You need a Dual-Link adapter, assuming it has a DVI port...
Possibly a VGA adapter, not sure what rez it supports...
Hmmm, getting mixed messages from Apple here. They told me in store at the weekend that the single adaptor would work (which I am sure is wrong).
My monitor DOES have DisplayPort inputs though so would a simple "mini display port" to "display port" adaptor work like this one :
That would save me £60 and a lot of mess?
Again, Apple tell me not as the DisplayPort adaptor is only one way (why would I need bi-directional coms to drive a monitor) ? I really am begining to doubt Apples expertise as they also told me on Friday that it there was no solution to my problem AT ALL ? 3x people at Apple, 3x different answers so far.....
Be interesting to know if the DisplayPort to Displayport cable would allow me to do 2560x1440 though?
Bradri solved your problem. I had the same issue and purchased the DP to Mini DP from Amazon. I have a dell 27 inch monitor and had to go into the monitor's menu system to tell it to use the display port and it worked perfectly. You may have to do the same with yours as well.
Uncross your fingers, it will work!
Your absolutely right both of you, typing this in 2560x1440 res. Its not that sharp but I am about to reboot to hopefully sort that out.
Slightly (well actually more than slightly) concerned about how little Apple appear to know about their own products. 5 different Apple people on tech support or in store told me 5 different solutions, all wrong. Several told me the £8 cable wouldn't work and 2 told me the £70 dual DVI cable would (which has loads of issues according to reviews).
My 27" Dell arrived yesterday. I connected with mini display port to display port. By default the monitor was set to receive a DPI signals. Changed that and the monitor seems to work great at full resolution. The MDP to DP cable is considerably less expensive and more elegant than double DPI. This setup looks very sharp to my old eyes.
SkiesNPies, considering similar (except cheaper display port monitor), did it get sharp enough on reboot? Or did you go another solution in end? Likewise saw DVI dual cable dodgy reviews and fighting shy of that solution. Thanks, Tom
I just got a Mini-DisplayPort to DisplayPort cable for cheap ($5 USD), and it technically solved the problem with my new 2560-wide monitor, but it looked so bad that I went back to 1920 with the DVI cable. It looked like a badly interpreted analog signal or something, not a digital signal. Looked decent on images, but terrible on text, was giving me a headache.
I used my iPad to take pictures of some pixels. (Yes, this is Visual Basic code, one works with the code one is given...)
This is with the DisplayPort cable - notice the lightening above the letters, against the green background, and the blurring on some horizontal lines, such as the capital D's. Also there's a sense that the green from the green text on line 12 is blurring generally - nearby pixels pick up a green glow. [NOTE: These are automatically scaled - you can see the original image if you click on it.]
Here's with the DVI cable - only 1920, but much prettier text:
Maybe I'm spoiled by Retina displays, but there's no way I can put up with that stuff on top. (The HDMI output from my MacBook Pro also works at 2560, but looks even worse.) I've sprung for Apple's $100 USD "Dual Link" adapter; it'll either work well, or I'll send it back and make do with 1920.
If anyone has an idea about getting better quality for less - maybe there's a slightly better Mini-DP to DP cable out there that works better? I'd love to know about it.

Hi Appollo Grace!
I understand the dislike of the text sometimes on the full scale res. I have noticed sometimes a blue/red/green tinge to edge of text, which can be slightly frustrating... but overall I adore the 2560x1440 and would never go back! I've got a BenQ BL2710 at work, which is significantly better text wise than my Viewsonic VP2700 at home, but the you don't need Dual-link DVI. Mini display port to display port is what you are after... The DGM monitor is also better at full res (just popped over to look at a colleagues) than VP2700 on text (displayport too).
Spend a few more quid on a cable if you want, but it shouldn't matter too much. If you're getting signal it is digital and it's just a reflection of the monitor's abilities sadly.
Grace & peace to you!
