- When you decide to buy a projector screen, you should know the different types that are available. The most common ones are the collapsible, the tripod, and the fast folding. If you would like one that is durable and portable, you can opt for the tripod. Fast folding screens are portable too, but the only thing is that they require a lot of time to set up.
- It is important to know about the surface of the screen too. Basically, matte gray and white are the two most common types of screens. The matte gray surface reflects more light and has a wide viewing angle. It also offers better contrast, which is very useful when used with a projector that produces a lot of brightness.
- When selecting a screen, remember to check out the sizes available. There are some designs that only measure 40 inches diagonally from one corner to another, and there are screens that measure up to 15 feet.
You can determine the size after taking into consideration the seating arrangements of the room, and the distance the projector needs to be from the screen. This needs to be done because the projector will require enough brightness to generate a quality image on the screen.
- You will also be required to know the aspect ratio. The choice of aspect ratio is either 4:3 or 16:9. The most popular is a screen with the aspect ratio of 16:9; however, standard aspect ratio used by TV and video is 4.3.
This was some information on buying a projector screen. These are used in offices, parties, and social gatherings. So, if you are planning to buy one, rest assured that you are making a smart investment.
