Advanced Settings
Auto Adjustment
Select Auto Adjustment from the Advanced Settings menu to force the display to reacquire and lock
to the input signal. This is useful when the signal quality is marginal.
Image Position (VGA sources)
Use the controls in the Image Position (VGA sources) Menu to fine-tune the image position.
• Left/Right: Select Left/Right from the Input Position menu to shift the projected image
horizontally. Press to shift the image to the right; press to shift it to the left.
• Up/Down: Select Up/Down from the Input Position menu to shift the projected image vertically.
Press to shift the image upward; press to shift it downward.
Phase (VGA sources)
This control adjusts the phase of the pixel sampling clock relative to the incoming signal. Adjust the
phase when an image still shows shimmer or “noise” after the Clock setting has been optimized.
For best results, use a good test pattern such as a smooth gray consisting of a clear pattern of black
and white pixels, or a similar “half on, half off” graphic image. Adjust the slidebar until the image
stabilizes and each pixel is clearly defined. You may notice that you can stabilize the image at more
than one point. Use either setting in such cases.
Clock (VGA sources)
This control sets the frequency of the pixel sampling clock, indicated by the number of incoming
pixels per line, so that all pixels generated by a particular source are sampled.
Steady flickering or several soft vertical stripes or bands across the entire image indicates poor pixel
tracking. Proper pixel tracking helps ensure that the image quality is consistent across the screen,
that aspect ratio is maintained and that pixel phase (see above) can be optimized.
