rray. An improved VGA monitor
standard that provides at least 256 simultaneous colors and
a screen resolution of 1024 x 768 pixels.
Vertical Blanking Interval (VBI)
The time it takes the beam to fly back to the top of the screen
in order to retrace the opposite field (odd or even). VBI is in
the order of 20 TV lines. Teletext information is transmitted
over 4 of these lines (lines 14-17).
