If you are looking for the perfect screen for your home theater then you need to know a few things. Most projectors come in one of two main types, retractable or fixed. A fixed screen is one that is stretched and mounted on the wall like a painting, it doesn’t movie. A retractable screen is able to be rolled up either manually or sometimes by a built in motor. You also need to consider how big you want your screen to be. Keep in mind of how big your projector can display images. You don’t want to try and make a projector display on a screen size that is not fitted for that model. Often it will result in blurred and poor images. A screen’s gain is another feature that you will want to look at. The gain is how much the brightness is reflected. For example, say you have a screen that has a 2.0 gain and a projector that has 1000 ANSI lumens. When you shine the projector onto the screen, the gain will multiply the brightness of the projector by 2, giving an overall brightness of 2000 ANSI lumens. A screen’s gain will also help you decide which projector you want because a high gain means you need less lumens for a bright picture, which will also help save money in the long run. Lastly the screen’s shape is another feature to consider. The screen’s shape depends on which aspect ratio you use. An aspect ratio is the ratio of pixels there are on the width and height of the image. A standard TV screen aspect ratio is 4:3, which means that there are 4 pixels on the width for every 3 pixels on the height of the screen. A widescreen display is usually a 16:9 aspect ratio. These are just a few of the many features to look for in the screen that works best for you.
