If the display device is a poor quality LCD projector, the benefit may be minimal. Plasma displays also have different levels of quality! For example, the plasma displays being manufactured today have a much higher resolution and picture quality than those of just two years ago.

The Focus Enhancements QuadScan Pro can effectively improve the image quality of the newer plasma displays, but only if the source devices are of high quality (DVD/Sat/BETA SP, etc).

Tricks of Configuration

The Focus Enhancements QuadScan has two inputs that must be configured from the front panel of the QuadScan. These inputs can be independently configured for Composite, S-Video, or Component. As well, the QuadScan has a VGA throughput that must also be configured, whether it is used or not (on-terminated/terminated). This VGA throughput is not processed and cannot change the resolution of the input. In other words, it cannot scale a 640 X 480 (VGA) input into a 1024 X 768 (XGA) output.

Expected Performance

There are some basic rules you should apply to help determine the applications and expected performance of the Focus Enhancements QuadScan Pro:

1) Qualify the customers' needs and application/usage
2) Don't expect a poor quality video source to look like a XGA presentation with motion
3) If your customers expect too much, they may be disappointed
4) Use the best video source(s) available
5) Use the highest quality display device and screen you can
6) Read the included manual completely and setup the Quadscan step-by-step as instructed

Focus Enhancements QuadScan Pro is an excellent product when used in the application it was designed for, so be sure to qualify your customers' expectations and applications.
