How can selecting the right projector screen save you money?



One with the biggest challenges when selecting an lcd projector is receiving the proper brightness for the area you will be using it in. For home use it is possible to normally darken the room. This means you'll be able to acquire a cheap lcd projector, usually saving quite a few hundreds, if not thousands, of dollars.



But generally darkening the area substantially is neither achievable nor desirable. Shopping for a larger specification projector will give you a brighter image, but it really is most likely less expensive to purchase a higher gain projector screen. The high-quality lcd projector may possibly expense you a thousand dollars a lot more than a dimmer model, while good quality projector screens that boost the image brightness and clarity are only several hundred dollars additional.



Projector Brightness and Screen Gain



The brightness of an lcd projector is offered in ansi lumens. Typical values for home theater and business presentation use are 500 to 3000. The greater the number, the brighter the picture are going to be. At the low end a darkened area is essential, while in the incredibly top rated end acceptable results are possible with greater light levels. The present generation of home use projectors are generally in the 1000-1500 range.



The get of a projector screen will be the boost in brightness in the image made compared to a flat matt white screen. This is provided as a uncomplicated number, eg 1, 1.5, 2 etc. A get of 1 suggests the image will be the same brightness as on a flat matt white surface, whereas 2 signifies the image is twice as bright.



As an example, for those who determine you may need about 1500 lumen to get an acceptable good quality picture, you might buy a projector with that rating and be concerned regarding the screen later. Or you could buy a less costly 1000 lumen model and match it to a projector screen using a gain of 1.5. This would provide you with an effective image brightness of 1500 lumen at a decreased expense.



Pretty High Obtain Projector Screens

Virtually all of the ambient light is absorbed or scattered, so the projected image seems pretty considerably brighter.



The Downside of High Projector Screen Acquire



While projector screen gain might assist you use a low cost lcd projector in brighter rooms than it could cope with on its personal, there are actually 3 trade-offs. These are the viewing angle, color shifting and uneven brightness.



High gain projector screens limit the viewing angle. For any screen with a get of 1 the picture seems high quality out to about 50 degrees from the projector. But at a acquire of 1.5 that viewing angle is reduced to about 35 degrees. More than 2 plus the viewing angle is down to about 25 degrees, producing it far more hard to layout your room.



Colour shifting happens as a consequence of the surface properties with the higher obtain screens. A true white screen will render colors accurately. By trying to manipulate the way light reflects, a higher obtain screen may cause a shift in some of the colors. That is seldom a cause to not obtain, unless you seriously do will need the colors to become spot on.



The most significant effect a high obtain projector screen has on image high quality may be the change is brightness in the center from the screen for the edge. There is usually as much as 30% difference at gains more than 2. This really is commonly not as well a lot of a problem, nevertheless it does turn out to be far more noticeable the higher the viewing angle.



Conclusion



A little bit study as well as a bit of leg work could assistance you make excellent savings. Treat the projector screen as an integral part of your system and invest in it together with your projector. Stop by stores and insist on demonstrations using a selection of lcd projector and screen combinations.



Deciding upon a very good high-quality, moderate obtain (1.4-1.6) projector screen can lower the cost and improve the efficiency of your system. A low-priced lcd projector can create a vibrant, clear image at higher than expected light levels. So whilst your projector screen may well expense extra, all round you save.
