Mac OS X

In my Mac Pro review I lamented the state of 4K display support under OS X 10.9.0. In my conclusion I wrote: "4K display compatibility under OS X is still a bit like the wild west at this point". Compatibility was pretty much only guaranteed with the ASUS/Sharp 4K displays if you cared about having a refresh rate higher than 30Hz. Even if you had the right monitor, the only really usable resolution was 3840 x 2160 - which ends up making text and UI elements a bit too small for some users. Absent were the wonderful scaling resolutions that Apple introduced with its MacBook Pro with Retina Display. Well it looks like that won't be the case for long, last night I got reports (thanks Mike!) that the latest developer build of OS X 10.9.3 includes expanded support for 4K displays, 4K/60Hz support for rMBPs and scaled resolutions below 4K.

So, OS X is essentially the only desktop operating system with proper HiDPI support, right?

I wouldn't call OS X's support proper...

...but it actually works, unlike Microsoft's.

Essentially, all it is is turning 1 pixel into 4, and then using raster scaling to non-native modes, and taking advantage of the fact that the display is higher resolution than most people can see. The "1920x1200" mode on a 15" MBP Retina is actually 3840x2400 DOWNSCALED to 2880x1800.

That said, there were ways to get higher refresh rates on big displays with older versions of OS X, although they were... convoluted (and usually involved buying SwitchResX). On OS X 10.8.5, I've run my T221 (3840x2400) as high as 33.839 Hz.

It would work on Windows, if developers weren't lazy and used logical points instead of pixels in their components.
