With the release of Lion, users can now see some of the groundwork that Apple has laid down in OS X for ultra high resolution displays.



From MacRumors:

For those who have downloaded Apple's Xcode for Lion, you can enable "HiDPI" mode in the Quartz Debug application found in the Developer directory. Once enabled, OS X's Displays control panel offers additional 1/4 (and lower) resolution sizes as shown here on a 30" Cinema Display with a native resolution of 2560x1600:

Unfortunately, there's not much to see yet. The 1280x800 HiDPI resolution shown here represents exactly 1/4 of the area of the native resolution of the 30" Cinema Display and simply offers you a zoomed in view on present day monitors.
