ADJUSTING AN IMAGE FOR KEYSTONE CORRECTION
1. Enable keystone adjustments by selecting Keystone from the Geometry Correction drop down list.
NOTE: This will enable the controls for performing 1D or 2D keystone adjustments.
2. Select a Test Pattern. NOTE: It is recommended to use the Grid test pattern.
3. Perform coarse keystone adjustment by using the Horizontal or Vertical Adjust setting. Use the left and
right arrow keys to make the adjustment. NOTE: The corner cursors are a guide as to how the image will
be adjusted. The outside edge of a cursor will be the outside edge of the image. It may not be possible to
exactly match the screen dimensions with the Horizontal and Vertical Keystone controls, but these settings
can be refined when the 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 E

8. Use the arrow keys to move the selected corner to match the screen.

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 co-
ordinates must be adjusted, or the free run frequency must be changed to fall within the allowed bandwidth.

• 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
checkbox 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 checkbox is enabled. While making
adjustments, enable the Coarse Adjustment checkbox 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.
