2490 EQ before too large
The interval during which pre-equalization pulses occur
cannot be greater than the vertical sync pulse delay.
Decrease EQ Before.
Increase the vertical sync pulse delay.
2495 EQ after too large
The interval during which post-equalization pulses occur
cannot be greater than the interval between the end of the
vertical sync pulse and the end of the shorter vertical blanking
interval between fields with interlaced operation.
Decrease EQ After.
Decrease the vertical sync pulse width.
Decrease vertical sync pulse delay.
Increase the vertical period (in lines).
Decrease the vertical active.
2496 EQ after too large
The interval during which post-equalization pulses occur
cannot be greater than the interval between the end of the
vertical sync pulse and the end of the vertical blanking.
Decrease EQ After.
Decrease the vertical sync pulse width.
Decrease vertical sync pulse delay.
Increase the vertical period (in lines).
Decrease the vertical active.
2550 Not enough video memory
The generator does not have enough memory space to store
the total number of active pixels required for one picture.
Decrease the vertical active.
Decrease the horizontal active.
2704 Horizontal physical size too small
The physical horizontal size must be greater than zero.
Change the horizontal physical size to a positive,
nonzero, value.
2705 Invalid physical size units
An invalid physical size unit of measure exists in the file.
Reedit both physical sizes.
