It is important to compare values for resolution, brightness and contrast ratio when buying a home theater projector in an online store in order to get the best deal possible.
Resolution is defined as the number of pixels that the projector produces. Thus, the higher the resolution is the sharper the image will be. Resolution is written in two numbers: the first one refers to the horizontal pixels while the second set of digits indicates the vertical pixels. Like for instance, 800 x 600 resolutions and 1024 x 768.
AMSI Lumens which stands for American National Standards Institute is the one responsible in measuring the brightness or light output of a projector and determines how well you see the projected images in a brightly lit room. The more number of lumens, the brighter and larger the image will be. If the projector does not meet the requirements of the computer being used, the projector will automatically compensate by making the picture a little bit smaller. Higher values of search lumens projectors are more applicable to be used in a well lit room.
In buying home theater projector, it is wise to choose those with higher contrast ratios in order to provide images with true high definition. Be sure that the projector will come with an adjustable lens in order to have an ultimate viewing pleasure.
A good projector size should generally be between five to seven pounds. The size this small enables the projector to be placed under the bed or in a carrying case.
Those are the basic things that need to be covered when buying for a home theater projector. Projector prices can range from $500 and $3000. However, there are several online stores, such as eBay, that offer projector at a discount rate of $500-$600. This will be more than enough to meet all of your requirements.
