A projector is a device that integrates a light source, optics system, electronics and display(s) for the purpose of projecting an image from a computer or video device onto a wall or screen for large image viewing. There are hundreds of products available in the market and they are differentiated by their resolution, performance and features. These devices can be attached to a computer or video device just as you would connect a traditional monitor.


The term "big screen" is used to indicate a TV size larger than 40 inches in diagonal measurement. Until recently these are usually rear-projection screens Cheap Air Max 97 , although we are seeing more and more flat-panel displays at competitive prices.


The appeal of Rear-Projection TV (RPTV)

After all, what could be easier than getting a bigger TV? If you want a larger image with no muss and fuss, it can be purchased from any local big-screen retailer and delivered within a day or two.


Another the appeal of RPTVs is the impression created by big-screen retailers that RPTVs are cheaper than front projection systems.


Clearly there is a market for both types of home theater solutions. From a practical perspective your room size has a lot to do with determining which approach is best for you. If you don't have a large viewing room, a 40" to 60" diagonal TV will probably be plenty.

But if you want the large screen cinema experience and your room size will allow it, front projection is the way to go. Front projectors are made to produce screen images in the range of 70" to 120" diagonal or more. Once people realize they can get a picture up to four times the size for the same money as a good RPTV, it opens up a whole new world of entertainment possibilities.
