When I got my Seiki I basically tried all of the different Mac Window managers, most of them were immediately out of the running as they couldn't support a large enough grid to make sense (2x2 was the standard). With Divvy I could set up a 6x6 grid which is perfect as you can easily set global shortcuts to treat it as either a 3x3 grid or a 2x3 grid with your keyboard shortcuts on the Command and Numpad (see image) http://imgur.com/3E474eP This is awesome as you don't have to really 'remember' a bunch of shortcuts as the keyboard grids look just like what your screen grids are.

For Mac OS X, check out Moom (on the Mac App Store). It lets you arrange windows in various nice ways via clicks or keystrokes.

http://winsplit-revolution.com/ is a good option.

Haven't tried others because this has been simple to setup and has easy shortcuts that use cntrl+alt+keypad to move window into various spots.

I use a 39" Seiki with my MacBook, and managing windows is a relatively minor but real annoyance. I just drag and resize manually, and usually end up with overlapping windows of different sizes all over the place. I still love the display and would never go back, but it feels like I'm not using it quite as effectively as I could.

I suspect this is a gap that will be filled pretty quickly once these monitors become more common.

I use SizeUp for Mac. It lets you resize windows and move them between monitors/spaces

> Tiling window manager for OS X similar to xmonad

Presumably using a tiling window manager would solve that problem entirely. The window management in Windows/OS X is positively archaic compared to what you can get in Linux these days.
