HD TVs seem to be grabbing all of the media attention these days, but projectors are not something you should forget about. A projector can offer a much larger screen than a traditional television, as well as other benefits. For instance, projectors provide a better gaming experience for the Nintendo Wii, as well as other consoles, like the Sony PlayStation and the Microsoft XBox. Projectors also have additional requirements, like a room with very controlled lighting. Projectors are not right for everyone, but they work great for some people. Let's take a look at some factors to consider when choosing a projector.
First off is resolution. Just like a traditional television, projectos can be found in a variety of resolutions, both standard and high definition. You can still purchase standard definition projectors which look acceptable, however generally you will want to go with a high-definition projector, just like you would with a television. This will offer a better picture, at least from sources where it is available.
Another big consideration with projectors is how big your screen will be. Projectors can easily and cheaply get much larger than traditional TVs; however you probably don't want to light up your whole wall. Calculate the screen size you will have and make sure to get a projector that can support a size that big.
A large part of what determines what projectors can go up to what size is brightness. This is measured in lumens. While that probably isn't a metric you are very familiar with, just know that more lumens means a brighter (and generally better) picture. Compare the lumens of different projectors to get an idea of which ones are better.
In addition to brightness, you want to pay attention to contrast ration. This is the ratio of white to black, and it greatly affects the perceived picture quality. Projectors with higher contrast rations will look much better, and can more accurately represent colour.
