Show OSD can disable the On Screen Display. When using the front keypad for setup via the LCD, it will
prevent the OSD from coming on the screen. This is handy when making changes to the system while it is
being viewed.
Background Color determines the color of the window when no input signal is present.
Noise reduction
allows the DIDO LT to clean up an image with random noise caused by poor or weak
signal. There are two types of noise reduction filters available. The first one is “Spatial Filter” which is
good for signals from poor TV reception. The second one is “Temporal Filter” which is a good overall
noise reduction to clean up an image. There is a penalty when using noise reduction which is the
softening of the image. Best way to use noise reduction is trial and error to see what works best for the
application.
Motion handling is for DIDO LT Motion Adaptive De-interlacing. There are three options to choose
from. Option 2 gives the best overall compromise of feathering and jitter when enabling this feature.
Once again, it is best that different options are used with the content to see which works best.
Scaling Filter is for the graphics channel. This should be enabled in most cases especial when an image
is being down scaled or reduced in sized. The scaling filter is not used when an image is up scaled or
increased in size.
ADC Calibration
is for the RGBHV inputs color settings. The Auto will automatically adjust the gain
and offset for each color when a test pattern is inputted. The Manual allows adjustment to a user’s
reference or with external color analyzer.
