Retractable Projector Screen FAQ - Get Answers Before You Buy a Projector Screen
A retractable projector screen is a good option for those looking to buy a projector screen as you can roll up into a metal casing when not in use. This allows for easier portability, and can keep the viewing area safe from harm. There are both pull-down and motorized projection screens, and in this article I will go into some of the commons questions asked by those purchasing a retractable projection screen.How can I save money on a retractable screen?Retractable manual screens are typically much cheaper than electric ones. While there are some exceptions, you will typically pay a large premium for electric screens. The effect of an electric screen rolling down in front of everyone can be exhilarating, but if your goal is getting a cheap projector screen look at a manual screen first.What is with the different material colors?The projector screen material typically comes in several different shades, and this is to accommodate different viewing angles, and ambient light situations. You will need to look at the manufacturers specifications for this, as different screen surfaces are used. A good all around color is matte white providing a large viewing angle, and a decent handling of ambient light.Do I need to have a tensioned screen?Some projection screens have a mechanism for tensioning with tabs on the side of the screen. What tensioning does is ensure the screen is completely flat which ensures a good picture. In most cases it is unnecessary to have a tab-tensioned screen, and a quality screen will have enough weight attached to the bottom of the screen to hang flat on its own.Does the black border make a difference?The black border enhances the quality of the image, and is especially important if you will be using the screen as a home theater projector screen. The reason for this is two-fold, the black border can absorbs excess light on the edges of the image making it less noticeable, and improves the perceived contrast of the image. This should be made of light absorbent fabric on all sides, not metal, to be most effective.What screen ratio should I choose?The ratio for a HDTV projection screen should be 16:9. For a normal definition projection the ratio is typically 4:3, but in some cases 1:1. This will have a large image on the viewing experience as large gaps of white above and below, or at the sides of the image will definitely detract from the viewing experience.
