OPERATION
Pixel Track
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 can be optimized (described below). Tracking determines 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.
NOTE: By default, the projector samples at the correct frequency for most sources.
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, such
as the Windows shutdown screen. Adjust the slidebar until the vertical stripes broaden
to the point where one large stripe fills the image. If the image still exhibits some
shimmer or noise, adjust Pixel Phase (below).
Pixel Phase
NOTE: Adjust Pixel Phase after Pixel Tracking.
Adjust pixel phase when the image (usually from an RGB source) still shows
shimmer or "noise" after pixel tracking is optimized. Pixel phase adjusts the phase of
the pixel sampling clock relative to the incoming signal.
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, such
as the Windows shutdown screen. 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—i.e., you may find that the image appearance at "11" is identical to
the image appearance at "38", thus you can use either setting.
If some shimmer from a video or HDTV source persists, use the "Filter" control to
remove high-frequency noise from the signal.
H-Position
This option moves the image right or left within the area of available pixels.
NOTE: The value shown represents where the approximate center of the image lies in
relation to the total number of pixels available horizontally. This varies widely
according to the signal—watch the image while adjusting.
V-Position
This option moves the image up or down within the area of available pixels.
NOTE: The value shown represents where the approximate center of the image lies in
relation to the total number of pixels available vertically. This varies widely
according to the signal—watch the image while adjusting.
Swap PIP Images
(
SHORT CUT:
Press
on the standard Roadie 25K remote.)
Swap
Toggle the current picture-in-picture relationship so that the primary image becomes
secondary, and the secondary image becomes primary. Swapping is available only
when PIP is enabled. Note: Not available in v1.0 software. Shown as "Reserved".
