How well does windows support subdividing the screen? I know in normal monitors it can do left, right, top, and bottom halves and quarters but for something like that I'd be looking at thirds. Also video game support would be crucial.
> But I also typically only share single windows, not my screen
I often have to share a desktop (screen) to show dialogs, select options, etc that don't show up in tab or window shares. Or if I'm moving between code and browser.
