the configuration menu is recommended for experienced users/technicians only.
system configuration—general—
the first six options in the configuration menu are explained below:
language
choose from available languages to use in the projector’s menus. the change will take effect immediately.
image orientation
set the orientation of the image according to the orientation of your projector. if the setting is incorrect, projected images will be reversed and/or upside down.
fade time
set how long (in seconds) it takes to gradually dissolve one image into another for a source switch.
auto power-up
enter a checkmark to enable the projector to automatically power up after losing power due to a power failure or due to unplugging the projector during operation. note that unsaved display adjustments may be lost.
set date & time
enter/read the current year-month-day and hour-minute-second. changes here reset the projector’s real-time clock.
menu preferences—submenu use the options in this submenu to adjust the appearance, content and/or location of on-screen menus and messages.
large menu font—enter a checkmark to enlarge menus and their text. you may have to adjust “menu location” to accommodate the increased menu area.
menu location—use the pull-down list to choose a pre-defined default or customized location for the display of all on-screen menus.
to create a custom menu location quickly, choose a preset that is closest to the desired location. then adjust “horizontal shift” and “vertical shift”slidebars to move the menu to the desired location. avoid locations too close to a corner or edge to prevent cropping of larger menus.
horizontal shift and vertical shift—shift your menus as desired, creating a customized menu location.
the channel list and input dialog box cannot be hidden during use of the menus.
display slidebars—enter a checkmark to superimpose a small slidebar over the current image whenever an adjustable parameter is selected directly with a key such as contrast or bright . if “display slidebars” is unchecked, these slidebars can still be accessed, but will be hidden during adjustment. this option does not affect slidebars in menus.
display error messages—choose how you want to be notified of errors detected in either the incoming signal or projector. select “screen” or “all” (default) to see brief on-screen messages. this is particularly recommended during setup or testing of the projector. or select “rs232” to receive messages via rs232 (or rs422) serial communication only. to hide error message displays, such as during shows and presentations, select “off” or “rs232”.
system configuration—communications—
settings in the communications submenu define and control how single or multiple projectors are can link with each other and with a controlling device.
projector
enter a three-digit number (such as "001”) to assign or change a number to the projector currently in use. if the current projector already has a number assigned, that number will appear here (for example, “004” in figure 3.14, above). numerical identity for projectors enables you to communicate with a single projector within a multiple-projector application (see also proj key in 3.2, using the keypads). if you make a mistake in assigning or changing the projector number, press exit to cancel.
network routing
1) not applicable for stand-alone projectors or simple serial networks with only one type of controller and linking.
separate: select “separate” (factory default) to keep rs232, rs422 and ethernet messages on their respective paths instead of being broadcast to the other types of ports. in figure 3.15a, rs422 controls only the projector to which it is connected. in figure 3.15b, either rs232 or rs422 will control the network.
rs232 and rs422 joined: messages originating from an rs232 or rs422 controller will be relayed to all rs232 ports. any ethernet communication, however, will not.
rs232 and ethernet joined: messages to and from the rs232 ports will also be relayed to the ethernet port, and vice versa. any rs422 communications will be isolated.
all joined: all messages reach all ports, regardless of type.
ethernet settings (submenu)
notes: 1) not used for stand-alone projectors. 2) recommended for network administrators only.
dhcp: enable this checkbox if you want a dhcp server to automatically change the projector’s default ip address (0.0.0.0) to one that is valid and unique for use on the current ethernet network. on networks without a dhcp server, or to simply override the automatic dhcp server function, delete the checkmark and enter the new “ip address” settings desired. remember that only a 0.0.0.0 address will trigger the dhcp addressing service, and only when the dhcp checkbox is enabled.
ip address: enter a valid and unique ip address for use on the network to which the projector is currently connected. this address will overwrite any previous ip address such as the projector’s factory-defined default (0.0.0.0), or one that has been assigned by a dhcp server or other user. note that the projector will respond to commands sent to this address only after the next power-up, after which the address remains in effect until it is changed again.
port: on some ethernet networks, firewall restrictions may require that the port number of the projector be changed from its default of 3002. if so, enter a new valid port number here.
broadcast key
enter a checkmark if you want keypad commands sent to one projector to be relayed to all projectors in a serial network. note that the proj key will temporarily “override” the effect of a broadcast setting and allow you to control a specific projector when necessary. disable the setting for all but one (any)projector in a network.
backlight
press any key on the remote keypad.
front ir/back ir
as needed for your application, set to “on” so that the front and/or rear ir sensor locations on the projector responds to the ir keypad. set to “off” to disable.
to disable both ir sensors, you cannot use the ir remote keypad to select the second off setting. this safeguard prevents accidentally disabling an ir keypad while you are using it. instead, use either the built-in keypad or a wired remote (optional) to set the remaining active sensor to off. the projector will no longer respond to an ir remote keypad.
wired keypad
select “on” to enable use of a wired remote keypad connected to the rear of the projector. the projector will then respond to incoming commands from either port. to disable the wired keypad, you must use a different keypad—the built-in or an ir remote keypad—to select “off”. this safeguard prevents you from accidentally disabling the wired keypad during use.
system configuration—geometry & color—
in the configuration menu, select the geometry and color submenu when you need to modify overall color performance and/or image geometry for all sources.
test pattern
choose the desired internal test pattern, or select off to turn off a test pattern. alternatively, use the test key for cycling through test patterns.
vertical keystone
use to correct a keystoned image shape in which both sides of your image are inclined toward the top or bottom edge. keystone is typically caused by tilting the projector in relation to the screen, so that the lens surface and screen are no longer parallel to each other.
brightness uniformity—submenu
brightness uniformity provides further refinement of displays already matched for their primary colors and overall light output. use brightness uniformity to create an exceptionally smooth image in which no area appears brighter and/or more red, green or blue than another. in the brightness uniformity menu, enable the “uniformity enable” checkbox to access a multitude of adjustments for critical color light output control in specific areas throughout the image. your settings apply as long as the “uniformity enable” checkbox is enabled and you are using a “user” color temperature defined by the brightness uniformity controls. to disable the brightness uniformity function, delete the “uniformity enable” checkmark.
see also 3.11, using multiple projectors for the complete step-by-step procedure for achieving uniform brightness in adjacent displays.
edge blending—submenu
the edge blending submenu provides a range of controls for smoothing together the overlapping bright edges of multiple adjacent projected images to create a single larger “seamless” image. these controls, which primarily affect whitelevels, are typically used in conjunction with mechanical lens blinders (optional), which are installed on the front of the projector and which primarily affect blacklevels. blinders for this projector are not yet available.
see also 3.11, using multiple projectors.
color adjustments by x/y, and color saturation — submenus
1) for defining or changing a user 1, 2, 3, or 4 color performance or “gamut”. sometimes known as comprehensive color adjustment.. 2) factorydefined primary color levels, which ensure a specific color performance from projector-to-projector, can be altered in the service menu only. if you suspect alteration of these defaults, the factory settings can be recovered with selection of "reset to factory defaults?” in the color primary settings submenu accessed via the service menu (password-protected).
from the factory, the projector can utilize any of the 3 pre-defined color performance settings identified at right (default=max drives), or colors can be driven on the basis of color temperature.
for most applications, one of these gamuts will produce accurate and realistic colors from a variety of sources. they can be applied at any time in the advanced image settings menu (“select color adjustment”), and are not adjustable.
defining “user” color gamuts: in some cases, you may find that none of the predefined “select color adjustment” options exactly suit your needs. for example, you may require a unique color gamut (range) for a single projector or application, or you may need to precisely match colors across multiple adjacent displays. in such cases, use the color adjustments by x,y or color saturation submenu to define the precise hue of each primary color component (red, green, blue, and white) used to generate the millions of colors produced in displays. you can create up to four custom color gamuts (user 1, 2, 3, or 4) with these adjustments.
note that the two menus differ only in their user interface, so use whichever menu best suits your needs and application. a color meter can help with adjustments.
color adjustments by x,y—enter known x/y coordinates from the chromaticity graph.
color saturation—adjust color slidebars and judge image color by eye or meter.
a user-defined color “adjustment” can be applied by selecting it in the advanced image settings menu (“select color adjustment”).
color adjustment by x,y: use this submenu if you want to create, alter or copy a color gamut (i.e., “color adjustment”). controls in this menu define the precise hue of each primary color component (red, green, blue, and white) used to generate the millions of colors produced in displays. the x/y coordinates for each color define its location on the standard cie chromaticity graph (see figure 3.19)—changing either or both of these numbers will change the hue of the color, and relocate the “triangle” for possible colors. for example, changing the x/y coordinates for red may move the color closer to orange or closer to violet, which will in turn affect all displayed colors having a red component. adjust the slidebars or enter new specific coordinates as desired to define or change up to four “user” color gamuts needed for your environment and applications. apply at any time in the advanced image settings menu.
keep new x,y coordinates within the original color gamut triangle shown here.
procedure for x,y adjustments: see 3.11, using multiple projectors.
color saturation: use this submenu if you do not have specific color coordinates in mind and will simply judge color performance by eye or meter. like the color adjustment by x,y submenu, each color control actually defines new x/y coordinates for that color and changes its hue—it is just a different interface.
adjust the hue of each primary color (red, green, blue, and white) by using more or less of it in relation to the other colors.
a color saturation adjustment defines the corresponding x/y coordinates shown in the color adjustment by x,y submenu. these x/y coordinates will remain stable for this user gamut until they are changed again via either menu. values displayed in the color saturation menu, however, will likely fluctuate as you use the projector, and will be different when you return to this menu at some point in the future. these floating changes do not affect the x/y coordinates or gamut.
system configuration diagnostics / calibration
test pattern
choose the desired internal test pattern to display, or select off to turn off a test pattern. alternatively, use the test key for cycling through test patterns.
test pattern grey level
set the desired level of gray for displaying in the full gray field test pattern.
freeze image
enter a check mark to freeze (stop) an image on a single frame. this diagnostic tool is useful if you need to examine in detail a still version of an incoming image that cannot be “frozen” at the source. for example, in moving images it is sometimes difficult to observe artifacts such as external deinterlacing/resizing and signal noise. remove the checkmark to return back to normal.
color enable
select which color or colors you want to see. this is useful while working with color temperature, input levels or other special setup parameters. colors can also be enabled/disabled by entering the corresponding function code listed on the back of the standard remote keypad.
odd pixel adjustment
1) factory-set and rarely required by user. 2) source must be ]110 mhz.
when using certain rgb sources, you may need to adjust the normal gain or offset of odd pixels in relation to even pixels. this will smooth out very narrow (1-pixel wide) “checks” or vertical stripes that indicate adjacent “on” and “off” pixels. although offset and gain slidebars can be adjusted individually and manually, using the level detector simplifies this process (see figure 3.21):
1. use an external analog native-sized continuous grayscale test pattern with at
least 256-levels.
2. turn “level detector” on.
3. set “level value” to ~200. the image should now be black-and-white (or black-and-one color, if you use “color enable” function).
4. adjust offset. half of the pixels will move, the other half will not.
5. adjust until the two transition regions overlap. the stripe of noise will be minimized, defined by the value in the slidebar.
6. set “level value” to ~800. the image should now be black-and-white.
7. repeat steps 4 and 5, but adjusting gain.
8. repeat steps 3-7 for all remaining colors. your rgb source should now be ok.
1) adjust offset before gain, since offset affects gain. 2) a value of 128 represents no change in normal odd pixel offset or gain. 3) odd pixel adjustment eliminates “1 pixel on, 1 pixel off” patterns only, not any type of larger patterns.
reserved
no function.
peak detector
the “peak detector” is a fast method for defining individual input levels, and can improve the accuracy of input levels set by the auto input level function. enabling the “peak detector” activates a special operating mode for detecting only pixels that are considered black or white—all other levels are displayed as a mid-level gray.
when used with a 16-step grayscale pattern in which the two black and white bands are known to be at opposite edges of the image, you can watch these isolated areas while adjusting individual blacklevels and input drives until both bands are just visible. images from this source will then display correct blacks and whites without crushing or washing out.
level detector
the “level detector” checkbox enables a specific thresholds for blacks and whites—input levels that fall below a specified level value (see below) are displayed as black, and all others are displayed as white. it aids in odd pixel adjustment. to use:
1. enable “level detector” and display a continuous grayscale.
2. set “level value” to near black (such as 200).
3. adjust offsets to minimize area of black stripe.
4. set “level value” to near white (such as 800).
5. adjust gains to minimize area of white stripe.
level value
the “level value” defines the value to be used by the level detector in recognizing blacks and whites. see level detector, above.
