looking at device manager in xp, i noticed that my graphics card (radeon x850) is listed under display adaptors, followed by another entry : radeon x850 series - secondary
is this normal? both have the same details for drivers and resources. should i remove one?:confused:

It's normal for ATi's that support dual monitors. ;)

yes all ATI Radeon 8000 series and above automatically supports 2 monitors, regardless if the physical connection is there or not.

you can dissable the 2nd card to save system resources if you don't use it

Actually, _all_ Radeons except the original Radeon (aka 7200) do support dual monitors in this way - including the Radeon VE aka 7000 and the 7500.

My PCI All-In-Wonder VE (7500 chip) doesn't, oddly enough.

That's because you can strap the Radeon chip to hide its 2nd instance when you're designing a single-headed card. I'm sure ATi did know that trick when they made that AIW :)

Yeah, it's just that I've seen some Radeon cards show two instances of itself in Device Manager, despite only having one monitor port. I'm sure these weren't BBAs though.

What Peter said contradicts what you said, so that doesn't do me any good.

No they aren't. I wish you'd check your facts ... 7000 and 7500 are dual head capable - the 7200 is the ONLY Radeon chip that isn't.

If these are implementing the TV-out as an independent head, then it's perfectly fine like that.

No, these weren't AIW or otherwise TV-capable cards. In fact, the one VGA port was the only port on the card at all. I wish I could remember what kind of card and what Radeon chip it was. I think it was a Celestica Radeon 7000, but I can't remember for sure.
