Advanced Settings
VGA Setup:
This option is only availabe when connected to a VGA input; while connected, you can access
the following 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.
• 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 optimised.
TIP Adjust the Phase after adjusting Clock (see below).
For best results, use a good test pattern such as a smooth grey 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 stabilises and each pixel is clearly defined. You may notice that
you can stabilise 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 optimised.
USB Touch Mode:
Select the USB touch connector to connect a touch screen controller from one of the options:
Auto, USB Touch 1 (located at front panel), USB Touch 2 (located on I/O panel), PC.
