Signal Timing for a 60Hz, 640x480 VGA Display
R
same signal timings as CRT displays. Consequently, the following discussion pertains to
both CRTs and LCD displays.
Within a CRT display, current waveforms pass through the coils to produce magnetic
fields that deflect electron beams to transverse the display surface in a “raster” pattern,
information is only displayed when the beam is moving in the “forward” direction—left to
right and top to bottom—and not during the time the beam returns back to the left or top
edge of the display. Much of the potential display time is therefore lost in “blanking”
periods when the beam is reset and stabilized to begin a new horizontal or vertical display
pass.

The size of the beams, the frequency at which the beam traces across the display, and the
frequency at which the electron beam is modulated determine the display resolution.
