Computer input
Video input
• Standard (for computer and video input)
This setting works with general.
• High contrast (for computer input)
This mode brightens mid-range areas making the overall image appear brighter.
The High-contrast Mode can reproduce low-range arias clearly even in brightly lit
environments.
• Cinema (for video input)
This mode boosts dark areas, improving the reproduction of dark pictures.
In effect, this improves the expressiveness of scenes with many dark areas,
common in movies, by preventing black saturation.
