DCB Adjustment
Dynamic Color Boost (DCB) is an advanced color adjustment technology. Through analyzing RGB signals, DCB
creates more vivid and natural images to suit various color environment needs. DCB has two types of color
enhancers: “Color Boost” and “Picture Boost” .
DCC: Dynamic color control
ICM: Intelligent color management
1) How to use Color Boost?
YCM adjustment: In addition to the basic R (red), G (green), B (blue) color adjustments, Color Boost has added Y
(yellow), B (blue), and M (magenta) for more color fine-tuning options. YCM adjustments are in the third icon labeled
22” LCD Color Monitor AOC 2116Sw
8
"Color Temperature "in the OSD menu. When adjusting YCM values, RBG values will also be changed automatically
due to the color correlation between RGB and YCM.
Five color-enhancement settings: To accommodate various display needs, Color Boost also offers 5 different
color enhancement modes: Full Enhance, Natural Skin, Green Field, Sky Blue, and Auto-Detect. Please go to the
fourth icon labeled “Color Boost” in the OSD menu and select one of the five settings you desire to be turned on.
Full Enhance: When "Full Enhance" is turned on, the color saturation of the entire screen is fully enriched, thus all
colors become more vibrant.

Nature Skin: When "Natural Skin" is turned on, the red and yellow colors are enriched automatically, thus presents
human skin with more natural and truer colors. "Natural Skin" setting is ideal for viewing human portrait and detailed
skin texture.
Green Field: When "Green Field" is turned on, the green color is enriched so that football field and mountain
landscape would look more natural and fresh. “Green Field” setting is ideal for watching mountain scenery and
outdoor sports.

10
Sky Blue: When"Sky Blue" is turned on, the color blue is being fine-tuned so that the sky or ocean landscape will
look more vivid and in-depth. "Sky Blue" setting is ideal for viewing sky and ocean images.
Auto Detect: When “Auto Detect” is turned on, every pigment will be detected and self-adjusted to render a lively
picture.
Demo: Screen divided into two for demonstration purposes.
2) How to use Picture Boost?
Users can change the color settings of a self-selected zone on the screen. The size and position of the selected zone
can also be adjusted. "Picture Boost" is located in the fifth icon labeled "Picture Boost" in the OSD menu. Turn on
"Bright Frame" to select a zone on the screen to be enhanced. Please note when adjust or turn on any one of the DCB
features, the rest of color settings including DCR will be disabled or return to default.

than the above illustrations.
DCR Adjustment
What is DCR?
Dynamic Contrast Ratio (DCR) auto adjusts the brightness of the screen so users can see the darker areas of the
displayed content in more depths. By increasing the darkness of the dark areas and the brightness of the bright areas,
contrast ratio is uplifted to exceed 2000:1. DCR value varies subject to the original CR values of the LCD module. The
higher the original CR, the higher DCR can be achieved. DCR is great for watching movie or video contents.
How to Use DCR?
Go to the first OSD icon labeled "Luminance", turn on or off DCR as desires. DCR boosts the contrasts between
lightness & darkness and enables the viewer to see more layers and details of the picture, especially in the darker
areas. Please note when DCR is on, DCB will be disabled.
DCR Demos:
