For those fortunate to have a near 4k desktop monitor 3840 x 2160, here are 2 free portable apps to tune the size and placement of your windows. I am running server 2012 R2 as my main OS thanks to the tweaks at http://www.win2008workstation.com/forum/viewtopic.php?f=63&t=2499
Out of the box, you can snap a window to the far left or right of the screen to have 50/50 vertical split.
- I use AquaSnap to snap 4 windows to the top left/right, bottom left/right.
- I use WindowGrid to create a perfect square for multiple windows within one of those 4 slices of the screen.
