CRT's will shorten but the light output will be higher. This situation is tempory, when restarting the projector, the drive mode is
automatically set to normal.
-permanent boost : higher drive current to the CRT's, the lifetime of the CRT's will shorten but the light output will be higher. This setting will be saved in the EEPROM. When restarting the projector, it will start up in boost mode.
