Terminology

Definition

Gain Unit of measure depicting a projection screen's actual brightness.  The industry standard testing control measuring at pure "white" is magnesium carbonate at 1.0 gain.  Gain measurements less than 1.0 are called "sub gain" while measurements over are called "high gain".
Grayscale The level of gray that becomes more apparent as the color saturation decreases.  With 0% color saturation, the only visible shades are the dynamic range between "white" full neutral light) and black (the lack of light).
HDTV Acronym for "High Definition TeleVision" the most common broadcast television aspect ratio measuring 16:9 or 1.78:1. (see aspect ratio)
Herz (Hz) Measure of frequency in cycles per second. This is the standard measurement in audio, visual, and electrical signals.
High Gain A material that measures with a brightness that is 1.1 gain or higher. (see gain)
Horizontal Resolution The full number of vertical lines individually crossing the horizontal rows of a projected image. This is measured in pixels and is often used in defining aspect ratios such as in HDTV, 1920 × 1080 indicates the ratio of 1920 pixels of horizontal resolution to 1080 pixels of vertical resolution.
Hz Measure of frequency in cycles per second. This is the standard measurement in audio, visual, and electrical signals.
Invert Image Projector setting that allows the image to invert should the projector be ceiling-installed.
ISF Acronym for Imaging Science Foundation.  A world renowned organization that measures and identifies the ranges and optimal settings of Dynamic Range, Color Saturation, Color Accuracy, and Resolution.
