  • Blank monitor for an instant

    I'm looking for a way to send a signal to the video
    monitor to blank the screen for a 1/2 second or so
    while switching between screen resolutions, etc.
    There used to be a way to poke a memory location.
    Not looking to power off/on.
    How long is an idea? Write it down.

    Code:
    %ON = -1 : %OFF = 0
    '=========================
    Sub VGAoff(BYVAL BlankIt%)
    '-- Turns VGA display on/off by disabling refresh
    LOCAL disable?
    if istrue(BlankIt%) then incr disable?
    !  mov ah, &h12
    !  mov al, disable?
    !  mov bl, &h36
    !  int &h10
    END SUB
