New Dual-Link Adapter on Gateway 30" Monitor, Thinks DVI!

I have the new dual-link cable attached between my macbook pro and a Gateway 30" Display. For some reason my display is only detected as having a regular dvi cable attached and won't support a resolution higher than 1920X1200. The monitor itself is capable of 2580X1600 and works on a Windows pc this way.

Do I have a defective cable or is there something I'm doing wrong?

Macbook Pro, Mac OS X (10.5.6), Gateway Extreme 1600p 30" Monitor

I have the same monitor and late-model MBP. I didn't realize that the adapters were shipping yet, but if they don't work with one of the most popular 30" displays on the market, then clearly they don't work properly.

I hate to ask, but you're certain that it's the dual-link DVI adapter that plugs both into the mini-displayport and a USB port?

I have Apple adapter p/n MB571Z/A. I'm fairly sharp with this stuff and yes it is the correct adapter. I'm using the Dual DVI cable that came with the Gateway monitor. The cable is CLEARLY marked Dual DVI.

My only remaining option is to try a different cable. I may do this but shouldn't have to since the current setup displays a 2580X1600 resolution on a Windows Vista Desktop PC using the same cable.

It seems like a strange situation.

Sorry to ask as though maybe you didn't know for sure, but I needed to be certain because my solution is to dump the new MBP and get a previous gen version. I have no qualms about doing it: The dual-link adapter situation (not included, late, expensive, not working properly) is more than enough reason for me to bail.

Thanks for the quick reply, and good luck with your situation.

The would be difficult as older macs don't use the mini display port. I don't know anyone with a newer mac with a mini display port. I do suspect it has something to do with this adapter needing to use the USB port. A little strange to me and possibly why this monitor will not work at full resolution. It always detects at the maximum Single DVI resolution of 1920X1200.

I'm keeping and eye on the forums to see if anyone has a similar problem with a different monitor. My belief is this monitor should work fine as it is more state of the art than the Apple 30" Cinema Display that I didn't purchase because it was dated technology and need of a refresh.

FYI -I found this review about Gateways monitor doing a google search. I would say it appears to be a limitation of the Gateway monitor. If this is true my monitor is for sale!


If only it worked on my powermac G5, December 16, 2008
By Patrick G. Hutchings "Mac Guy" (Los Angeles, CA) - See all my reviews

I REALLY wanted this Gateway XHD3000 30" LCD to work for my setup. 2560x1600 matches the resolution of Apple's cinema display. Plus HDMI and all the other inputs ... wow .... too good to be true!. Well, unfortunately for us Mac lovers (and we are growing in number everyday) this monitor is not compatible with our macs. Oh ... and everything in the monitor's specs indicates that is should work on my G5 powerPC power mac ... But you can only get a max resolution of 1920x1200. Gateway support says "Apple does funny things," and that "Gateway is a PC company." So alas ... while I'll had to spend more dollars .... the Apple 30" cinema display worked like a charm right out of the box. I guess I'll stick with Apple and bare the "funny" looks people give me as they see their web site displayed on my beautiful 30" Apple cinema display. I wish I hadn't wasted so much time on the Gateway. Thanks to Amazon ... return process was flawless.

Not that it matters, I suppose... But I'd like to know who it is that is diverging from the Dual-Link DVI specification. If the panel works with any brand and model of 'PC' graphics card that supports Dual-Link but does not work with Apple's Dual-Link DVI port, who is really the culprit? That's assuming it's a hardware issue.

If it's a software/driver issue, then I see no reason that this wouldn't be fixed by Apple as other third party hardware support issues are fixed by them all the time. Some might say that Apple ensuring more sales of their own displays is the reason, and they may be right, but I find that a disservice to the end user.

I'm staying steady on with the monitor as on January 9th the real reason for it's purchase will arrive: A Penryn-based PC with 3 Nvidia 1GB GTX 280's running in 3-way SLI. This year I switched to Mac after 20 years of Windows. However, after 20 years of being a hardcore PC gamer, I accepted that my changeover would come with the price of having to maintain two systems: One that can play some games, and one that can play all games, and play them at the top of their performance potential. It will be my first Vista machine, and I enjoy the humor in the fact that it will never be used for anything other than playing games. 🙂 (Anyone who understands what '20 years of hardcore PC gaming' means will know not to bother uttering the word, 'console'.)

I'm going to keep Googling around to see if I can find any evidence of someone running a previous gen MBP with this monitor. If it's a bust, I'll cross that bridge when I come to it. I may still switch back to a previous gen as I have a couple other issues with the new one, but either way, I'm still super happy that I've made the switch to OS X and I can't imagine ever going back.

Though I'll be making daily visits for things like this:

+Gateway support says "Apple does funny things," and that "Gateway is a PC company."+

So Gateway thinks Apple does funny things. I guess they feel that conforming to the VESA Plug and Display standard is a funny thing to do.

If the deficiency is in the Gateway's P&D driver, there is nothing Apple can do about it, so don't hold out for Apple to fix anything with a software update. That can't happen.

You can snoop the P&D driver within the Gateway if you want to. There is a program called SwitchRes X that allows you to do that. There is a button in SRX labeled "Print EDID" that dumps the driver to a text file. You can see if Gateway included the timing for 2560 x 1600 in the driver or not, though it sounds like they didn't. Then, if you want to call Gateway support for yourself, you can ask them to explain this omission in the driver and if there is going to be updated firmware for the monitor.

Also, if you really want to keep the monitor in spite of the shortcoming (assuming the shortcoming is really in the driver, TBD), you can use SRX to build the missing timing and include it in the resolution choices under OS X.
