Projector And Screen

The Center LCD projector, we focus a lot on the LCD projectors, so why am I writing about screens? Very simple, really. Buy your LCD projector in isolation from the screen without considering how they work together will probably cost more and give less than perfect results.

How to select the right screen save money?

One of the biggest challenges in the selection of an LCD projector brightness is suitable for the part you’ll use inches for private use, you can usually darken the room. This means you can buy a good LCD projector, often saving hundreds if not thousands of dollars.

But too often darken the room significantly is neither possible nor desirable. You buy a higher specification projector will give you a brighter image, but it’s probably cheaper to buy a high gain screen. The high quality LCD projector can cost a thousand dollars more than a dimmer model, whilst the quality of the screens that create the picture brightness and clarity, are only a few hundred dollars more.

To gain brightness of the projector and the screen

The brightness of the LCD projector is specified in ANSI lumens. Typical values ??for home theater and use the company’s presentation of 500 to 3000 The higher the number, the more the image. At the lower end of a darkened room is essential, while the highest acceptable results are possible with high light intensities. The current generation of domestic projectors are typically in the range of 1000-1500.

The profits of the projection screen is the increase in brightness of the image from a flat matte white screen produces. This is as a simple number, eg 1, 1.5, 2, etc. A gain of 1 means that the image of the same brightness as on a flat matte white and 2 means that the image is given two times brighter.

For example, if you decide that you need about 1500 lumen to get an acceptable image quality, you could buy a projector with this note and worry about the screen later. Or you could buy a cheaper 1000 lumen model and it corresponds to a screen with a gain of 1.5. This gives you an image brightness of 1500 lumens effectively reduced for a price.

Very High Gain Projection Screen

Typical cheap projector screens have gains of between 1 and 1.2. Profits from 1.5 to 1.8 are made with high quality finishes Pearlescent about twice as expensive. If money is no object and you need the maximum possible profit, then you need a color-screen projector.

Gains of up to 4 can now be done with projectors and screens. LCD projector emits only three wavelengths of light in the vicinity of red, green and blue. A corresponding projection surface is covered with a material that reflects only these wavelengths. Absorbs almost all ambient light or scattered so that the projected image will appear much brighter.

The disadvantage of high gain projector screen

While winning screen can help you, a good LCD projector in brighter, as it as his own, there are three arbitration. This is the viewing angle, discoloration and uneven brightness.

High-gain screens limit the viewing angle. For a screen with a gain of 1, the image of high quality is equivalent to about 50 degrees to the projector. But a gain of 1.5, as the viewing angle is reduced to about 35 degrees. More than 2 and the angle is about 25 degrees, making it much harder for the disposal of your room.

Color change occurs because the surface properties of higher gain screens. A true white screen, the colors accurately. Trying to identify ways to manipulate reflected light can, a high gain screen in a change in certain colors. This is rarely a good reason to not buy, if you really need are the correct colors.

The greatest impact of a high-gain screen image quality is the change in brightness at the center of the screen to the edge. It may take up to 30% difference with an increase of more than 2. This is usually not much of a problem, but it is much more noticeable the higher the viewing angle.

Completion

A little research and a little legwork you can help, big savings. They treat the canvas as part of your system and buy it with your projector. Visit stores and insist on demonstrations with a variety of combinations LCD projector and screen.

You can choose to win a good quality, moderate (01/04 to 01/06) increase the cost projection wall and reduce system performance. A good LCD projector can produce an image bright and clear in the light of the expected higher levels than. So while your screen may cost more, overall you save.
