AV Lip Sync
The DreamScaler 4 automatically delays the input audio to match the video processing delay. You can choose to
increase or decrease the audio delay by changing this setting. Push the Up or Down button to display the current
additional bias delay setting (default 0). Use the Up or Down button to increase or decrease the delay in
milliseconds.
4.4 Input Picture Controls
Fine Detail
This control enhances the fine detail in pictures. Fine detail can be sharpened by adjusting the control into the
positive range, up to 100, it can be softened by adjusting this control into negative range down to -100. The
midrange setting is 0.
Edge Enhancement
This control enhances the sharpness of picture on the edges. To sharpen the edge change this setting into the
positive range up to 100, soften the edge setting a negative value up to -100. The midrange setting is 0.
Brightness
This control adjusts the brightness (black level) of the overall image output from the DreamScaler 4. If you turn it up
too high, it may make black look gray. In general, you should adjust this up until you see the black areas of your
display turn gray and then back it down just below that point. Default setting is 0 (midrange).
Contrast
Contrast adjusts the ratio between white and black signal levels and is effective as a gain control. The difference
between this and the Brightness control is that this adjusts the difference between the brightest and darkest part of
the image. Note that all displays have a maximum white level. Going beyond this level only “clips” the upper gray
levels and you will lose color resolution at the brighter levels. Adjust this control up until you see the brighter levels
of the image begin to wash out. At this point, back it down just below that point. The default setting is 0 (midrange).
Saturation
The DreamScaler 4 allows you to control the saturation of the image independent of the display. Saturation is the
same as the “Color” control on most TVs and controls the richness of the color in the image. The default setting is 0
(midrange).
Hue
As with Saturation, hue can also be controlled independent of the display. Hue is the same as the “Tint” control
found on most TVs and controls how colors are displayed in the image. The Hue control is not available for
Component or PAL/SECAM inputs. The default setting is 0 (midrange).
Y/C Delay
Sometimes there is a lag between the Luminance (Y) and the Chrominance (Pb/Pr or Cb/Cr) of the video signal.
This causes a color “smearing” because the color component of the image is not lining up properly to the black and
white luminance component of the image. The DreamScaler 4 can compensate for these errors in the source signal
by shifting the phase of the Y with respect to the C, forward or backward to align them properly.
Use the Down and Up buttons to adjust the phase and observe the effects on your display to obtain the optimal
setting. The default is 0.
Note:
The total audio delay cannot be less than zero, that is, the DreamScaler 4 cannot have negative audio delay. If you
choose to decrease the automatic delay setting by a certain amount, this value could be changed by the
DreamScaler 4 in situations where the DreamScaler 4’s calculated delay plus the specified additional delay results
in a value less than zero.
