A home theater projector is part of a home theater system that projects a very bright light and resizes the image to a larger one following the 16.9 widescreen ratio. It can project the image to a projection screen or a white wall. It can be used to envelope a whole wall or room with images for a home cinematic experience.
The first home theater projectors were huge, bulky, power consuming, and very expensive. Today’s home theater projectors, however, are designed to be slim, sleek, efficient, and affordable.
Kinds of Home Theater Projectors include the following:
LCD home theater projector
An LCD (Liquid Crystal Display) home theater projector works by passing bright light through an LCD chip and a lens to project images.
It is compact, light, portable, and very affordable.
However, it can project images with a “grid” effect, as the LCD chip is made up of small pixels.
If one of the pixels burns out, the whole LCD chip has to be replaced because it will leave a blank space on the image.
It also has a fixed resolution. Picture signals with a different resolution have to be scaled to fit the projector's resolution.
DLP home theater projector
A DLP home theater projector also uses an LCD chip to project images.
Each of the pixels contained in the LCD chip works as a reflective micromirror that tilt, reflecting light from a spinning color wheel to create images.
It has a very high resolution and a low power consumption.
It is a very compact device.
It also has the problem of having a fixed resolution and exhibiting the rainbow effect (the colors that appear on screen when the viewer looks at the screen rapidly from side to side).
Format: Choose a home theater projector that can display both a 4:3 standard format and a 16:9 widescreen format for more viewing options.
Brightness: Choose a home theater projector with a 1000 ANSI lumens for projecting in a dark room. Get one with a higher lumens rating if you want to project in a dimly-lit area.
