Turning on auto adjustment
Auto adjustment forces the display panel to reacquire and to lock the input signal.
This can be useful if signal quality is marginal.
1. Press MENU > Advanced Settings on the remote control or keypad.
2. Select Auto Adjustment.
3. Use the arrows to select Yes.
Correcting the image position (VGA sources)
Use the controls in the Image Position (VGA source) menu to fine-tune the image position.
1. Press MENU on the remote control or keypad.
2. Select Advanced Settings > Image Position.
3. Do one of the following.
• Left/Right—To shift the image horizontally, press the arrow keys left or right.
• Up/Down—To shift the image vertically, press the arrow keys up or down.
Updating the clock (VGA sources)
The Clock 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 across the image can indicate poor pixel tracking.
Proper pixel tracking helps to ensure that the image quality is consistent across the screen, that the
aspect ratio is maintained and that the pixel phase can be optimized.
1. Press MENU on the remote control or keypad.
2. Select Advanced Settings > Clock.
3. Adjust the slidebar until the image stabilizes.
Adjusting the phase (VGA sources)
Christie recommends that you adjust the phase after you adjust the clock.
The Phase control adjusts the phase of the pixel sampling clock relative to the incoming signal. Adjust
the phase when an image continues to show shimmer or noise after the Clock settings are optimized.
For best results, use a test pattern that is smooth gray with a clear pattern of black and white pixels,
or a similar "half on, half off" graphic image.
1. Press MENU on the remote control or keypad.
2. Select Advanced Settings > Phase.
3. Adjust the slidebar until the image stabilizes and each pixel is clearly defined.
Changing VGA ADC settings
VGA ADC settings calibrate the analog-to-digital converter (ADC) for VGA sources on a display panel.
1. Press MENU on the remote control or keypad.
