Help Connect my Mid-2009 Macbook Pro to my new YAMAKASI CATLEAP Q270 SE 27" LED 2560X1440 WQHD DVI-D Dual Computer Monitor

Hi,


I am trying to connect my Mid-2009 Macbook Pro to my new YAMAKASI CATLEAP Q270 SE 27" LED 2560X1440 WQHD DVI-D Dual Computer Monitor. I am not having a lot of luck.


My machine:


OS: Mac OS X Lion 10.7.4 (11E53)


Graphics Card: NVIDIA GeForce 9400M 256 MB


Processor: 2.53 GHz Intel Core 2 Duo



I am trying to connect it using the:


Mini DisplayPort to Dual-Link DVI Adapter


DVD-D HDMI cable

Here is what is happening.


1. I connect the Mini DisplayPort to Dual-Link DVI Adapter + HDMI Cable to Monitor

2. Main monitor powers up like it is trying to display

3. Laptop Monitor displays second part of desktop

4. I can never get the Yamakasi to display a picture


Here is what I have tried:

1. Different HDMI-D cables

2. ATLONA AT-DP400 Dual Link DVI to Mini Display Port Converter

3. Zapping the P-Ram

4. Powering monitor with laptop closed

5. Forcing the system to see the second monitor


The nearest I can figure:

- The laptop does see the catsleap (it displays resolutions I can set it to)


I am completely stumped, I was hoping someone could advise me.


Thanks,


Don

Hi buddy I can see how that must be frustrating


I use a macbook pro 2011 with AMD 6750m and Yamakasi Catlea


I had a problem first using a cheap dual link DVI adapter(active but not powered? probably bs) would cause my laptop to kernal panic, so I bought the apple Dual DVI and use the dual DVI cable I received with the monitor and it works fine now.


have you tried any other computers with the screen? good to determine if its a screen problem rather than a laptop problem.




Mini Display Port->Dual DVI adapter -> Dual DVI cable -> Catleap


Thats how I have mine setup. It doesnt work if the USB cable for the Dual DVI adapter isn't plugged in as it needs to take some power from the USB.


Anyway best of luck and I hope you get this sorted!

Hey Kytarx,


I found the winning combination this weekend.


I tried:

- Apple Mini DisplayPort to Dual-Link DVI Adapter

- ATLONA AT-DP400 Dual Link DVI to Mini Display Port Converter

- Monoprice Mini DisplayPort | Thunderbolt® to HDMI®, DVI & DisplayPort Adapter


My experience:

- Altona didn't work at all, and their support claimed it would not.

- Monoprice didn't work to Dual DVI, it did work to HDMI (great price I wish it did)

- Apple Mini Displayport adapter did work, but would only work with certain USB + Display port combos.


The thing that was tripping me up was that two of the Dual DVI-D cords were bad. Once I found the working cord, it was easier to find the working adapter. The experience I did find to be a frustrating / expensive one. However, the Monitor itself is beautiful.


Hopefully this helps someone else..

Hello


I have the same Mac book pro model with the NVIDIA GeForce 9400M 256 MB. So all of you make it works using Apple Mini Display port to Dual link DVI and not by using atlona or monoporce one right? I think of buying one of that display but not sure if it will work (It should because macbook pro is able to connect to dell U2711 or apple 27" screen but the buyer website usually say their scrren won't work with laptop I think they mean normal laptop with only hdmi and single link dvi)


Thank for any advice
