Copying or Deleting Channels 
TO COPY A CHANNEL, highlight the desired channel in the Channel Setupmenu, then press
to go to the Channel Copy/Deletesubmenu. Select Copy and press         -a new channel
will be created. It is identical to original, which still remains, but it is identified with the next
available number from 01-99. If you change your mind and do notwant to copy the current
channel, press         to cancel and return to the previous menu. Copying channels is a quick
method for creating numerous channels, each of which can then be edited and adjusted for a
variety of presentations in the future.

TO DELETE A CHANNEL, highlight the desired channel in the Channel Setupmenu, then
press          to activate the Channel Copy/Deletesubmenu. Select Delete and press        -a
confirmation window will appear to make sure that you really want to delete this channel.
Figure 3.9. Deleting a Channel
TO DELETE MULTIPLE CHANNELS, highlight any channel in the Channel Setupmenu
and press          to go to the Channel Copy/Deletesubmenu. Select Delete Unlocked Only and
press         to delete all unlocked channels. Or select Delete All Channels to delete all chan-
nels, even those that are locked. In either case, the current channel will remain but will be rede-
fined from projector defaults. 
NOTE: For any deletion, a confirmation box appears to make sure that you really want to
delete. Select Cancel (default) if you dont want to delete after all.
Editing a Channel Setup
The basic setups that describe how and where a channel can be accessed are listed in the
Channel Setupmenu. These channel setups can be edited at any time in the Channel Editsub-
menu.

CHANNEL EDIT - STEP 3
If desired, edit the following channel setups in the Channel Editmenu:
z CHANNEL NAME: An alpha-numeric label can be defined and/or changed here. Channel names
can be up to 12 characters in length.
z 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. 
z SWITCHER NUMBER: 0 represents the projector itself. This will likely always be the case for
the VX-5c.
z SLOT: 1 (       ), 2 (        ), 3 (        ) , or 4 (         ) for projector inputs.
z 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.
zIN MENU: If checked (default, except for automatically defined channels with unchanged parame-
ters), this defined channel will then appear in the list available when   key is pressed. If unchecked, the
channel must be accessed via         on the keypad or via the Auto Source function. NOTE: On-screen dis-
play of the channel list is an option that must be set in the Preferences menu.
z 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   on the keypad-and a change in input signal will not result in a channel change.
z PREVIOUS CHANNEL: Select this option to see or change Channel Editsettings for the previous
channel in the Channel Setuplist.

3.6 Adjusting the Image
Most options for image adjustments can be accessed through two menus: Size and Position
(                   ) and Image Settings(              ), both of which are listed in the Mainmenu.
While in either of these two menus, you can change settings affecting the image from the cur-
rent channel by working with the appropriate slidebars, checkboxes and pull-down lists.
will always return to the previous menu (or to the presentation, if from the Mainmenu) and
accept any changes you may have made.
From your presentation, you can access any of the individual options in these menus by press-
ing         followed by the appropriate two-digit number representing their location in the menu
system. For example, press                       to quickly access the color temp option in the
Image Settings menu.
Note that 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          to access the contrast
slidebar immediately. Press          to return to your presentation.
NOTE: 1) To hide the direct slidebars only, make sure the Display Slidebars option in the
Preferencesmenu is unchecked.  2) To hide the entire menu system from view, toggle the on-
screen display OFF: press and hold the          key.
Auto Setup
If you want the projector to quickly set up the image for you, select Auto Setup from the
Mainmenu. 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 set-
ting up an image, and you can also make further adjustments as desired.
Image Size and Position
The 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.

Resize Presets 
Use Resize Presetsto quickly display an
image in its native resolution (including
anamorphic) or to automatically resize an
image to fill the screen. The value for Size,
Positionand Blankingparameters (described
below) will, in turn, change as necessary
without your having to set them manually.
z DEFAULT SETTING: When displaying a new source, the default “Full Screen”
option is in effect, meaning that your image will fill the screen as fully as possible for
the type of source present:
* A graphic imagewill resize to fill the screen, regardless of its original aspect
ratio.
* A video imagewill resize to fill the screen as closely as possible while still
maintaining its aspect ratio. Since a video image is not precisely 4:3, there will
likely be a handful of unused “border” pixels.
* An HDTV wide-screen (16:9) imagewill resize to fill the screen horizontally
in a 16:9 aspect ratio (i.e., with top and bottom borders).
zWHEN “CUSTOM” APPEARS: The “Custom” descriptor appears in the automati-
cally when any of the values for Size, Vertical Stretch, H-Position, V-Positionor
Blankingdo not correspond to those for a preset. It should not appear as an option in
your Resize Presetspull-down list.
zSELECT “NO RESIZING”to display the image in its native resolution, which may
be small or larger than 1280 x 1024. All Size, Vertical Stretch, H-Position, V-Positionor
Blankingvalues will change accordingly. For example, for a source with a native resolu-
tion of 800 x 600, “No Resizing” will center a small image within a black border.
Conversely, an HDTV image is wider than 1280 and will be cropped on the sides or, in
the case of “1080i” HDTV, cropped at top and bottom too.
zSELECT “FULL SCREEN” (default) to center and display your image as large as
possible for the present source. Note that video and HDTV both maintain their original
aspect ratios (i.e., there will be at least a few unused pixels), other sources change their
aspect ratios as necessary

OPERATION
order to fill the screen. Non-HDTV (16:9) anamorphic images, common on DVDs, will be
stretched vertically. With the exception of HDTV (16:9), the “Full Screen” setting produces an
aspect ratio that is either almost or exactly 4:3.
zSELECT “ANAMORPHIC”to display an entire
non-HDTV “wide screen” (anamorphic) image in its
native 16:9 aspect ratio. 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: Use “Anamorphic” for regaining a 16:9 display of non-HDTV anamorphic
sources only (typically found on some DVDs, for example). For HDTV, the “Full
Screen” default will produce the same result.
Size
Size controls both the image widthand heightin tandem, maintaining the original aspect ratio
(proportion) of data from the incoming signal. 1000 = no resizing.
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. 1000 =  no vertical
stretch (i.e., native aspect ratio).
Pixel Track
(SHORT CUT: Press         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 consistentacross the screen,
and that pixel phase can be optimized (below).
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 con-
sisting of a clear pattern of tiny black and white dots, or a similar “half on, half off” graphic
image, such as the Windowsshutdown 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.

OPERATION
Pixel Phase
(SHORT CUT: Press         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 Display mateprogram. Adjust until the image is stable and each dot is clear-
ly 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

This option moves picture right and left.
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.

Blanking: Top, Bottom, Left or Right
This submenu blanks (turns 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.
Image Settings
Use any of the following slidebars, pull-down lists or the checkbox to alter your image. Refer
to Using Slidebars and Other Controls (earlier in this section) if you need help in selecting
options and adjustments. Changes made to the Image Settingsmenu are applied immediately
and are saved when you exit the menu (press        or         ).
Figure 3.13. Image Settings Menu
Contrast
(SHORT CUT: Press          and adjust the slidebar.)
Contrast increases or decreases the perceived difference between light and dark areas of your
image (0-100). If contrast is set too high, the light parts of the image lose detail and clarity. If
set too low, the light areas will not be as bright as they could be and it may be difficult to dis-
tinguish between foreground and background information. Adjust so that whites remain bright
but not distorted or tinted. For best results, keep close to 50.
NOTE:  If environment lighting changes, it may be necessary to re-adjust both options.
Brightness
(SHORT CUT: Press         and adjust the slidebar.)
Brightness increases or decreases the amount of perceived light in the dark part of the image
(0-100). If video or data is displayed with a black background, adjust until the background just
changes from black to very dark gray. For best results, keep close to 50.

Color
(SHORT CUT: Press         and adjust the slidebar.)
“Color” adjusts color saturation level, or the amount of color in a video image. For example,
setting Color to “0” produces a black and white image. If Color is set too high, the color levels
in the picture will be over-powering and unrealistic. Use          or          until the desired color
saturation level is displayed. NOTE: COLOR is not available in the RGB mode.
Tint
(SHORT CUT: Press         and adjust the slidebar.)
“Tint” adjusts color hue to obtain true color reproduction of NTSC video signals. Use         or
until you reach optimum balance of red-to-green in your image. It is best to adjust tint
while displaying a proper SMPTE color bar test pattern-otherwise, it is recommended that tint
remain at its default setting. NOTE: TINT is not available in the RGB mode.
Detail
(SHORT CUT: Press         and adjust the slidebar.)
“Detail” adjusts the sharpness of the video image. Use          or          until the display is as
sharp as possible, keeping in mind that any level of detail above 3 (default) will increase the
level of detail as well as introduce some level of noise in the image. Set below 3 to filter the
signal and remove noise from a noisy source. Keep at 3 to apply no detail. NOTE: DETAIL is
not available in the RGB mode. 
Color Temp
“Color Temp” applies either a preset color temperature (3200K, 5400K, 6500K, 9300K) or any
previously defined Interpolated or custom “User” color temperature. All temperatures are meas-
ured in degrees Kelvin and represent the “coloration” (reddish or bluish) of the whites dis-
played by the projector-the lower the temperature, the more reddish the whites, the higher the
temperature, the more bluish the whites.
NOTE: Custom temperatures (“User” or “Interpolated”) can be defined in
the Advanced Color Temperaturemenu-until then, these choices all default to
6500K. See Section 3.8, Adjusting System Parameters and Advanced
Controls.
Color Space
This option determines how the color components of an input signal are decoded for accurate
color in the display. Selecting a color space option is useful only for analog signals connected
to INPUT 1orINPUT 2. Although the color space for such a signal is automatically deter-
mined by the projector, in some circumstances you may wish to override this and manually set
a different color space. 
NOTE: For digital signals or for signals connected to INPUT 3or INPUT 4, the color space
function is entirely automatic and the pull-down list disabled.

The current color space appears in the Image Settings menu. Press         to select a different
option:
zSelect RGB unless you are using component video at INPUT 1or 2.
zSelect YPbPr(video) if you are using a standard definition televised signal (SDTV)
zSelect YPbPr (HDTV)if you are using a high definition decoder (HDTV).
Video Standard
The projector automatically detects the video standard present and displays the name of this
standard here. Press         to view or select a different video standard from a complete list avail-
able to the projector (some will appear disabled, depending on the current incoming signal).
Selecting a specific standard forces the projector to process the signal according to this stan-
dard.
NOTE: This option should remain set at “Auto” for all instances EXCEPT: 1) a poor quality
input signal or 2) a black-and-white video signal. In order to detect and display such signals,
specify the relevant standard.
Gamma
NOTE: Gamma does not normally require adjustment and is intended for experienced users
only.
The “Gamma” option affects the shape of the gamma curve representing the levels and types of
grays available between minimum input (black) and maximum (white). Generally the best
gamma curve is one that produces maximum contrast, brightness and color performance. See
Figure 3.14.
THE 1.0 SETTINGgreatly reduces apparent contrast of mid-range signals and represents a
straight transition from black to white.
THE DEFAULT SETTING OF 2.2 is a normal and smooth gamma curve recommended for
virtually all sources, producing good contrast and smooth gray transitions without distorting
colors.
SETTING OF 2.2S OR 2.8Sare not true gamma curves but are slightly S-shaped, resulting in
more intense mid-grays. If you use an “S” option, mid-levels in your display will be brighter
(they have more intensity) without whites crushing, however this abnormal grayscale will also
likely disturb color accuracy. Likewise, the 2.2SNcurve is also distorted, but can improve some
NTSC signals.
THE 2.8 SETTINGoffers more apparent contrast of mid-range signals with fewer grays, and
may appear darker than the 2.2 setting. This is the official standard for PAL and SECAM sig-
nals but it is almost never used for real signals which use 2.2.Enter

3.7 Adjusting System Parameters and Advanced Controls
Use the Communications, Preferencesand Statusmenus to display and/or alter overall system
parameters rather than those that affect a specific source or channel.
Use the Advancedmenu whenever you need to work with or replace the lamp, select a test pat-
tern, define a new color temperature, or access lesser-used image control settings intended for
experienced users.
Communications
Use the checkboxes and pull-down lists in the Communicationsmenu to alter the methods or
types of communication to and from the projector. Refer to “Using Slidebars and Other
Controls” subsection if you need help. Changes made to the
Communicationsmenu will be saved when you exit the menu. 
Baud Rate
The baud rate setting determines the speed of communications to and from the projector. By
default, the projector baud rate is set to 9600. Setting the correct speed is important when you
are controlling the projector with an external device or another projector via an RS-232 or
RS-422 port. You must set the projector baud rate at these ports to match the baud rate of the
controlling device. If you are unsure about what baud rate to choose, refer to the
documentation for the controlling device.
NOTE: 1)The baud rate setting does not affect the switcher port, which is always 9600 baud.
2) See 2.9, Serial Port Connections and Appendix Dfor more information about cable connec-
tions between devices.
