Buying a video projection system requires the consideration of many factors such as image brightness, clarity, color quality, simplicity of operation, screen durability, rear screen vs. front screen projection, video and audio inputs and outputs, and of course price. Generally speaking, only the 2 or 3-tube type projection systems ($2,500-$3,500) are adequate for professional or large group use.
No doubt in the near future we will find the LED (light emitting diode) MATRIX video wall screens becoming popular and available. Then we will have achieved truly high quality large-screen video. These screens will emit video images with the brightness of a calculator or digital wrist watch instead of merely reflecting images as current video projectors do.
There are many low-cost TV projection systems now on the market, ranging in price from less than $1,000 for home TV kits to $300,000 for huge concert-hall systems. Before you buy, be sure personally to view in operation any projection system you might consider. If you can afford good equipment, video projectors can transform TV and video into a whole new dimension. It's like having a drive-in movie theatre in your own home. However, because the TV image is so enlarged, you will really notice the quality differences between videotape and film, and also the effect of good and bad lighting.
Experts predict that in several years, 1Q% of all new color TV systems being sold to consumers will be large-screen systems. Hopefully, the technical and creative content of the medium and the availability of low-cost videotape programming and hardware will improve sufficiently to make large-screen TV a worthwhile investment.
