27" Screen resolution?

[DesignFusion]

Hi guys, hoping someone can help. I have a NEC PA271W (2560x1440) screen plugged into a new macbook pro 15" Via a DVI to MiniDisplay/Thunderbolt. However I'm only getting 1920 x 1080 res?

Any ideas? I have tried looking for a driver but couldn't find anything. I have also tried resetting the NVRAM with no luck.

Would appreciate any ideas

guess you use single-link DVI. What you need is a miniDisplayPort/Thunderbolt to Dual-link DVI adater
something like this

best would of course be to just use the displayport on the display (i think the NEC has one)

Single-link DVI (which is what you get with the standard adapter) won't hack 2560x1440 resolution.

However, the monitor you mention has a DisplayPort input, so something like this should work:

...at a fraction of the price of a dual-link DVI adapter.

Some monitor/mac combinations have a problem with Macs & displayport or HDMI resulting in a blurred, low-resolution-looking screen even when the resolution is correctly set - if you're unlucky, there's a fix for that here.
