If you plan on using a video projector for professional or personal use, a projector can provide many benefits. Depending on what you intend to use the projector for, there are certain things you should look for before making a purchasing decision.

What relationship Aspect Do you want the projector to the screen? The two main types of aspect ratios is 4:3 (standard) or 16:9 (widescreen and high definition televisions). Most people now are choosing projectors in 16:9 format for their home theaters, while some prefer the 4:3 format, as many films created before 1953 are in that format.

Do you plan to take the spotlight with you? If you want a projector that is easy to take around one room to another or from one office to another, consider the size and weight of the unit. The lighter and smaller the projector, will be portable.

Are you worried about the contrast color in the image? If you want a good contrast in color, as the blackest blacks and whitest whites, and then look at the relationship contrast of a particular projector. The contrast ratios range is anywhere between 500:1 and 5000:1, and more. The higher the contrast ratio, the greater the amount of colors available.
