FAQ's (Guide to which projector to choose)
There are literally hundreds
of different models available, prices range from one, two, three and even
four thousand pounds, it may seem a daunting task to know what to buy, but
its not. There is one important question you should ask yourself, "What
will I use it for?"
Once decided, Your next consideration should be specification, which generally come into two categories, resolution and brightness, the second is less of an issue these days as most projectors are around a 1000 lumens, which is more than adequate for presentations in a small to medium sized rooms, classrooms and halls, even in well lit conditions. You will have to pay for increased resolution however. Most laptop computers up until 2000, were SVGA resolution, which is 800x600 pixels, however many later laptops and all desktops are XGA resolution 1024x768 pixels. This is not a problem for SVGA projectors, which will generally automatically lower the resolution, however if you are projecting high resolution photos and want near photographic detail, then it will have to be an XGA. If the projector is going to be used to project Video, i.e. from a sky box or video, then there is little to be gained from the higher resolution XGA since SVGA can already project an image consisting of over 800 lines which is more than the resolution of a video signal.
