” and press
OK
to start to

6.8.2 Bias
To reduce noise of low gray scale images, LED display system normally will remove the low gray
scale part from input signals. But this will also bring information loss of images, especially dark
images like night scenes.
LVP615D
can adjust“ 8.2 Bias ” parameters to adjust. The value range is
：
0— 100. In the case
dark image information lost, adding this value will bring back the lost information and fully display
the image on LED display.
Note
: to make sure of full gray scale of output image, the default value is 50.
