Projection Screens Home Theater and Surface

The recent rise in popularity of home video projectors and large, clear images that can produce has led many newcomers to the realm of choosing home theater video projector as their display device of choice. Video projector images look best when projected onto a screen surface are adjusted correctly. While some eager new owners can start early by the objective their new projector on a white wall - they soon will want a projection screen for best results. Video projection screens come in many varieties - A simple Do-It-Yourself (DIY) home screen to the most elaborate, manufactured remote control electric models and various models in between. Video projector screens also come in a variety of surface finishes and reflectivity coefficients. All these factors must be considered when selecting a screen for your Home Theater.

Types Surface screen

Home Theater Projector screens come in a multitude of surface finishes. The variety of surface finish will have to depend on their projector model. Screen surfaces vary from matte white, some silver or gray-ish, models of reflective glass beads. Glass beads models increase the brightness of the image of efficiency similar to the way of a road sign reflects car headlights on your projector. Lumen-level (lumens = light output projectors) as models CRT benefit most from higher reflectivity (or gain) of the surface of a screen. Gain greater perceived surfaces increase the brightness of the projected image. Conversely - a brilliant projector is best viewed with dull white or a silver / gray surface. This is because the crystal balls in the higher gain screens have a tendency to "splatter" brighter light waves produced by a high light output projector. A silver / gray surface will also improve the perceived contrast level of LCD projectors not have the best contrast / black levels. So first decide the type and the light output of the projector you are buying and that will help determine the type of surface screen video projector that will be needed.

Model Types

Projection screens come in three basic styles - manual pull-down, fixed electric varieties. Manual pull down the models operate largely like a window shade. Electric models have a motorized mechanism to work for you and fixed screens are motionless and stay right where you place them. Fixed screens also provide the flattest of all areas of the screen. Pull-down and electronic displays may be susceptible to a slight waves on its surface. Although not mind if the proper care, some may prefer the absolute flat surface of a model fixed screen. The drawback to fixed screens is that you have to live with them in place while the retractable models can be implemented to display and then hidden from view until the next use.

Aspect Ratio

There is another very important factor to consider when buying a screen - the relationship of appearance of the screen. The aspect ratio of a projection screen refers to the shape of the available display surface. The screens come in two basic relations --- 4x3 aspect that is normal aspect ratio and 16x9 TV, which is the widescreen aspect ratio of standard or HDTV. The aspect ratio of the screen is an important decision before the purchase. That's because the fact that once you buy it there is no way to change the aspect ratio - which is not masking parts of the screen. You can mask the surface with material or curtains if you want to be creative and you can temporarily change the aspect ratio of the screen fixed.

You, of course, save much time and effort to fund research by the screen of your choice before purchase. Whatever your application and needs to be sure --- which is a projection screen surface and the model available to fit your particular situation.
