[Àû¿ë´ë»ó: 0.74_SVN_new, DOSBox-x]

If set, changes to the Display End register of the CRTC do not trigger DOSBox to resize it's window
IF the value written is less than the current value.

Some demos like DoWhackaDo need this option set because of the way it's raster effects work. If the DOSBox window rapidly changes size during a demo try setting this option.

Else, leave it turned off. Changes to other VGA CRTC registers will trigger a DOSBox mode change as normal regardless of this setting.
