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
diagonal axises when using the arrow keys on the RCU.
These adjustments have to be done on a dot pattern (e.g. the internally
generated pattern) with standard line frequency (15 kHz). The
adjustment values are stored in the EEPROM and remain the same for
all frequencies.
