Page 7: Technical Highlights
TECHNICAL HIGHLIGHTS Picture Plus™ Technology – The VP251 is called a Line Doubler. However, just increasing the number of lines can make the image worse. This is where Picture Plus™ technology becomes critical. Picture Plus represents a complex, multi-stage process that takes advantage of all the patented Faroudja circuitry for color, motion and detail processing. - Page 8 Other more common the quality of its individual parts to its state-of-the-art sources however, such as VHS tapes (230 lines), are patented circuitry, the VP251 is truly in a class by itself. There is simply no finer video processor available.

10) Tint – This control adjusts the color phase seen as taining the separation of the luminance (picture) and the range from green to magenta. The VP251 has an chrominance (color) signal through the video signal APC (Automatic Phase Control) that maintains proper processing chain, thus avoiding rainbow patterns and phase. -
Page 11: Operating Instructions
When aligning the projector for the first time, the VP251 should be in the factory preset. Using 13) Factory – The Factory Presets are set to broadcast an external test pattern from a DVD, laserdisc or pattern industry standards. -
Page 12: Troubleshooting
The D15 output on the Faroudja processors output TTL sync. The best approach in these circumstances is to use a standard D15 to RGB breakout cable and connect it to the D15 connection on the Faroudja processor. Use the H & V sync from the breakout cable and the R, G, B from the BNC connectors on the rear panel for the best image. -
