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 10000:1. 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.
