Dynamic Astigmatism (spot shape adjustment)

The spot shape adjustments correct the spot shape in 8 different areas on the screen and that for the three colors separately. The spot shape is adjusted according to the axial axises and the diago- nal axises when using the arrow keys on the RCU.

These adjustments have to be done on a dot pattern (e.g. the inter- nally generated pattern) with standard line frequency (15 kHz). The adjustment values are stored in the EEPROM and remain the same for all frequencies.

Follow the next procedure:

Highlight ‘Dyn. Astigmatism’ by pushing the joy stick forward or backward and press ENTER to select.

EXIT returns to the path selection main menu.

Select the source type, selected source or genlock pattern, by high- lighting the color for which the spot shape has to be corrected and press ENTER.

e.g. when selecting RED under ‘on genlocked pattern’, the projec- tor switches to a genlocked pattern.

Press ENTER to continue adjustment.

Increase the contrast level using the Contrast Control to near maxi mum. Using that “+” Sharpness Key, defocus the image until the dots are large and easily visible. Press ENTER to continue to SEL.

SEL : select the adjustment area on the screen where the spot shape has to be corrected.

Use the arrow keys to select one of the 8 areas. Press ENTER to continue to ADJ.

ADJ : adjust the spot shape in the axial or diagonal direction when using the arrow keys for the selected area. Adjust until the spot shape is circular.
