I do need to calibrate, since I am running it in addition to my MBP screen, and they are slightly different. I tried the easy calibration route, and it didn't work. So ... I need to really dig into it. Will do so soon, but for now, it doesn't bother me too much.

Great to hear. I'm planning to get a Yamakasi Catleap or Leonidas soon. Not sure if I want a 30" 1600p or 27" 1440p.

DO DVID dual link cables always support up to 2540x1600? I have seen a couple on ebay and they state max 1920x1200.

I need to find a long (5m) one for the monitor I'll be ordering today.

According to this site, yes, it should work:

I've got a late 2009 Mac book pro and was able to get the Yamakasi Catleap Q270 working with it. I needed to purchase a dual link DVI adapter like this : http://store.apple.com/au/product/MB571Z/A/mini-displayport-to-dual-link-dvi-adapter

The adapter needs to be a specific dual link model. It is an active adapter and needs to be plugged into a USB port to get enough power to run. Once I have the adapter all plugged in, I had no problems driving the screen at its native resolution.

One thing to be aware of - the adapter from apple has some known problems. You can see them if you look up the amazon review. Every now and again you will get what appears to be 'static' or 'snow' on the screen. To solve this problem, I just unplug the adapter from the computer and plug it back in. I experience the snow issue about once every 2 weeks.

Hope this helps provide more information to anybody considering running these screens from a laptop, specifically a mac book pro.

Ok guys, after reading hundreds posts of this thread i still have some question before placing the order!

i'd very glad if someone could help me out to get out of doubts:

1.The model
I'm opting for a Shimian QH270IPSB ..yes, I want the glass!
question, is there a model with tempered glass and the speakers? it does not seem to me but maybe..

2.The video conenector
As it has already stated many times this monitor comes with just one DVI-D dual link connection. I don't have a graphic card hence i'm using the intel integrated chipset hd3000 that comes with my gigabyte mobo http://www.gigabyte.com/products/product-page.aspx?pid=3974#sp
afaik the dvi-d only support resolution up to 1900x1200 so it would not work
this adapter http://www.meritline.com/hdtv-dvi-d-dual-link-male-to-hdmi-female-converter-adapter---p-40808.aspx would not work either because of the same, HDMI support up to 1900x1200 as well and the monitor hasn't got an Ad board so it would not be able to scale. (tell me if i'm wrong!)
but it has a DisplayPort, supporting a maximum resolution of 2560x1600p
question will it work with an adapter or will it be as expensive as buying a capable graphic card supporting dual link dvi like the GeForce GT 640 ?

3.The seller
Based on others personal experiences i made up my mind with this sellers: Red-Cap, Dream-Seller, Ta_planet
I think i could live with dead/stuck pixels, malformed frames, dust underneath the glass but if there's something i can't stand is the yellow tint!!
a lot of people are experiencing low corners yellow tint issues, would somebody please post a picture to see if it's really a big issue?
question which seller do you think would take my concern in consideration most? if i ask to please check it for me, will they take care? i've read a guy called Dazog solved the problem with some screws on the back but he doesn't really explain..

Buy a cheap graphics card. Any adapter that will work with your computer will be more than $60. And would be far less reliable than a cheap graphics card.

Something like this should do it: http://www.newegg.com/Product/Product.aspx?Item=N82E16814102882



Sapphire's page confirms a dual link DVI connection: http://www.sapphiretech.com/presentation/product/product_index.aspx?psn=000101&pid=316&lid=1

DVI-D means DVI-digital, not dual link. Therefore, yes many DVI-D cables will only be able to do 1920x1200. However all dual link cables should be able to do 2560x1600.

The answer to your second question is that yes you will get a slight performance hit. But the GTX 670 and i5 are powerful enough to support it at 1440p.

Alright, 1 last thing, how common is the dead pixels issue?

What's the difference between the QH270-Lite and the regular QH270?
