Video Projector Guide
Color Depth
Color depth states how good the LCD represents color. It's the number of colors a monitor or an LCD panel is able to show. A good color depth is 16-Bit; although 24-Bit is strongly advised, this is the color depth that most high end projection panels have.
Lamps
An important thing to investigate is the type of lamp used. Check the replacement price of lamps and life expectancy. It would make you no good if you purchase a low price projector and later find out that every lamp replacement will cost you 400$. New lamp models can work for a minimum of 10,000 hrs.
Brightness
Brightness output is expressed in lumens. The higher the lumens the better the image is displayed in less than perfect lighting conditions. Some new projector models can display a vivid image even with the light on. 2000 lumens is a good choice for home use. Choose 3000-4000 for presentation theaters and jobs that require a bright image in a not too darkened room. Lumens rating of below 2000 such as the low priced 1300 models will have to be operated in a completely darkened room (Pitch Black).China solar panel catalog and Solar Panel manufacturer directory.
Connections

Long throw/Short throw projection
It's important to decide where you are going to place the projector. If the projector is going to be placed in front of an audience then you will need a short throw projector. And if you need to fix the projector some where behind the audience (Far from screen) you will need a long throw projector. What happens when you use short throw projector for a behind the audience application is that the image will be too large to fit on screen, and if you use a long throw projector for short distances you will get a very small and unclear image.
DIY Projectors
Well this is interesting. Did you know that you can build a projector yourself, it's not that hard really and it will cost you a fraction of retail prices? You should have basic knowledge with DIY projects. The image quality is very good you won't believe it. Though some patience is required in order to complete the projector.
