In the LCD Projector Center we concentrate very a lot on LCD projectors, so why am I writing about projector screens? Rather basic seriously. Purchasing your lcd projector in isolation from the screen without the need of contemplating how they work collectively is probably to price you a lot more and give you less than ideal results.

How can choosing the ideal projector screen save you money?
One from the greatest challenges when choosing an lcd projector is finding the proper brightness for the area you are going to be using it in. For home use you'll be able to commonly darken the space. This means you may get a low-cost lcd projector, frequently saving several hundreds, if not thousands, of dollars.
But frequently darkening the area significantly is neither doable nor desirable. Getting a larger specification projector will give you a brighter image, but it is in all probability less expensive to get a higher get projector screen. The excellent lcd projector may possibly expense you a thousand dollars much more than a dimmer model, whilst high quality projector screens that improve the image brightness and clarity are only a handful of hundred dollars extra.
Projector Brightness and Screen Obtain
The brightness of an lcd projector is offered in ansi lumens. Common values for home theater and business presentation use are 500 to 3000. The larger the number, the brighter the picture might be. At the low end a darkened space is crucial, whilst at the really top rated end acceptable outcomes are doable with greater light levels. The existing generation of home use projectors are normally within the 1000-1500 range.
The get of a projector screen would be the boost in brightness of the image developed in comparison with a flat matt white screen. This can be provided as a simple number, eg 1, 1.5, 2 and so forth. A achieve of 1 implies the image will be the same brightness as on a flat matt white surface, whereas 2 suggests the image is twice as bright.
As an instance, in case you determine you will need about 1500 lumen to obtain an acceptable good quality picture, you can buy a projector with that rating and worry concerning the screen later. Or you could get a less expensive 1000 lumen model and match it to a projector screen having a achieve of 1.5. This would provide you with an effective image brightness of 1500 lumen at a reduced expense.
Incredibly High Achieve Projector Screens
Typical low-cost projector screens have gains of in between 1 and 1.2. Gains of 1.5 to 1.8 are achieved with high quality perlescent finishes at about double the cost. If money is no object and you have to have the maximum acquire feasible then you need a chromatically matched projector screen.
Gains of as much as 4 can now be achieved with matched projectors and screens. An lcd projector only transmits 3 narrow wavelengths of light in Red, Green and Blue. A matched projector screen is covered with material that reflects only these wavelengths. Almost all of the ambient light is absorbed or scattered, so the projected image seems extremely a lot brighter.
The Downside of High Projector Screen Achieve
While projector screen acquire may assist you use a inexpensive lcd projector in brighter rooms than it could cope with on its own, you will find 3 trade-offs. These are the viewing angle, color shifting and uneven brightness.
Higher acquire projector screens limit the viewing angle. For any screen having a obtain of 1 the picture appears high quality out to about 50 degrees in the projector. But at a gain of 1.5 that viewing angle is reduced to about 35 degrees. Over 2 and the viewing angle is down to around 25 degrees, creating it much more tough to layout your space.
Color shifting happens as a result of the surface properties of the greater achieve screens. A true white screen will render colors accurately. By wanting to manipulate the way light reflects, a high gain screen can cause a shift in some of the colors. This is hardly ever a purpose to not acquire, unless you genuinely do need the colors to be spot on.
The greatest impact a higher gain projector screen has on image good quality would be the transform is brightness from the center of your screen for the edge. There may be up to 30% difference at gains more than 2. This really is generally not also a lot of an issue, but it does grow to be far more noticeable the greater the viewing angle.
Conclusion
Just a little study in addition to a bit of leg work could aid you make great savings. Treat the projector screen as an integral part of your system and buy it collectively together with your projector. Take a look at shops and insist on demonstrations having a wide variety of lcd projector and screen combinations.
Picking out a great high quality, moderate obtain (1.4-1.6) projector screen can lower the cost and boost the overall performance of the system. A low-priced lcd projector can create a bright, clear image at larger than expected light levels. So whilst your projector screen may well expense extra, overall you save.
