from your presentation, you can 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 3 2 to quickly access the “gamma” 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 without traveling through the menu system (note: available for certain display parameters only). for example, press cont to access the “contrast” slidebar immediately. press exit to return to your presentation.
before you begin
use auto setup (auto setup)
for a good and efficient first step in perfecting the image, press auto setup . this initiates an automated process in which the projector quickly optimizes critical display parameters such as size, position, pixel tracking, etc., based on the type of incoming source data detected. an auto setup can save considerable setup time, and you can still modify the adjustments as desired using menu options described below.
in the size and position menu in the size and position menu, you can 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 used at the site.
refer to "using slidebars and other controls" (earlier in this section) if you need help using any of the options and controls. changes made in the size and position menu are applied immediately and are saved when you exit the menu (press exit or menu ).
resize presets
select a resize presets option to quickly display an image in its native resolution or to automatically resize an image to closely fill the projector’s native resolution of 1400 x 1050, or to optimize the width or height of your display. size, position and blanking parameters will automatically adjust accordingly. or, if blanking is set first, which defines an active input area, resize preset scaling will occur in this region of interest only. resizing options are explained in detail below.
what is the resizing default? by default when displaying a new source, your image will utilize as much of the projector’s display area (1400 x 1050) as possible for the type of incoming source data, but with minimal or no changes to aspect ratio. see select “default” below.
when “custom” appears: the “custom” re-size descriptor automatically appears in the size and position menu when any of the values for size, vertical stretch, hposition, v-position or blanking do not correspond to those for a preset. this option is not offered in the resize presets pull-down list.
select “default” for most sources (factory default). the image will be centered and displayed as large as possible depending on the type of source, as described below:
1 a 5:4 graphic image will enlarge to fill the screen height, and be centered between narrow black side bars.
2 a video image or 4:3 graphic image will enlarge to fill the screen width.
3 an anamorphic (16:9) image will fill the width and be centered between black bars on top and bottom.
select “no resizing” to display the image in its native resolution, which may be smaller than the projector’s 1400 x 1050 resolution. for example, for a source with a native resolution of 800 x 600, “no resizing” will center a small image within a black border—the black border areas are unused areas. see below.
select “full screen” to use all pixels (1400 x 1050) for displaying the image, regardless of source or original aspect ratio. incoming source material having a different aspect ratio than the projector will be stretched for display.
select “full width” to fill the projector’s display from left-toright without changing the original aspect ratio of the image.
depending on the source, data at the top and bottom may be discarded (cropped), or the display may have black borders at the top and bottom (called “letterboxed”).
select “full height”to fill the display from top-to-bottom.
depending on the source, this may create borders.
select “anamorphic” to display an anamorphic image in its native 16:9 aspect ratio. the image will fill the screen from side-to-side, and be centered between narrow black bars on top and bottom.
size
“size” controls both the image width and height in tandem, maintaining the current aspect ratio (proportion) of the displayed signal data.
vertical stretch
“vertical stretch” adjusts the height of the image while keeping the width constant. use “vertical stretch” to change the aspect ratio of the display.
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.
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
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.
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.
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
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”.
pip enable
toggle to display from two sources at once (picture-in-picture) or the primary source only. this checkbox turns the secondary source on and off in the display. note: not available in v1.0 software. shown as “reserved”.
advanced size and position—submenu
this submenu consists of the following options:
active input window: this read-only value indicates the current size (i.e., area) of your displayed data or “region of interest” as defined by the blanking controls. by default, the projector automatically determines what portion of its full resolution to use, and pixels in the surrounding borders are turned off. you can also specify a specific active input window size by adjusting one or more “blank” settings. for example, if you have blanked (cropped) 100 pixels from both the left and right edges of an incoming source of 1400 x 1050, the remaining active input window will be reduced to 1200 x 1050. when using sd or hd or a decoded video source at input 3 or input 4, the default blanking of “0” defines an active input window of 720 x 483.
blanking (top, bottom, left, and right): crop the image as desired so that unwanted edges are removed from the display (changed to black—see right). blanking defines the size of the active input window, or area of interest. range of adjustment depends on the source resolution and other factors.
plug & display (edid): by default, a plug & play (edid) source outputs a signal according to the edid information provided by the projector. to override this information and display in a different format (for example, if your plug & play [edid] device does not support the projector’s resolution and/or frequency), select the desired plug & play (edid) resolution from the list.
any daisy-chained projectors will also display according to the chosen plug & play (edid) format.
edid=extended display identification data standard.
image settings menu
use options in the image settings menu to alter your image without affecting its size or position. changes made to the image settings menu are applied immediately and are saved when you exit the menu (press exit or menu). options not available for the projector model or source are disabled and appear dim (gray).
contrast
(short cut: press contrast and adjust the slidebar.)
“contrast” increases or decreases the perceived difference between light and dark areas of your image (0-100). for best results, keep close to 50. 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 the overall image will be dim. for best results, start with a low value and increase so that whites remain bright but are not distorted or tinted, and that light areas do not become white (i.e., are “crushed”).
if the environment lighting changes, an adjustment of gamma is recommended (see below).
brightness
(short cut: press bright and adjust the slidebar.)
“brightness” increases or decreases the amount of black in the image (0-100). for best results, keep close to 50. start with a high value and decrease so that dark areas do not become black (i.e., are “crushed”). conversely, high brightness changes black to dark gray, causing washed-out images.
gamma
“gamma” is a global setting that determines what gray shades are displayed between minimum input (black) and maximum input (white) for all signals. a good gamma setting helps to optimize blacks and whites while ensuring smooth transitions for the “in-between” values utilized in other colors. thus, unlike “brightness” and “contrast” controls, the overall tone of your images can be lightened or darkened without changing the extremes, and all images will be more vibrant while still showing good detail in dark areas.
the normal gamma setting of 2.2 is correct for virtually all signals and conditions. if excess ambient light washes out the image and it becomes difficult or impossible to see details in dark areas, lower the gamma setting to compensate. this will improve contrast while maintaining good details for blacks. conversely, if the image is washed out and unnatural, with excessive detail in black areas, increase the setting. again, good gamma improves contrast while maintaining good details for blacks.
filter
the proper filter setting is automatically set for virtually all signals, and rarely needs to be changed. it applies a low pass filter for noise reduction in the incoming input signal, particularly for hdtv or sdtv. applied in the analog domain before sampling, this filtering removes high frequencies and thus reduces pixel phase noise (note this also reduces signal bandwidth). override only if standard pixel tracking and phase adjustments do not adequately clear up a “noisy” video signal, or if a graphics signal appears overly “soft”. both instances indicate that “filter” may be set to the wrong option.
detail
“detail” adjusts the sharpness of a video image so that edges remain clearly defined. it can be particularly useful if a significant “noise reduction” adjustment has caused the image to appear too soft. adjust until the display is as sharp as desired, keeping in mind that because “detail” adds some high frequencies back into the image, it can also re-introduce a certain degree of noise.
noise reduction
“noise reduction” is similar to the “filter” control, but operates in the post-sampling digital domain with a more subtle effect. higher settings are most useful for clearing up noisy rgb images such as those from a pc. adjust as desired, keeping in mind that reducing noise (which reduces high frequencies) may also soften the image.
color space
“color space” determines how the color components of an analog input signal are decoded for accurate color in the display. selecting a color space option is useful only for analog signals connected to input 1, input 2, input 5 or input 6. although color space for these analog signals is automatically determined by the projector, in some circumstances you may wish to override this and manually set a specific color space.
for digital signals or for signals connected to input 3 or 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 enter to select a different option:
select rgb unless you are using component video at input 1, 2, 5 or 6.
select ypbpr (video) with a standard definition televised signal (sdtv)
select ypbpr (hdtv) with a high definition televised signal (hdtv).
when certain rgb signals are first connected, the projector may not initially recognize them as rgb and will incorrectly decode their color information as ypbpr (video). these signals can include:
rgb signals in ntsc, pal, secam frequency ranges
scan-doubled sync-on-green
scan-quadrupled sync-on-green
for these signals, change the color space to rgb, then define a new channel for future use.
video options—submenu
this submenu is used with video sources only (inputs 3 or 4).
enable decoder agc: automatic gain control (agc) affects decoded video images only. enter a checkmark (default) in most instances—this activates the decoder’s agc circuit to ensure properly bright images. delete the checkmark if a decoded video image exhibits strange color artifacts such as stripes in highly saturated colors, indicating an incompatibility between this source and the agc.
selecting a specific standard forces the projector to process the signal according to this standard.
generally, use “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, select the relevant standard from the list.
input video black—this control compensates for incoming elevated black levels present in certain video signals, and ensures that blacks in the display are neither crushed (i.e., where dark grays appear black) nor excessively elevated (i.e., where blacks appear dark gray). by default, the projector automatically determines the best setting according to the type of incoming video signal:
0 ire–used for dvd output with “enhanced black”, secam, most pal standards, and japanese ntsc.
7.5 ire–used for most ntsc video signals.
for some types of video, you can override the setting. the control is disabled for other types of video (and all graphics sources). generally, if black appears crushed when brightness = 50, choose “0 ire”. if black appears excessively elevated, use “7.5 ire”.
color—this slidebar adjusts the color saturation level, i.e. the amount of color in a video image. lower settings produce less saturated colors — for example a setting of “0” produces a black and white image. if the color level is too high, colors will be overpowering and unrealistic.
tint—this slidebar adjusts the red/green color hue for true color reproduction of video and hdtv signals connected to input 3 or 4. for best results, adjust tint while displaying an external test pattern—otherwise, it is recommended that tint remain at its default setting.
decoder luma delay – this control affects any incoming composite or s-video signal, delaying the luma signal (intensity) in relation to the chroma (color). in the image, increasing the luma delay will move luma (seen as a shadow where colors overlap) to the right slightly, with colors remaining in place. decreasing this delay will move the shadow slightly to the left. if necessary for your current source, adjust so that no shadows occur with adjacent colors.
