Anyone using a 30" Dell LCD @ 2560x1600?

I've had trouble installing 10.4.8 because of video card issues (I get 800x1280 or 1600x2560, garbled as choices). I was using a 7800GT, which I thought should be very compatible (LOL, I did get rid of 2 8800GTXs to be Mac compatible), but I guess its not.


Anyway, I wanna go with Leopard, and want 2560x1600 (which needs dual-link). Anyone have this setup? If so what card are you using? Are there any cards out there that'll just work, or work easily with Leopard and have dual-link?


I have the 7800GT, a 6200LE (without dual link) and a Radeon 2400 PRO at my disposal, but I'm prepared to buy another card. Any recommendations?

Which 8800GTS do you have? Or does it matter?

<EDIT> My bad, I just noticed your sig.

Also noticed that you managed to get it running on a 680i, nice! Are you able to use RAID under leopard?


Did you use any special driver packages or kexts, or did it work right away? And you have QE/CI?


Thanks a lot!

Which PCIe / PCI Express / PCI X card (s) have driver support for 2560 x 1600 resolution on a Leopard or Snow Leopard?


It could be any brand. NVidia, ATI or other.


Preferably it can fit an Advanced Dock for T61.

As I understand it, I will need a full-height, half-length PCIe video card.


Please advise.
