Video Graphics Array


 * Analog RGB video with seperate Vertical and Horizontal signals.
 * 0,7 V peak-to-peak
 * 75 ohm impedance (9,3mA - 6,5mW)

Standard resolution frequencies (think text console screen):
 * Clock frequency 25.175 MHz
 * Line frequency 31469 Hz
 * Field frequency 59.94 Hz

Beware that the HD15 connector is a 30Ω impedance device. Maximum cable length is usually 15 meters with good shielding.
