Need help with 30" Cinema Display

April 11, 2007 6:43 PM

Am I stuck using my 30" Apple Cinema HD Display at 1280 x 800 for the forseeable future?

So I bought a 30" Apple Cinema HD Display to replace my aging 23" model. I checked with my Apple rep to make sure it was compatible with my Dual 2 GHz G5. Check. Imagine my surprise when I hooked it up and saw icons the size of silver dollars! I double checked my settings, but sure enough, 1280 x 800 was the highest possible resolution, not the 2560 x 1600 I was expecting.

Turns out I need a new video card. Apparently, the best and really only "available" card that will support the full resolution is a ATI Radeon X800 XT-Mac Edition AGP. But no one has one available anywhere! Other World Computing put one on back order for me (at least 11 days out) but said they obviously can't guarantee it'll be available then. I can't even find a used one anywhere.

Am I just stuck with this resolution until someone has them available? Or is there some sort of work around? The low resolution is surprisingly irritating, so if I'm stuck with it for a while, I guess I'll just hook the 23" display back up. Thanks in advance.

You're going to have to get a new video card. No way around it.

In the meantime, me and my quad-core G5 can keep that lovely 30" warm for you. ;-)

All the macbookpros will handle it, for the record.

Uh, let me think about that, CommonSense. NO! :-)

Thanks for the dose of reality, too. Not what I want to hear, but what I already knew, deep down.

You could always give SwitchResX a try - maybe it'll open up other resolutions to display.

I've been searching Google for a firmware patch that allows Windows-based ATI cards to be used in Macs. I'd feel around forums for something along this line, since you'd then be able to buy a card, patch it and use it in your Mac sooner and cheaper than through OWC — or, better, to be able to reuse your current card, if it supports dual-link DVI with a newer firmware.

You're certain your PowerMac G5 doesn't have a PCI-Express slot? If it does, there are a wider variety of card options available to you.

There is a Nvidia 6800 Mac Edition AGP, as well as an X850 Mac Edition XT AGP, which will both support the 30" ACD.

ikkyu: No, PowerMac G5's do not have PCIE slots

FWIW, here is an ebay auction for the Nvidia 6800 AGP. (Not affiliated with seller)

SwitchResX will not work. You need a video card that is dual-link DVI capable in order to reach those upper resolutions.

Another ebay auction for the X800XT Mac Edition (auction ended w/o bidders, try contacting the seller?

Sorry for the spam. Search ebay for "ati G5" and "nvidia G5" for a lot more results.

What you might try and do is see if there is a setting on the monitor to display the 1280x800 resolution at a 1 to 1 pixel resolution. You won't be using the whole screen, but LCDs always look best when pixels are mapped 1-1. Everything should look normal size until you get a new video card.

If you'd bothered to read the link I'd provided, mphuie, you would learn that you are mistaken.

You sounded very definitive, though. Bravo.

Thanks for the update, I didn't know they supplied PCIE in the G5's. (I was almost positive that my dual 2.0 G5 was the last revision).

I have the latest revision of the dual-core 2GHZ G5, and it uses PCI-E cards. There are several inexpensive graphic card options. I bought it in Jan 2006. I hope you're in the same boat.
