* [[_AUTODISPLAY]] is on by default and displays the screen at around 30 frames per second (normal vertical retrace speed).
* [[_DISPLAY]] disables automatic graphic displays, but it also eliminates having to use PCOPY or page flipping when used correctly. Placing _DISPLAY after screen draws or other screen changes assures completion of the changes before they are displayed. The speed of QB64 code execution makes this a viable option.
* The [[_AUTODISPLAY (function)]] can be used to detect the current display behavior.
