Problems with NEC PA271W and MacPro

This is odd. I have just upgraded my NEC PA241W to the PA271W. Running 2008 MacPro with OS-X and the ATI 5770 graphics card. The PA271 native resolution is 2560x1440 and this is supported by the video card and is displayed among the available resolutions in the Display settings.

Unfortunately, that resolution does not actually seem to be sent to the monitor via DVI (never had an issue with PA-241 using same cable, albeit at different res). The monitor menu/info screen indicates a resolution of 1280x1440 (which incidentally doesn't even show up in the display settings). The PA271's resolution notification screen also pops up to remind me of the optimal/native resolution despite having it set as such in the display settings. Resulting image is a mess with everything appearing all jagged. I have ran a Mac software update and rebooted a couple of times to no avail.

Any input would be greatly appreciated. Thanks.
