Does my DVI-I connector have any blanking time overhead?
Posted on 2007-07-25
I have a Radeon 9000 pro card. The card has both a DVI-I connector, and a VGA connector. I have it connected to a LCD monitor using a DVI-I cable that's connected to the DVI-I connector on the card.
How am I to understand the data that's going thru this connector. I have two choices:
* I assume that since the connector is DVI-I, it will have support for a VGA monitor, and therefore if I reduce the blanking overhead of the card, I'll improve the card's performance.
* I assume that since the card has both a VGA connector and a DVI-I connector, that the DVI-I connector will have no blanking overhead, since the manufacturer of the card will be assuming that anyone who is going to use the card with a VGA monitor, will simply use the VGA connector.
Which of these is correct?
