There is a method to bring the movie theatre experience into the living room and that's through the use of a 1080p video projector. A 1080p projector acts much like the projectors at movie theaters solely they project a video clip signal, rather than employing a film reel. Setting the projector from the right room, giving it enough space on the wall to project, you can bring the particular movie theater experience to your home.
A 1080p projector uses a bright light to task an image onto the wall or screen. It also allows for any user to adjust virtually any blurriness or other challenges that can affect the caliber of the picture. Other than using them for personal use in your own home, a 1080p projector is usually connected to a laptop or computer for presentations either at school or work. There are plenty of different types of projectors obtainable, each designed with various features and fitting towards any budget. There are four common displays for projectors that each have a different quality: SVGA(800x600), XGA(800x600), 720p(1280x720), as well as 1080p(1920x1080).
Finally there are LED projectors that do not require their lamp to be replaced with the LED's powering it. Any projector that offers 1080p resolution offers the most effective resolution of video projectors that are available. The other thing to keep in mind when comparing projectors is also the brightness that they offer. The price of a projector depends more within the brightness of the projector instead of resolution offered. Brightness is definitely rated by ANSI lumens, with the higher the number this brighter the projector. An excellent combination is to have a high ANSI rating having a resolution of 1080p. By finding the highest mix off the two (mixed with the lowest price) you can find a projector that displays a lovely picture in any situation who's is used.

It would take a book to answer all your questions.
See the sites at the links for most of what you need to know.
Every projector is a bit different. You must start with your needs/preferences in mind. Costs vary form a few $hundred to many $thousand ... although a reasonable image can be had on a $600+ projector.
Higher resolution (e.g. 720p, 1080p) is better, but costs more. VGA and XGA, etc are business projector resolution designations. If you want for home theater use you want to get 720p or 1080p.
Contrast ratio is king ... get at least 2000:1 ... but more is better (BUT, see 2nd link). Other key considerations include colour accuracy, video processing quality, inputs, fan noise, basic technology (DLP, LCD or LCoS). See 1st link for input.
Projectors can be left on, but lamps wear out (~3000 hrs of life) and cost a lot ($300+) to replace (See 3rd link for how to protect lamps)
There are many good brands ... see reviews at the first link.
A projector is by far the best way to get a BIG picture (90"+), but lamps need to be replaced, the room should be dark (or at least dim), and you need a screen (can cost $thousands, but you can make your own for $100 ... see 4th link).
The screen size needs to be matched to the room dimensions/viewing distance (See last link).
There ... a course in a few paragraphs .... now go and do the reading before even thinking about buying. Good Luck!
