First of all, do not assume you need a huge video screen in your media room. If your screen is too large, visual fatigue will detract from your cinema experience. A good, but general rule for screen size is to select a screen width that is half to one third the distance from the screen to the primary viewing location. You should keep the viewing cone, formed by a line going from your eyes to each side of the screen, to about thirty degrees.

You can use any display device and there are advantages and disadvantages to each type. DLP units tend to have better black levels than LCD units. LCOS units and variations have the tightest pixel structure.

Front Projection:

Advantages
A front projection set will produce the largest, most dynamic image. With a good projector and screen combination the image will be quite stunning, especially when watching native HDTV content. If you have never seen the picture produced by a good, front projection set up, you really should see one before you make any decisions.

Disadvantages:

Needs ambient light control. You need to control ambient light to get a really good picture because a front projection system cannot produce black. It must rely on the absence of light being reflected from the screen to show black or dark colors.

You have to have a physical projector mounted somewhere. This problem has improved tremendously in the last few years as CRT projectors have basically gone away and digital projectors have improved and shrunk to miniscule proportions.

Video projectors are noisy. They require cooling fans and these are loud. Some recent units however, are much quieter.

The larger picture and better detail reproduction will allow you to really see problems so you need to have quality video sources or the picture will suffer.

Many of the projectors on the market are either business presentation units or adapted from them. Business presentation projectors have much different requirements than home cinema system projectors. The most important requirement for business units is brightness. They sacrifice other performance parameters to achieve this. Home cinema projectors need extremely accurate color rendition, accurate grey scale tracking, deep blacks, and freedom from motion artifacts.
