2560 x 1600 without the Dual Link Wire

I just this second hooked up my brand new 30" monitor and it is at 2560 x 1600 and I have no dual link wire connected at all.
I can't even plug in the Firewire because my Mac Pro Tower had square Firewire plug and not the angled ones this came with.
It came on and I was like man everything looks so tiny. I went into displays and blam there it was at 2560 x 1600.
I thought the only way to get this resolution was to have the Dual Link.
Is it only the laptops that need this wire to get this 2560 x 1600 resolution?
I can fit 3 web pages fully open next to each other. I put it to 1920 and it looked way different.
I am not a new comer to these types of things but all I kept reading was how I needed the Dual Link wire but just using the single DVI wire that comes attached to the monitor it is at the 2560 x 1600.
Someone please weigh in.
Thanks

Well after searching and stumbling upon a Vid car with a Dual Link DVI port that could do the 2560x1600 with no Daul Link wire I decided to investigate my own card.
My Mac pro Tower is new and came with a NVIDIA GeForce GT 120.
Well this description tells the story of why I don't need the cord.
NVIDIA GeForce GT 120
PCI Express 2.0 Video Card for 2009 Mac Pro with 512MB GDDR3 Memory, 1 Mini DisplayPort, and 1 Dual-link DVI Port
Now it makes sense. I'm dumb I guess.
It is too bad all those with the wire problems can't just kick in a few dollars and get a video card for your computer that comes this way.
Of course I don't know if that is even possible so don't kill me on that statement.
Anyone else who didn't know why I was getting the 2560x1600 that is the reason.

Exactly how does the Dual Link plug into the 30"

Ok I keep seeing pix of this plug yet I can't get a grip in how it works.
I am assuming it works with the DVI plug that comes with the 30"
If anyone has a photo of the way it is connected I would appreciate a link. I just want to see it. Can't explain why.
I have also still been only able to find mostly complaints about the plug. Is it really that bad. I will never get the full resolution without one but it seems not worth the trouble.
Anyone with experience or knows my options would be nice to hear from as well.
Lastly this.
I if hook this up without the dual I can still use my 2nd monitor but if I ever use a dual-link will I need a 2nd video card to keep my 2nd monitor running.
I assume yes using common sense but I haven't seen the setup.
Thanks a lot

Well that was the perfect answer. I never read that about the plug but now it makes sense why it looks the way it does in the pix.
I always thought it had 2 ins and 1 out. I mean it does but just in one plug.
I would still like to know if they are still junk. Do they still flicker and work bad.
30" in pointless without the resolution.
I use a 32" but it only goes to 1378 because it is a 720P and everything still gets in the way so that is why I also have my 24" running.
I do a lot of multiple tasks and like to look at one thing while doing another. Putting my word docs to the left and copying and pasting into quark but I like to see the formatting without having to look under the files to see what is bold, etc.
Well until I know about the plug there is NO WAY I am spending $100 for junk. I know Apple will say they are fine and I am sure there are people who's work perfect.

ATI 9600 Pro Mac & PC Ed. - Which is the Dual Link DVI Port?

I just bought an ATI Radeon 9600 Pro Mac & PC edition Video Card:
http://www.ati.com/products/radeon9600/radeon9600propcmac/index.html
This card features 2 DVI ports - one of them dual link.
Maybe I'm just blind, but I've been looking around everywhere trying to figure out which DVI port is the dual link. Does anyone know?
Any help will be appreciated.
PowerMac G5 dual 1.8, TiBook 550, Compaq V2000 1.68 Turion Mac OS X (10.4.5) G5-160+120gb,1.5gb,4xSD | PBook-20gb,768mb,Combo | V2000-80,512,8xDL+Lightscribe

There is a small "1" stamped in the sheet metal next to the single link DVI connector, and a small "2" next to the dual link DVI connector. The single link is closer to the motherboard.
There should be a PDF Users Guide on the Mac CD that came with the board. Page 17 shows the connectors.

Is anyone having stuttering problems on the ati 5870 with the mini dislplayport connected monitor when you turn off the display connected to the Dual-link DVI port?

hey i have a ATI 5870 and when ever i turn the monitor connected to the dual_link DVI port the display connected to one of the mini display port shutters with everything on the screen Video, Mouse movement ect, any ideas ?

hey i have a ATI 5870 and when ever i turn the monitor connected to the dual_link DVI port the display connected to one of the mini display port shutters with everything on the screen Video, Mouse movement ect, any ideas ?
Not sure what you are trying to do. I interpret what you are saying is that you have a monitor connected to the DVI port and another to the mini displayport (mDP). Are you physically trying to turn the one connected to the DVI port off (and on) causing the one on the mDP port to "shutter"? If so, take a look at SwitchResX. It will allow you to programmatically turn monitors on or off. Maybe that will cure the problem.
Of course if I am misinterpreting what you are saying ignore this post.

Cinema 30" - What is the Dual Link DVI Cable Length?

Planning my install, but can't find out how long the DVI cable is in length on the 30" Cinema display.
Anyone know or can measure their cable?
Thanks!
Dave

Cable is 2m. Not sure what the +/- tolerance is, but figure 5cm. And the breakout ends for USB, etc. are a little bit longer, just enough to allow them to reach their mating ports on a system.

Display port Dual link DVI to Gateway XHD3000

The *displayport to dual-link dvi adapter* I bought doesn't seem to work with resolutions > 1920x1200. My Gateway XHD3000 monitor supports upto 2560x1600 but I can't set this resolution in the system preferences. I have set my power setting to "+Better Performance+" hoping the other GPU would be used but still the same lower resolution.
I'm using the Dual-link cable that came with my monitor.
I actually have 2 systems exactly the same with this problem.

Here is what the Gateway Tech support had to say. *Very helpful*....punt!

Dear Emmett Bearden,
Thank you for contacting Gateway. I apologize for the inconvenience that you have experienced. If you cannot set the monitor resolution greater than 1920 x 1200 or up to 2560 x 1600, this may occur if your MacBook Pro does not support dual-DVI output, does not support this kind of ultra-high resolution, or does not have the latest video driver. I suggest you please first contact Apple's technical support, to inquire if the MacBook Pro supports this resolution, or if they have a workaround for this problem.
Respectfully,
Gateway Online Technical Support
Customer (Emmett Bearden) - 01/07/2009 12:26 PM
Using my Apple MacBook Pro I'm unable to display a resolution greater that 1920x1200. I bought this monitor for the 2560x1600 resolution. My connection is a dual dvi using the cable that came with the monitor.

Switching between Dell 4K display and Apple Mini DisplayPort To Dual-Link DVI Adapter

Hi All,
I've recently upgraded my home setup to a Dell 4K display (Dell P2815Q), which since the 10.9.3 update work as expected.
However the downside is that my office setup uses a Mini displayport to Dual-Link DVI adapter (Firmware version 1.03) and a Dell 30" display (2560x1600), which will not work without a reboot after using the 4K display. If I use the 4K display after using the Dual-Link DVI adapter it works fine.
Is this a know issue ? If not, I'm happy to provide some more diagnostic information to help resolve the issue.

http://www.everymac.com/ says:
*This model supports a simultaneous maximum resolution up to 2560x1600 on two external displays via Thunderbolt. Alternately, it can support a single display up to 2560x1600 via Thunderbolt and a single 1080p display at up to 60 Hz, 3840x2160 at 30 Hz, or 4096x2160 at 24 Hz via HDMI.
DVI is not mentioned at all. You probably need to connect to the display via HDMI to get the 4096x2160 resolution.

Single Link DVI-I to Dual Link DVI-D?!!

I have a (G1)Power Mac G5 with a ATI Radeon 9800 Pro with a Single Link DVI-I connecter, and my LG 19'' LCD has a Dual Link DVI-D connecter. What DVI cable do I need? I heard the newer Dual Link DVI-D cable will work with the older Single Link DVI-I. if it does, how does this work? DVI-I and DVI-D has differant pin slots. Please help!

The display is probably single-link DVD unless it is more than 1920 X 1200. The DVI plug may have all the pins, but the dual-link pins are probably not connected to any wires. The Graphics board uses DVI-I which include digital and analog. It can be used with DVI-D cables which don't use the analog signals.

Jittery mouse with SINGLE link DVI adaptor!! Not Dual-link

Hello All,
I've found the Dual-link DVI adapter threads regarding this known issue but I'm now experiencing this with _not just one but 2 Single Link DVI_ adapters and my 24" Benq display.
I bought these 2 adapters the day I bought my laptop (mid-december) and was using one non stop for several months without a single issue and 2 days ago, suddenly my mouse is constantly jumping when connected to an external monitor. A reboot will not alleviate the problem, only when I disconnect the mini dp to DVI adapter does the mouse start behaving correctly. It happened before and after I upgraded to the new iTunes 8.1 and iLife support update. Everything else is up to date on my system...
I've tried:
-Zap Pram
-Remove all USB devices but mouse/keyboard
-Many many reboots
-Switched from performance to better battery mode on the display settings
-Uninstalled completely (and properly) iStat menu
-Using 3 different mice
-Used a brand new mini-dp to single link DVI that I had purchased for my laptop bag and never used
So I'm back to using my laptop screen in front of a dark 24" monitor since I can't really work efficiently with a constantly jumping mouse. I've not seen anyone else experiencing this on a single link adapter... Anybody else???
Thanks!

I have found a possible solution to your issues. It worked for me. I am using the midi Display to DVI.
My issue was that I started getting the mouse and video lag when the external monitor was plugged in. I had no issues in the past, it just started to happen. I thought it was a XP update so when I booted back to XP there was no lag. It was strange. I had called support and they cleared my memory but that didn't work. So when they told me it was hardware issues I didn't really believe it. Especially when it was working ok in XP but not in OSX.
So to make a long enough story short, the thread I found suggested to plug your monitor in another location than the Mac is plugged into. Like a surge bar. I had both plugged into a surge protector so I plugged the monitor directly in the wall and what do you know, the lag issues stopped.
Sounds strange but why it work, Who the frak knows. I am just glad it fixed this issue. Was driving me nuts.

MiniDVI with Dual Link won't display after restart

I have a bizarre problem I can't find and hope to get some help.
I have a brand new late 2009 Mac Mini 2.53Ghz with 4Ghz of RAM running OSX 10.6.1 and Vista Ultimate 32bit via Bootcamp 3.0 drivers.
I have the Mini DVI Dual Link adapter so I can use my 30" Apple Display.
When I run Vista Ultimate, the display works fine, unless I run a restart to reboot Windows. When that happens, the mini seems to cycle just fine, but there is no video on the monitor. Sound works fine, and nothing seems amiss with the Mac Mini except that there is no video.
If I then cut the power to the Mac Mini (not a nice thing to do!), when power comes back it reboots and the display works fine with full video.
This must be some foolishness associated with the use of the Mini DVI output into the Mini DVI Dual Link adapter, but there is no other choice in the matter with the latest Mini.
Any suggestions?

I purchased the same computer: 2009 Nov 16, Mac Mini, 4GB RAM.
Computer runs great with the dual-link video adapter connected to my 30" Apple display.
I installed Boot Camp 3.0, Windows 7 32 bit (Business).
The video driver (by default is a 2006 Microsoft version) and only support a max resolution of 1600 x 1000 (aprox - sorry not in front of it at the moment).
I downloaded and installed the latest Windows 7 driver from nvidia to hopefully correct the problem, but matters worsened, with the max resolution dropping to 800x600. I backed out the latest Nvidia driver and am back to the Windows default - which is OK, but not nearly the resolution that I paid for and presently enjoy with MAX OS X.
Does anyone have a solution?
Thanks

Mini Displayport to Dual-Link DVI Issues on 30" Cinema Display

I know this problem has been around for a while, and that there are several other discussion on it, but my goal here is to point out that even in mid-2011, this issue remains.
Here's my configuration:
30" Cinema Display
Dual-link MDP to DVI adapter with 1.03 firmware (purchased August 2011 from an Apple Store)
New-ish MacBook Pro (purchased December 2010) with Mini Displayport
Symptoms:
On dark areas of the screen, DVI noise appears (horizontal flickers of light coming and going at random)
Attempted Fixes:
Unplugging the display and plugging it back in to the computer (failed)
Restarting the computer (failed)
Tightening the connections on the Dual-Link DVI adapter (failed)
Sleeping the display and awaking it (failed)
Some suggest getting a new 27" Cinema Display with native Mini Displayport/Thunderbolt support. I actually have one, but I cannot tolerate the glare on the glossy displays, so I'm "downgrading" to a 30" Cinema Display.
Is there any remaining hope for this issue?

I still cannot understand why you would return everything... Ultimately you want this computer right? Once the bugs on the adapter are fixed are you gonna go back and re-buy it?
Seems like a lot of time spent out of spite and not for good reason. Me, this is the best Mac I've ever owned (and I've owned many. no, really.) and I'm happy to wait for this adapter w/ this machine in stead of going back to my other box.
I observed a similar client of mine w/ an iPhone... after the first week, he didn't like the keyboard and a few other things, so he took it back and went back to using his Blackberry -only to dump the Blackberry again for the iPhone, because he realized that the iPhone still did more things better than the Blackberry.

Mini Display Port to Dual Link DVI Does Not Work Right

Somebody said here that this was an isolated problem. Well, I just got my new MacBook Pro 15", used the adapter to hook to the 30" Dell monitor, and it works a few minutes, then the screen distorts.
Count me among the isolated problems- it is beginning not to look isolated.
Now, do I wait on Apple to fix the problem, or do I return the MacBook Pro while still in the return period?

Hi, Matt, and welcome to Apple Discussions.
The Matrox Support only told me that the new MacBook Pro with Mini Display Port is not supported, but as it's working for 2x1680x1050 with the Dual-Link DVI adapter, I was wondering if the Mini Display Port to Dual-Link DVI Adapter could be the problem.
I suspect that what Matrox Support meant when they said "not supported" was, in fact, "not supported": i.e., they've tried it and it doesn't work satisfactorily. You've tried it too, and found that to be true. Now you just need to come to terms with the fact. Matrox is quite open about it; it's not a secret.

No Video from Mini-DisplayPort or DVI, only Dual-Link DVI

Just got my new Mac Pro 6-Core delivered. Out of the box, there were problems. I have a Dell 27" monitor that takes Dual-Link DVI, DisplayPort, or HDMI and a Dell 22" monitor that takes DVI, VGA, or HDMI. I am using a DisplayPort to Mini-DisplayPort cable to connect my 27" monitor to the Mac Pro and a DVI cable for my 22" monitor. I have the ATI 5870 graphics card installed OEM.
The problem is that the graphics card appears to not be switching to Mini-DisplayPort or DVI for output. It only works when I plug in a Dual-Link DVI cable to my 27" monitor. At that point, I get a video feed on my screen on a hard boot. At this point, I can then plug in my Mini-DisplayPort cable to my Mac Pro and unplug the Dual-Link DVI cable, and it switches video feeds perfectly. The problem then is that when I restart the computer, or power off and power on, the problem starts all over again. I HAVE to boot using the Dual-Link DVI cable for anything to work.
Ideas? Called AppleCare, waiting on engineering to see what they have to say. All the cables work perfectly when I plug them into my MacBook Pro (Late 2008). I am stumped.

I seem to be having similar problems. I bought the same system (6-core Westmere with the 5870 graphic card installed OEM) last month and I seem to be having problems running two Dell monitors which I know to be perfectly fine.
For the past month, I've been using a 24" Dell U2410 monitor with my Mac Pro using a DVI cable. Absolutely no problems at all. I then purchased another 24" Dell U2410 with the intention of running with dual displays. To prepare for this, I bought two mini-DisplayPort to DisplayPort cables from Monoprice. When I finally received the second display, I turned off the computer, hooked up both monitors through DisplayPort using the two mini-DisplayPort connections on the graphics card and turned on the system. I got two black screens. I tried to use keyboard commands to bring up the shutdown dialog box but it wasn't working. So I was forced to do a hard shutdown by holding down the power button for 10 seconds.
I went through a series of combinations of power cycles for the displays and computer and still two black screens. Finally, I went back to square one, a single display through a DVI cable. Again, a black screen. At this point, I disconnected the display from the computer. Power cycled the display (this initiates the self-test for the Dell display), hooked it up to the Mac Pro, turned it on, and it worked. I had one working display. Then I plugged in the second display using the mini-DisplayPort to Display port cable and that worked also. Finally, two working displays. For some reason, the Mac Pro recognized the display using the DisplayPort as the primary monitor. I rebooted the Mac Pro and the monitors continued to work properly. I booted into Windows 7 and again, no problems. I went back to OS X and used the computer for the night. When I was done, it put it to sleep.
This morning, when I tried to wake it up, same problems. I had to go through a series of power cycles and cable swapping to finally get a single screen to work.
I went through some of the troubleshooting documents here in the Support area and found this one:
http://support.apple.com/kb/HT4279
I am going to pick up the Apple mini-DisplayPort to DVI adapter and try running the display as two DVI monitors. Hopefully this will fix those problems. If the AppleCare engineer is able to give you anymore information, please let us know. This is a worrisome issue.

Mini Display Port to Dual-Link DVI Adapter: No image with 3840x1200

Hi!
I ordered the Mini Display Port to Dual-Link DVI Adapter regardless of the many complaints that it's not working in order to connect my new MacBook Pro to my Matrox TripleHead2Go. This Graphics Expansion Module normally allows to use two 1920x1200 monitors when connected to Dual-Link DVI (3840x1200). It works fine on my old MacBook Pro (with Dual-Link DVI output), but with my new MacBook Pro the first monitor just turns black and the second tells "Out of Range" when using the Mini Display Port to Dual-Link DVI adapter.
When I am reducing the resolution to 3360x1050 (2x1680x1050) it works, but this is not the native resolution of my two 24'' monitors and therefore is useless.
The Matrox Support only told me that the new MacBook Pro with Mini Display Port is not supported, but as it's working for 2x1680x1050 with the Dual-Link DVI adapter, I was wondering if the Mini Display Port to Dual-Link DVI Adapter could be the problem.
Any input welcome.
Thank you in advance.
Cheers,
Matthias

ACD 30" Dual Link DVI and MacBook Pro Unibody

I have the following configuration:
ACD 30" Dual Link DVI and MacBook Pro Unibody
I am exhibiting some intermittent problems with the 30" display not coming up when I reboot for example and here are some more:
1. MacBook Pro not in clam-shell mode and restart equals 30" display not turning on
2. When in Snow Leopard and I have the MacBook Pro running in clam-shell mode and I open the display on the MacBook Pro it remains black.
3. When waking the MacBook Pro from sleeping (MacBook Pro in clam-shell) the 30" ACD is "grainy" and the display is not usable and it requires a reboot to solve the problem.
Any help? In addition are there any other displays using mini-display port to mini display port technology?
What about a different monitor; will I still have to use the Dual Link DVI adapter to drive a display with higher than 1920x1200 resolution?
Are there adapters to go from mini-display port to display port?
Thanks,
Mike

Just came across your post and i have a couple of suggestions ive noticed with the Dual-Link to Mini-DP with the same configuration.
When working in clamshell mode for example, the 30" will become the MAIN/Default display...So if you open your macbookpro while the 30" is on and the system is running, the screen will remain black because it is in closed mode; basically meaning there is no signal to be sent.
so if you want the display to show up, either restart or put into sleep mode, then wake the system WITH THE LID OPEN.
As for the grainy/static artifacts, its beena reported issue since day 1, not sure waht the fix or issue may be with it but heres a resolution.
Press; SHIFT CONTROL EJECT-KEY all at once, this will disable signal to the monitor, but not shut off the machine...then use your mouse or press a key on the keyboard to wake the display and the grainyness should disappear.
