Adjusting Levels For Analog Sources - Planar c50RP Quick Start Manual

Adjusting Levels for Analog Sources

This page applies to analog RGB (computer) pictures only. The
levels are best adjusted semi-automatically.
For analog RGB pictures, the levels for black and white vary from
one computer to another, or from one video processor to
another. They even vary between video outputs from a multi-
ple-output video card in a computer.
Your pictures will not look their best on the c50R/c67R until you
adjust for these differences. This is not about adjusting color or
contrast. It's about telling the c50R/c67R what the computer or
processor means by black and by white.

Do not go beyond the point where the minimum just goes to
zero. The idea is to just touch the zero level.
