How To Use a Projection Screen

People currently want a home theatre experience with less expense. This drift towards home amusement has increased demands for bigger, better resolution screens. This was once dominated by large screen televisions but the space it occupies has soured its future in newer consumers. Buyers want something that can provide better resolution, larger view, portable and almost weightless and that also saves space. The obvious solution is having a projection screen.

Projection screens are smaller movie theater screens that need a projector. This can create a small image from a video signal, which can be magnified into the projection screen. The bright beam of light and a lens system amplify the video image. There are a variety of models to choose from which could determine how you get to use them for entertainment purposes.

Images appear in the projection screen through the front or rear. You also need to determine which type of projector will work best for you:

  1. CRT. This model is similar to televisions that use cathode ray tubes to transmit pictures. They are for rear projection. They work well with portable screens.
  2. LCD. This version uses a lamp that conveys light through a tiny LCD chip that makes up the pixels to create an image. They are for front projection. They can be used for fixed projection screens mounted on walls or the pull-down screens that save space.
  3. DMD (Digital Micro mirror Device). This projector combines the previous technologies which makes it versatile for any type of projection mode.

Despite the technological awareness of many, very few people know how to use a projection screen. The following guidelines explain how. You'll need a projector, the necessary power cords, remote control and the projection screen.

  1. Attach the video player to the projector using their VGA cables. One end should come from the back of the projector while the other ends at the video player. Fasten securely.
  2. Plug the power cords of the projector and video player and turn it on. A red bulb lights usually when the power is on. Wait until the light turns green - which means that the projector is on and ready to transmit.
  3. Prepare the projection screen. This can be pulled down or fixed. Adjust the right viewing size. Turn on the speakers attached to the video player.
  4. Remove the lens cap of the projector. A blue screen will appear on the projection screen. Turn on the video player and wait until an image appears on the screen.
  5. You can use the projector's lens to fine tune the picture by using its zooming features. Use the remote control to adjust volume and you're all set.

Projector screens have come a long way from being used at business presentations to being an alternative for a home theatre experience worth the price. However, bigger is not always better for projection screens. Look for one that has a matte white color with a fine grain and heavy weight so that it projects a uniform video image.
