Some companies will spend thousands of pounds on the latest projector and then ruin the effect by showing the presentation on any old screen or even worse, projecting it onto a wall. The effect of this is to counter-act the benefits of buying a quality projector. With the latest in high-definition resolution technology and continual free fall in pricing, front projectors with a 100″ projection screen are the only way to watch football. Turn down the volume on your notebook and test the sound prior to beginning. Some sound-enabled projectors and auditorium sound systems have dedicated volume controls, so adjust those first.
Semi-specular high gain screen materials are suited to ceiling-mounted projector setups since the greatest intensity of light will be reflected downward toward the audience at an angle equal and opposite to the angle of incidence. However, for a viewer seated to one side of the audience the opposite side of the screen is much darkened for the same reason. Videophiles will look for the highest contrast ratios and will likely ignore the brightness specs on an LCD or plasma TV. Newer home theater projectors (1000 ANSI lumens or brighter) should also satisfy in any controlled lighting environment.
With the advances of contrast and lumen output technology, projectors are far more desirable than flat panel or rear projection displays. With the use of Digital Theater Paint you can get 4X the High Definition viewing pleasure for less than your average 42″ Plasma. Contrast 300:1 min. AE specs or the best you have is required.
The display adapter’s mother/control board controls that function along with maximum resolution, maximum refresh rate and the number of colors that can be sent to the monitor. Color CRT televisions use three electron beams and separate phosphors for red, green and blue. When you watch, you’re looking directly at the surface that the TV uses to create the picture. The grey color enhances color contrast and black levels in the projected image and also allows for more ambient light in the audience area than traditional surfaces. Available on all tab-tensioned and permanently tensioned screens.
The specific gray background color of the screen is chosen intentionally for the purpose of absorbing light. The newest Stewart screen for digital projectors is called a FireHawk and has a gray color, but also has a higher 1.3 gain as an alternative choice for digital projector applications. Other video projection screens can color shift, making projected images appear to push blue, green, or red. This push of color creates an unnatural balance to your projected image. Match the color codes on the cable to the input jacks (white to white, red to red) to maintain stereo integrity. If you need to send a mono signal, just plug into the left input only.
As the price of entry level home theater projectors drops below $1,000, the price of professional quality projection screens has become increasingly objectionable for new home theater enthusiasts. People who spend $1,000 for their video projectors do not want to spend another $500 to $1,500 for a screen.
For higher resolutions, such as SXGA (1,280 x 1,024), you’ll pay a higher price for the projector. With a street price under $700 this is a go-to model for anyone not requiring DVI or HDMI connectivity. It’s an incredible bargain given its features and quality.
