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

Travis B, I will be very curious to hear whether your Gateway works with older MBPs when you get to try it on Jan. 5th. I have to say, the Gateway driver of your particular monitor looks to be well formed. So if this particular monitor doesn't work with your new MBP and the DisplayPort to Dual-Link DVI Adapter, then the fault will lay with Apple.

You can see under Descriptor #1 in the EDID data you posted, the native timing for the panel is included in Gateway's driver. A Mac should pick this up and thus include that format/timing under Displays preferences as one of the choices. If that's not happening, the problem is Apple's.

Pete1961, that information posted by Travis B is the driver data that is resident in all Mac compatible monitors. A Mac is able to import and use that data over a communication channel that is embedded in every video cable. Ordinarily you don't need to do anything heroic because it all is meant to be plug-and-play simple and behind the scenes. Sometimes, when a monitor's P&D driver is missing a specific timing, you can use a utility like SwitchRes X to custom author a timing. When you do this, it gets written to a standard OS X file and becomes a part of that file.

About your question about reversibility, if you happen to make a custom timing that the monitor won't work from and you get a blank screen, it's not such a big deal with a notebook computer because you still have a usable built-in screen and that makes it easier to deal with the situation. You can always delete the OS X file with the data in it, so in that sense it is always reversible.

I am also running firmware v1.01. I don't have the dual-link adapter, so I didn't bother trying to add a custom resolution.

While I don't fully understand the contents of the driver file, I find it curious that 2560x1600 is missing from this section:

Standard Timing Identification:

#0: 1920 x 1440 @ 60Hz (D140)
#1: 1856 x 1392 @ 60Hz (C940)
#2: 1792 x 1344 @ 60Hz (C140)
#3: 1600 x 1200 @ 60Hz (A940)
#4: 1400 x 1050 @ 60Hz (9040)
#5: 1280 x 960 @ 60Hz (8140)
#6: 1280 x 1024 @ 60Hz (8180)
#7: 1152 x 864 @ 60Hz (7140)

Would someone that owns a Gateway 30" be willing to try the following:

Go into Displays preferences and turn on "Show displays in menu bar"
Click on the resulting icon in the menu bar to produce the drop down menu.
In the drop down menu navigate to "Number of Recent Items" and set it to 10.

Now drop down the menu again and see if 2560 x 1600 appears as a selection. You may need to restart, too, for the change to take affect.

I'd be curious to know if this works or not. The above method has been used by a lot of people to get 1920 x 1080 at 60 Hz (a.k.a. "1080p") to show up in Displays preferences for their HDTVs when it didn't work, plug-and-play, out-of-the-box as expected.

this did not work.

ok, to be more precise: setting the choices to 10 and rebooting did not work.

my gateway XHD3000 ran 2560x1600 quite nicely from a linux machine via the same cable. it is only with the $99 Apple converter that the Macbook cannot see the higher resolution that the monitor is capable of.

I also know that it is specific to the gateway. I tried it out on an HP LP3065 30" monitor, and the Macbook immediately offered the correct resolution. (it also worked flawlessly for 3 hours. no jumping cursors, losses of one link, or other horror problems that I had feared after reading other threads about this adapter.)

can someone from Apple comment on the XHD3000? (do Apple techies ever read these forums?)

sincerely,

/iaw

has anyone tried the xhd3000 on a mac pro (with a PCI dual-link graphics card)?

Yes. It works at the 2560x1600 resolution.

YES! I have a Mac Pro circa May 2008. That's the big boy, not a laptop. I connect my Gateway to it and get wonderful results. Full resolution, etc. [The only issue I have ever seen is the random bright red pixels that flash during certain dark video streams that have a lot of variation in them across the image. They don't stay.]

I have both the $29.00 connector and the $99.00 connector for my Unibody Macbook Pro. On the MacBook Pro with either connector, I do not have the full resolution available to see (same limits mentioned here). Both connectors behave exactly the same.

I literally disconnect my Mac Pro desktop where I get full resolution and move the cable over to the MacBook Pro where I don't get full resolution. 😟

My finger points to the MacBook Pro's configuration. Not happy...

I have gone down the road of paying for the dvi adaptor, which doesn't work with my Dell 24" monitor, then paid for the $99 dual-link adaptor, and it still doesn't work.
Sad state of affairs - how could Apple have screwed this new technology up so badly? I'm supposed to buy a new monitor now? What gives - why does it work with some displays and not others, and who would create such a thing (and not do adequate testing)?

So we can't even get full resolution with the new MBP's?

Right now i'm on my black macbook hooked up to my 30" gateway and it gets 1920x1200. I have been looking at either getting the Macbook pro or the Mac Pro. My main concern with both products was that the gateway Picture in Picture function might not work. However now I'm hearing that the MacBook pro doesn't even put out full resolution. What about the Mac Pro?

For everyone experiencing these issues, I still haven't been able to fix the issue when running OSX, but if I use bootcamp to boot in Windowx XP, my Gateway 30" monitor works perfect, with full resolution. Anyone else experience this?

just curious, can u use the picture in picture when boot it up that way?
