8.0 ADJUSTING THE IMAGE
R599790 - FORCE Series User Manual 63
2D keystone settings are adjusted.
4) When adjustment of the corners is complete, select OK. NOTE: A message will be displayed indicating that the
projector is “Processing request”. The settings are applied to the displayed image, and will take approximately 10
seconds. If Vertical Keystone adjustments have been made, starting to do any Horizontal Keystone adjustments
will erase the Vertical settings, and vice versa.
5) After the Horizontal or Vertical adjustments have been made, selecting 2D Keystone adjustments will retain
these settings. Fine adjustment can now be made by moving any single corner separately.
6) Use the arrow keys to move to the required corner. NOTE: The current corner will be displayed in red.
7) Press ENTER to select the corner. NOTE: The current corner will be displayed in green.
8) Use the arrow keys to move the selected corner to match the screen.
9) Press ENTER again, to save that position for the corner.
10) Repeat Steps 6 to 9 to adjust all 4 corners until they match the screen.
11) Select OK to apply the new corner positions to the image. NOTE: A message will be displayed for
approximately 10 seconds indicating that the projector is “Processing request”.
Under certain combinations of extreme keystone co-ordinates and specific signal frequency, a keystoned image
may result that is outside the bandwidth limitations of the projector. When attempting to apply the keystone settings,
a message will pop up on the OSD, indicating that the bandwidth has been exceeded and the keystone cannot be
applied. The cursor co-ordinates for keystone adjustment will remain at the failed keystone position.
This will allow the user to make minor changes and attempt to reapply the corner settings. Either the coordinates
must be adjusted, or the free run frequency must be changed to fall within the allowed bandwidth.
The FUNC+HELP key combination will immediately disable the Keystone, Brightness Uniformity, Edge Blending
and Black Level Blending features. This is helpful when, in some extreme keystone configurations, some image
corruption may appear and/or the menus may not be readable. Although FUNC+HELP disables these features, it
will not overwrite their settings. If keystone is simply enabled again, the same image corruption may occur. After
pressing FUNC+HELP, it is recommend to immediately “Reset Keystone Settings”, which will set all keystone co-
ordinates to zero.
Brightness Uniformity
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
than another. In the Brightness Uniformity menu, enable the Brightness Uniformity Enable check box to access a
multitude of adjustments for light output control in specific areas throughout the image.
Your settings apply as long as the Brightness Uniformity Enable check box is enabled. While making adjustments,
enable the Coarse Adjustment check box to apply Brightness Uniformity settings with a large granularity. Coarse
Adjustment helps identify brightness changes and accelerates projector response time while adjusting settings. To
disable the Brightness Uniformity function, delete the Brightness Uniformity Enable checkmark.
What is Brightness Uniformity
When used to refine screens already matched for their primary colors: Matching Colors in Multiple Screens and
overall light output, proper adjustment of Brightness Uniformity can create an exceptionally smooth screen in which:
• No area of the screen appears more red, green or blue than another
• No area of the screen appears brighter than another
• Color and light output from one screen closely matches adjacent screens
Although the Brightness Uniformity control can be used for a stand-alone projector, it is particularly useful for setting
up and maintaining tiled images that form a cohesive display wall in which the color “cast” and light output appear
uniform throughout each image as well as throughout the entire wall.
The procedure provided here assumes a multiple-screen application.
IMPORTANT! Before you begin.
Read through the entire procedure before attempting to adjust Brightness Uniformity controls, and keep in mind the
following checking list of prerequisites and guidelines:
• ADJUST COLORS FIRST—Always adjust the primary colors, before attempting to work with Brightness
Uniformity. This ensures that primary colors, color temperature, and maximized light output are all well matched
from one screen to another. These matches are needed before you can achieve good brightness uniformity
results
• RUN LAMP FOR 100 HOURS—Light output and brightness uniformity can vary significantly during the first 100
hours of lamp use. For best results with new lamps, either set up brightness uniformity after this period, or do an
initial setup and re-check at 100 hours.
• SET LAMP POWER—Ensure that each Lamp Power setting is as high as possible for your application while still
