Definition: VGA pass-through


A feature of a high-resolution graphics card that does not support standard VGA resolution. The VGA card in the computer is cabled to the pass-through circuit on the high-res adapter. When high-resolution is not used, the card's driver causes the VGA signals to pass through to the monitor. Pass-through circuits are also built into MPEG boards, allowing both VGA and MPEG signals to reach the monitor.




VGA Pass-Through
The signals go from the VGA card to the high-resolution adapter and then to the monitor.
