Adjusting The Main Image - Christie Mirage M Series User Manual

3. Perform coarse keystone adjustment by using the Horizontal or Vertical Adjust setting. Use the
left and right arrow keys to make the adjustment.
The corner cursors are a guide as to how the image needs to be adjusted. The outside edge of
a cursor is 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, click OK.
A message is displayed indicating that the projector is processing the request. The settings are
applied to the displayed image, and take approximately 10 seconds. If vertical keystone
adjustments have been made, starting to do any horizontal keystone adjustments erase the
vertical settings, and vice versa.
5. After the Horizontal or Vertical adjustments have been made, selecting 2D Keystone
adjustments retains 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. The current corner is displayed in red.
7. Press Enter to select the corner. The current corner is displayed in green.
8. Use the arrow keys to move the selected corner to match the screen.
9. To save that position for the corner press Enter again.
10. Repeat Steps 6 to 9 to adjust all four corners until they match the screen.
11. To apply the new corner positions to the image select OK. A message is displayed for
approximately 10 seconds indicating that the projector is processing the 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 appears on the on-screen display, indicating
that the bandwidth has been exceeded and the keystone cannot be applied. The cursor co-ordinates
for keystone adjustment remains at the failed keystone position. This allows 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.
The Func+Help key combination immediately disables 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 does not overwrite their settings. If
keystone is enabled again, the same image corruption may occur. After pressing Func+Help,
Christie recommends to immediately reset keystone settings, which sets all keystone co-ordinates
to zero.

Adjusting the main image

Use the Image Settings menu to alter your main image without affecting its size or position.
Changes made 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 (grey).
• Contrast—Contrast increases or decreases the perceived difference between light and dark
areas of your image (0-100). For best results, keep close to 50. Start with a lower value and
