Geometry Adjustments
What can be done ?
The geometry adjustments have to be done only on the green image. These adjustments are automatically implemented for the other
color images. The following adjustments can be adjusted Left-right (EW) and Top-Bottom Corrections, Blanking, Horizontal Amplitude,
Vertical Amplitude, Vertical Linearity and Horizontal Phase.
Start Up
To start up the geometry corrections, handle as follow :
1. Push the cursor key é or ê to highlight 'Geometry' (menu 1).
2. Press ENTER to select.
The Geometry menu will be displayed on the screen (menu 2).
Important
The convergence corrections are disabled during geometry corrections. The blanking corrections are only enabled during the
blanking adjustments.
Green Convergence On/Off
Why switching your green convergence on or off ?
The adjustments for a good image should be done with the geometry corrections prior to the convergence corrections as the power
consumption (head production inside the projector) will be lower. With a lower head production, the stability of the electronics will
increase. So, start by switching off the convergence and adjust first all the geometry corrections. Switch on the convergence again
and if a misalignment is still visible, correct that with the convergence corrections.
How to switch of the Green Convergence ?
1. Push the cursor key é or ê to highlight 'Green Convergence' (menu 1).
2. Press ENTER to toggle between ON and OFF.
