What's the ADC port for?

Why does ATI put an ADC port on their newest gfx cards (X800 and X850) instead of 2 DVIs? And why not include an ADC to DVI adapter? I thought ADC was an older interface... but as I'm new to the mac world I was curious about this one.

Anybody know?

I would imagine it is because not everybody has a DVI monitor or DVI/ADC converter. Just a thought though. :black:

ADC uses the DVI standard technology, but includes more pins used for powering the monitor (well, they used to at least). If you ever look at the previous models of Apple monitors, you will notice that they did not have spot for a power cable. There was an optional ADC->DVI box they sold, which was basically a power supply for the monitor.

Right... I was just curious because they sent me 2 DVI to VGA adapters with my X800 and it only has 1 DVI port on the card. That seemed odd to me.

Me neither... but apparently ADC is still popular, since ATI is still building it onto their top-end gfx cards.

That is strange that ATI is still putting that on. I never cared for ADC... Using one cable was nice... But it rendered the monitors worthless unless you were using a newer Mac... Or unless you spent $150 for the adapter.

That might be why they still put ADC on their cards. It's cheaper for those of us with DVI to buy a $29 adapter than for the people with ADC to buy a $90 adapter.

Just speculation!

I think they put ADC on b/c it is easier and cheaper to convert adc for DVI/VGA monitors than the other way around. Now as to why they sent you two DVI to VGA dongles... well... Hmmm... I haven't a clue. Sounds like a mistake was made somewhere either in the decision making or the implimentation.
