HORIZONTAL POSITION CONTROL
The location of the horizontal position control is shown in the Front Panel Connectors and
Controls Diagram on the previous page. Press and release the rocker button to shift the image by
one step to the left or right. Press and hold the button to shift the image continuously.
Note: The horizontal position control has no effect on the local computer monitor.
If the horizontal position adjustment is set to an extreme position on either the display device or
the CIA116, the output image may appear dark and / or the colors may be displayed improperly.
To position the video image and achieve optimum picture quality:
1. Set the display device's horizontal position control to the center of its adjustment range.
2. Adjust the horizontal position control on the CIA116 until the picture is centered properly
on the display device.
Note: The horizontal position control does not work with RGsB input signals.
SHARPNESS CONTROL
The CIA116 sharpness / peaking circuitry provides variable high frequency equalization that can
compensate for signal losses due to long output cable runs. Careful optimization of the sharpness
control at the time of installation will result in a greatly enhanced image with increased clarity and
edge detail. The amount of high frequency boost required for each display system will vary
depending on the length and bandwidth performance of the video output cables, and, to a lesser
extent, the resolution and frequency of the input signal. When using short output cables, the
sharpness control should usually be placed at the minimum setting to avoid over-peaking.
The sharpness control is located on the back of the interface (see diagram on page 7). Using the
IN9339 Adjustment Tool (provided), turn the sharpness control clockwise to increase the
sharpness setting, and counterclockwise to decrease the sharpness setting. The factory default
setting is minimum (no sharpness / peaking enhancement). The following guidelines are useful in
selecting the optimal sharpness / peaking setting:
If the image is soft and / or fine details in the picture lack clarity:
The sharpness is probably set too low. Increase the sharpness control setting.
If a white, ghosted image appears to the right side of the lines / characters:
The sharpness is probably set too high (over-peaked). Decrease the sharpness control
setting.
