Adjusting The Image; Automatically Optimizing Display Parameters - Christie M Series User Manual

Adjusting the image

Learn how to adjust image geometry so it displays correctly.
The most commonly used options for image adjustments are accessed through two menus: Size and
Position (Menu 1) and Image Settings (Menu 2), both of which appear in the Main menu. From
either of these two menus, you can change settings affecting the image from the current channel by
working with the appropriate slide bars, check boxes and pull-down lists. Exit returns to the previous
menu (or to the presentation, if from the Main menu) and accept any changes you may have entered.
Settings are saved with the current channel.
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 24 to
quickly access the Color Space option in the Image Settings menu.
For certain options, preference may be to use a direct key from presentation level to go directly to a
particular option without traveling through the menu system (available for certain display parameters
only). For example, press Contrast to access the "contrast" slide bar immediately. Press Exit to return
to your presentation.
To hide direct slide bars, disable the Display Slide bars check box in the Menu Preferences menu.
To hide the entire menu system from view, turn off the on-screen display by pressing OSD then the
Down Arrow Key.

Automatically optimizing display parameters

Automatically optimize critical display parameters such as size, position, and pixel tracking based on
the type of incoming source.
The best auto setup is obtained under the following conditions:
• Input levels, it is best to have an image with saturated (very Bright) colors.
• Phase, high contrast edges are needed.
To determine active window size:
• Video images should have whites and blacks in the image
• Wide range video images should have content (including white) that extends to all edges of the
image.
All digital and decoder option cards do not present an additional auto setup menu since digital
hardware provides enough information to perform the correct auto setup.
Analog PC graphics sources (four/five-wire sync) present a list of formats based on the current active
lines detected in the video.
Analog Video Sources (three wire sync on green) always have the options Default and Advanced.
Video sources use a look up table to determine their format based on video standards. The Advanced
auto setup selection measures the start pixel and start line whereas Default uses the table values as
is.
To start the optimization, press Auto.
In some cases for analog video a menu may appear that presents multiple choices that allows
the user to select the format that best suits their source. This selection helps the auto setup
