to position the projector at the right distance to ensure the image fits correctly, and the material is a special type of slightly transparent material. Most desktop projectors have lenses with a zoom to help with this, and of course, you will have to reverse the image, in order for it to be projected correctly. This can usually be seen in a menu in the projector.
There are currently two main types of video projector LCD and DLP. There are a couple of others, but there are very few models available. (LED etc)

- SXGA (1280×1024)
- HD READY (1280×720)
- WXGA (1366×768)
- WSXGA 1440×900)
- SXGA+ (1400×1050)
- UXGA (1600×1200)
- WSXGA+ (1680×1050)
- HD (1920×1080)
- WUXGA (1920×1200)
- WQXGA (2560×1600)
There are several others but they do not relate currently to smaller desktop projectors.
Generally, this tells you how detailed a picture will be. For powerpoint, XGA is usually preferable.
Some projectors have the ability to change lenses. A short throw lens allows the projector to be very close to the screen and still project a large image, and a long throw lens means that a projector can be very far away but still project an image that is not way to large. A formula can be used to calculate the distance from screen to projector, lens requirement and screen size. Our handy calculator is available for this.
