Scheme:
Select Scheme from the Video Settings menu, then press
◄ or ► to select one of four image
quality presets (Vivid, Cinema, Game or Sport) depending on the type of program material you
are viewing. These presets automatically adjust the other image settings for optimal image

against a black background. The example above includes two vertical bars and four shaded boxes.

• The darkest black bars disappear into the background.
• The dark grey areas are barely visible.
• The lighter grey areas are clearly visible.
• The white areas are a comfortable level of true white.
• The image contains only black, grey and white (no colour).
