Home Cinema Projector

If you want the best home entertainment system, consider getting a home cinema projector. This is one way to experience cutting edge technology in your home with exceptional video viewing. You can find these projectors where they sell LCD and HDTVs and they cost about the same as a HDTV.

A home cinema projector projects a video signal as an image onto a projection screen using a lens system. It uses an extremely bright light to project the image. A modern home cinema projector will project the image while correcting curves, blurriness and other image disruptions.

When choosing a home cinema projector take into consideration how much space you have in the room you want to use it in. Next, you will want to pay attention to display resolutions. The most common for a portable projector includes SVGA (800×600 pixels), XGA (1024×768 pixels), 720p (1280×720 pixels), and 1080p (1920×1080 pixels). The more pixels the better the cinema effect it will have.

There are three types of home cinema projectors on the market. They are Cathode Ray Tube (CRT), Digital Light Processing (DLP) and Liquid Crystal Display (3LCD).
The CRT home cinema projector has the longest projection life. It can last up to 20,000 hours. However, it does take up a lot of room. A DLP home cinema projector can be used for movies and a LCD projector takes up less space.

A CRT home cinema projector uses cathode ray tubes that are usually green, blue and red. Maintenance on a CRT projector is practically non existent. Because it is so bulky, this type of projector is less popular.

Home cinema projectors that use DLP technology uses microfabricated light valves that are also called digital micro mirror devices (DMDs). The latest projectors work with higher speed and optimized color wheels and can display several primary colors at the same time. They are the smallest and use a single chip technology.

The 3 LCD splits 3 light sources into 3 beams of red, green and blue. Mirrors will then send the 3 colors to different locations in the projector box, then eventually through a prism and comes out as a single full color beam.

Consumers shopping for a home cinema projector should pay close attention to the brightness of the projector. It will need at least 1,000 ANSI lumens. However a rating of 1500 to 2500 lumens is most adequate for small screens that have controlled lighting or ambient lighting. 2500 to 4000 lumens is perfect for a medium-size screen with dimmed lighting. A very large screen requires over 4000 lumens if it is in a large room with no light control. The amount of light will not change as the size increases and as brightness decreases also. If the diagonal measure is increased, brightness is reduced.

The contrast ratio on the projector is important as well. A contrast ration of 2,000:1 or higher will provide the best color contrast for movies. A home projector will also need a screen for maximum benefit. The screen does not have to be large but it should be big enough for comfortable home movie viewing.

The LCD home cinema projector is the simplest system. It is the most affordable home cinema projector. When shopping for a home projector another point to consider is how many inputs it has and if you can connect your DVD player or your PC to your HD home cinema projector. The inputs should allow you to do that. It is important to have the device be compatible with your other equipment. Before you go out and buy your home cinema projector, make sure to look for the above points before you make your purchase.
