Teaching big classes and business presentations nowadays have been made so much easier with dlp lcd projectors. There is no limit to what you can do with it. Unlike the overhead projectors we used in the years back, you can only present colored slides, and video presentations would not be possible.
These projectors allow you to show movies and clips, making your presentation clearer, more understandable and interesting. It is not even surprising that homes nowadays would have these projectors for their theater rooms—making family movie nights a lot more enjoyable!
There are some differences between the two projectors. A DLP would be more expensive than the LCD, but they could be used for longer hours. An LCD would be suitable for brightly lit rooms, more cost effective and is still the choice for most users because usually projectors are not used for hours anyway. But in the end it is the user who would determine which of the two projectors would be more useful to him, according to his needs.
