Four Screens, two GPU's and one Big Desktop

[locksley]

On tech spot theres no mention of multiview across multiple GPUs only on fireGL. where did you find the info.

[locksley]

yeh, crap, i just read the AMD PDF, only supported on ATI Radeon 3000 and 2000 series.

Anybody got any ideas?

In the past i have done this with lesser cards using Xinerama.

which pdf ?

"Multiview" is ATI marketing-speak for Xinerama.

It's the same case with Nvidia.

[bridgman]

It's not Xinerama though, same end result but completely different implementation AFAIK.

OK, so the good news is that the release notes say that we've enabled Multiview on Radeon (ie consumer) cards, not just professional products (used to be Fire* only before).

If Multiview is enabled on 2000 and 3000 but not 4000 that probably just means more testing or bug fixing is needed, not that we don't plan to support it.

Oops, you are correct:

from http://www.phoronix.com/scan.php?pag...ultiview&num=1

MultiView also allows for OpenGL acceleration across all displays and does not rely upon Xinerama.

I haven't had to set up multimonitors with ATI for a while -- I guess I'm a little out of the loop.

ok, just took the gun out of my mouth

Was busy making Vista my home

So what can we do. I have tried enabling Xinerama but i can only use one pair of monitors at a time the other don't even show in CC.

Any suggestions.

Here's the PDF i was referring to.

I'll ask around; if we say it's supported on HD2/3xxx and not 4xxx then it's probably disabled in the driver code for now.
