PowerMac G5 issue in Tiger OS: cannot output 2560 x 1600 on my 30" Cinema Display

[sheapuppy]

Hi everyone,

I had been running Tiger OS X 10.4.11 for a long time - very stable for my Classic OS 9 apps. About a week ago, my logic board died so I ended up buying off FB a PowerMac G5 (7,3) with 8GB RAM, Dual 2.0 GHz 970 CPUs, and an ATI Radeon 9200 128MB PCI card. I swapped my 250GB SSD drive and the new G5 booted up with no issues EXCEPT that I can only get 1200 x 800 resolution. I thought maybe it was an issue with the card itself, so I put the original NVIDIA GeForce FX 5200 64MB AGP card. With either card, I can only get 1200 x 800 resolution.

My understanding is that both of these cards support dual link DVI display.

I'm using a 30" CinemaDisplay with the original "W" cord (DVI, USB, Firewire) that came with it, so I'm not sure what's going on? Hopefully someone can help me.

TIA...JP

Neither of them do.

Neither of them do.

Thanks! I could've sworn that they did but obviously I must be wrong (dang AI ! ). Which one would you recommend that doesn't break the bank? I'm mainly using it for Photoshop as I still have an original Adobe CS license!

ATI Radeon 9650 XT (one single-link, one dual-link DVI)
NVIDIA GeForce 6800 GT DDL (two dual-link DVI)
NVIDIA GeForce 6800 Ultra DDL (two dual-link DVI)

Best regards...JP

This one. It’s even passively cooled.
