channel is temporarily created based on factory-defined defaults for this signal. The
channel number assigned to this channel is the lowest available number from 01-99.
NOTES: 1) An automatic channel will be discarded unless one or more of its
parameters are changed, and will not appear in the Channel List (see below). 2) If
two channels have the same distinguishing source characteristics except for the
reversal of sync connectors (i.e., H-sync and V-sync, are switched), they are still
defined as distinct channels. 3) You cannot define a new channel without a signal
present.
If the incoming signal does match an existing channel, the image will be set up and
displayed as usual according to the parameters currently defined for that channel.
USING A CHANNEL: You can normally select a channel at any time by pressing Chan
(see right). If you want to prevent a channel from appearing in this list, you must edit
the channel as described
in Channel Edit later in
this section. Such a
channel can still be
selected as shown at right.
NOTES: 1) The current
channel is highlighted
upon entering the
Channel List, or, if this
channel is not displayed in the list, the first channel in the list is highlighted. 2)
Channels created automatically do not appear in the Channel List unless a
parameter has been changed.
All available channels are listed in the Channel Setup menu, which describes how
each channel can be accessed and which serves as the gateway for editing, copying
and deleting channels.
From the presentation
level press 
Menu to
display the Main menu.
To display the Channel
Setup menu, press 
, or
move the highlight to the
Channel Setup option and
press 
Enter. The Channel
Setup menu will appear
(see sample at right),
with the active channel
highlighted.
WHAT APPEARS IN THE CHANNEL SETUP MENU? As shown in Figure 3.10, this menu
lists all channels defined so far and indicates how they are connected to the projector.
The far left column contains current channel numbers defined. The values in the far
right columns indicate horizontal and vertical frequencies—if a name has been
defined for this channel, it appears here instead. Other columns contain details
pertaining to each channel setup, such as its switcher number, slot location, a variety
of icons indicating access to the channel, and an abbreviated description of each
signal type. See Editing a Channel Setup for details.

SIGNAL TYPE — Either channel list, whether the Chan key list or the Channel Setup
menu, identifies signal types in a shortened form as defined below. These descriptors
indicate what signal information the projector used to identify a match for a given
channel, and are preceded by either an “i” (interlaced signal) or “p” (progressive
signal). See Table 3.1.

If desired, edit the following channel setups in the Channel Edit menu:
• 
CHANNEL NAME: An alpha-numeric label can be defined and/or changed
here. Channel names can be up to 12 characters in length.
• 
CHANNEL NUMBER: A channel number from 01 to 99 can be changed
here. NOTE: If you enter a channel number that already exists, a dialog
message appears indicating that this number is already in use–assign a
different channel number.
• 
SWITCHER NUMBER: “0” represents the projector itself. Or, if the input
source is connected to a switcher, the default will be the lowest switcher
number available (from 1-9)–change here as desired.
• 
SLOT: 1 (Input1), 2 (Input2), 3 (Input3), or 4 (Input4) for projector inputs, or
current slot number (1-9) if the source is connected to a switcher.
• 
LOCKED: If checked, all of the image settings for this channel are disabled.
If unchecked (default), all available image settings can be adjusted as
desired. You cannot use Auto Setup with a locked channel.
• 
IN MENU: If checked (default, except for automatically defined channels
with unchanged parameters), this defined channel will then appear in the
list available when 
Chan key is pressed. If unchecked, the channel must be
accessed via 
Chan on the keypad or via the Auto Source function. NOTE:
On-screen display of the channel list is an option that must be set in the
Menu Preferences menu.
• 
AUTO SOURCE: If checked, (default), the projector can automatically
locate this channel when an incoming input signal matches. If not
checked, the projector can locate the selected channel only when it is
directly selected via 
Chan on the keypad—and a change in input signal will
not result in a channel change.
• 
PREVIOUS CHANNEL: Select this option to see or change Channel Edit
settings for the previous channel in the Channel Setup list.
•

Most options for source-specific image adjustments can be accessed through two
menus: Size and Position (
Menu ) and Image Settings (Menu ), both of which are
listed in the Main menu. While in either of these two menus, you can change settings
affecting the image from the current channel by working with the appropriate
slidebars, checkboxes and pull-down lists. 
Exi t will always return to the previous
menu (or to the presentation, if from the Main menu) and accept any changes you
may have made. Or you may prefer to begin with an automated setup in which the
projector quickly defines certain parameters for you—select Auto Setup from the
Main menu. These settings can then be fine-tuned in Size and Position and Image
Settings at any time.
From your presentation, access any of the individual options in these menus by
pressing 
Menu followed by the appropriate two-digit number representing their
location in the menu system. For example, press Menu   to quickly access the
“Color Setup” option in the Image Settings menu.
For certain options, you may prefer to use a “direct key” from presentation level to
go directly to a particular option rather than traveling through the menu system at all
(note: this is not available for all display parameters). For example, press 
Cont to
access the “contrast” slidebar immediately. Press 
Exi t to return to your presentation.
NOTE: 1) To hide the “direct” slidebars only, make sure the Display Slidebars
option in the Menu Preferences menu is unchecked.  2) To hide the entire menu
system from view, toggle the on-screen display OFF: press and hold the 
OSD* key.
If you want the projector to quickly set up the image for you, select “Auto Setup”
from the Main menu. A confirmation box will ask if you really want to continue, in
which case display parameters listed in the Table below will be set for you. An “Auto
Setup” can save time in setting up an image, and you can also make further
adjustments as desired. You must have an unlocked channel present to use Auto Setup.

The two-page Size and Position menu
allows you to increase or decrease the size
of your image, change its proportion
(aspect ratio), move the image to a specific
area of the screen, and refine other related
parameters. Use Size and Position controls
to match the image precisely to the screen
size and aspect ratio needed for your
application.
Refer to Using Slidebars and Other
Controls (earlier in this section) if you
need help using any of the following
slidebars or pull-down lists to alter your
image. Changes made to the Size and
Position menu are applied immediately
and are saved when you exit the menu
(press 
Exi t or Menu).
Resize Presets
Use Resize Presets to quickly
display an image in its native
resolution (including
anamorphic) or to
automatically resize an image
to closely fit the screen. The
value for Size, Position and
Blanking parameters
(described later) will, in turn,
change as necessary without
your having to set them
manually. Resizing options
for non-tiled applications are explained in detail below.
WHAT IS THE PROJECTOR’S DEFAULT? When displaying a new source, by default
your image will fill the screen as fully as possible for the type of source present. See
Select “Default” below.
WHEN “CUSTOM” APPEARS: The “Custom” descriptor automatically appears in the
Size and Position menu when any of the values for Size, Vertical Stretch, H-Position,
V-Position or any Blanking do not correspond to those for a preset. It is not an option
in the Resize Presets pull-down list.
• Select 
“DEFAULT” (default) for most images. This option will center and display
your image as large as possible for the present source as described below:
9 A graphic image will resize to fill the screen, regardless of its original
aspect ratio. For example, 1024 x 768 becomes 1280 x 1024 in “S” models.  Ima

Figure 3.15. Resize Presets Choices 
						

							OPERATION

Roadster/Vista User’s Manual
9 A video image will resize to fill the screen while still maintaining its
aspect ratio (assumed to be 5:4).
9 An HDTV wide-screen (16:9) image will resize to fill the screen
horizontally while maintaining its 16:9 aspect ratio—i.e., there will be
black borders at top and bottom, commonly called “letterboxed”.
9 A non-HDTV anamorphic (16:9) image, typical of DVDs, will be
stretched vertically.
So with the exception of HDTV (16:9), the “Default” setting produces an aspect
ratio that is either almost or exactly 5:4 (if “S” model) or 4:3 (if “X” model). See
examples below.
NOTE: Shown with “S” model resolution (1280 x 1024). “X” models are 1024 x 768.
• Select “NO RESIZING” to display the image in its native resolution, which may be
smaller or larger than the native resolution of the projector. All Size, Vertical
Stretch, H-Position, V-Position or Blanking values will change accordingly. For
example, for a source with a native resolution of 800 x 600, “No Resizing” will
center a small image within a black border. Conversely, an HDTV image is wider
than both 1024 and 1280 and will be cropped on the sides—or, in the case of
“1080i” HDTV, cropped at top and bottom too. With “No Resizing”, signals with
non-square pixels, such as video connected to 
INPUT 3 or INPUT 4, produce
distorted images that are too tall or too wide. See below.
• Select “FULL SCREEN”  to use all pixels (1024 x 768
in“X” models, 1280 x 1024 in “S” models) for
displaying the image, regardless of source or original
aspect ratio. See right. NOTE: SXGA resolution shown.
• Select 
“FULL WIDTH” to fill the display from left-to-
right. Depending on the source, this may create top
and bottom borders. 
						

							OPERATION
Roadster/Vista User’s Manual3-27
• Select “FULL HEIGHT” to fill the display from top-to-
bottom. Depending on the source, this may create
side borders.
• Select 
“ANAMORPHIC” to display an entire non-
HDTV “wide screen” (anamorphic) image in its native
16:9 aspect ratio. Known as letterbox, the image will fill
the screen from left-to-right, but will not use all vertical
pixels available (top and bottom will be black). If you
do not choose “Anamorphic” when a non-HDTV
anamorphic image is present, the default image will be
stretched vertically, characterized by obvious distortion
and “thin people”.
NOTE: 1) SXGA resolution shown. 2)Use “Anamorphic” for regaining a 16:9
display of non-HDTV anamorphic sources only (typically found on some DVDs,
for example). For HDTV, the “Default” setting will produce the same result.
• All 
TILED resizing choices are selectable only if you have defined a tiled group of
projectors in the Tiling Setup submenu. See 3.10, Using Multiple Projectors.
Size
Size controls both the image width and height in tandem, maintaining the original
aspect ratio (proportion) of data from the incoming signal. Under some conditions in
“X” models, adjusting Size also adjusts Keystone.
NOTE: If Size 
$1000 (1000 = No Resizing) and Size x Vertical Stretch value
$1,000,000, adjusting Size also adjusts keystone simultaneously. Requires “X”
model.
Vertical Stretch
Vertical stretch adjusts the height the image while keeping the width constant. Use
Vertical Stretch to display data from the incoming signal in a different aspect ratio.
Under some conditions in “X” models, adjusting Vertical Stretch also adjusts
Keystone.
NOTE: If Size 
$1000 (1000 = No Resizing) and Size x Vertical Stretch value
$1,000,000, adjusting Vertical Stretch also adjusts keystone simultaneously.
Requires “X” model.
Pixel Track
(
SHORT CUT: Press Pixel and adjust the top slidebar.)
Pixel tracking adjusts the frequency of the pixel sampling clock, indicated by the number
of pixels per line, so that all pixels generated by a particular source are sampled. Proper
pixel tracking ensures that the image quality–whether good or poor– is consistent across
the screen, that aspect ratio is correct, and that pixel phase can be optimized (below). 
						

							OPERATION
3-28
Roadster/Vista User’s Manual
NOTE: By default, the projector will sample at the correct frequency for most sources.
Pixel tracking is adjusted most effectively using a good test pattern, such as a smooth
gray consisting of a clear pattern of tiny black and white dots, or a similar “half on,
half off” graphic image, such as the Windows shutdown screen. Steady flickering or
several soft vertical stripes or bands across the entire image indicates poor pixel
tracking. Adjust the slidebar until the stripes broaden to the point where one large
stripe fills the image. Again, the image may still exhibit some noise. See Pixel Phase.
Pixel Phase
(
SHORT CUT: Press Pixel and adjust the bottom slidebar.)
Pixel phase adjusts the phase of the pixel sampling clock relative to the incoming
signal. It is used primarily for adjusting RGB inputs.
NOTE: Adjust pixel phase after pixel tracking is properly set.
Adjust pixel phase when the image (usually from an RGB source) shows shimmer or
“noise”. Pixel phase adjustment is done most effectively from within a proper test
pattern, such as a smooth gray consisting of a clear pattern of tiny black and white
dots, or a similar graphic image, such as the Windows shutdown screen. Adjust until
the image is stable and each dot is clearly defined. Using the numbers on the slidebar
as a guide, you will notice that you can actually 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 select either setting.
Filter
Filter applies a low pass filter to the input signal. This removes high frequencies
which can improve pixel phase noise but which also reduces signal bandwidth. Note
that most signals will not require any filter adjustment—use the filter option only if
standard pixel tracking and phase adjustments do not adequately clear up a “noisy”
signal. For best results:
1. Optimize Pixel Tracking and jot down the
value.
2. Optimize Pixel Phase
3. If the image is still too noisy, return to Pixel
Tracking and “mis-adjust” so that 2 vertical
bands of noise appear, separated by a good
center band. See right.
4. Adjust Filter to maximize the width of the good
area. See right.
5. Return Pixel Tracking to its correct setting from
Step 1.
6. Readjust Phase.
NOTE: “Filter” affects only the current signal.
H-Position
(
SHORT CUT: Press Pos it ion and adjust the top slidebar.)
This option moves image right or left. 
						

							OPERATION
Roadster/Vista User’s Manual3-29
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
(
SHORT CUT: Press Pos it ion and adjust the bottom slidebar.)
This option moves the image up or down.
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.
Lens Control 
(STANDARD IN ROADSTER ONLY)
(SHORT CUT: Press Lens to activate the Lens Control submenu.)
For a full description of the Lens Control submenu, see 3.3, Using the Keypad (
Lens
key) and 2.8, Zoom, Focus and Lens Offset.
Blank: Top, Bottom, Left or Right
These slidebars blank (turn to black) the top, bottom,
left, or right edge of the image so that any unwanted
information is cropped from view. For example, when
displaying native size video you may want to blank
out a few of the top lines. Do not use in combination
with Keystone control.
PLL Loop Gain
This control changes the relative offset to the default gain. The default PLL (Phase
Lock Loop) Loop Gain setting of 10 is set automatically with a Pixel Tracking
adjustment and is correct in most cases. In rare instances, such as if your image
exhibits tearing or “flag-waving”, increase the PLL loop gain setting as necessary.
Or, if your image is unstable and “breaks up”, this may indicate that the PLL loop
gain setting is either too high or too low. PLL Loop Gain affects the current channel
only.
Keystone
NOTE: This function is not available in “S” models.
Adjust the keystone control if images appears non-rectangular or keystoned in shape—that
is, smaller at either the top or bottom edge. The effect of keystone adjustment is similar to
physically tilting the projector forward or backward in relation to the screen, and it affects
all sources.
NOTES:  1) Keystone is enabled for a source only if  Size is 
$1000 and Size x
Vertical Stretch is $1,000,000. 2) Keystone adjustment is not available in “S”
models. 3) Avoid using Keystone with Blanking.
