Are HiDPI resolutions ultimately dependent on the OS? 'cause SwitchResX lets you put in custom resolutions that don't show up as HiDPI. Also, I'm not disappointed. I just have a 16:10 monitor in a 16:9 world. And I haven't seen a monitor that looks as good as this one, regardless of resolution. Also also, re: the startup progress bar, what I meant is that being able to start up from the recovery partition is the only reason I care; I can deal with using the control panel to select a different startup disk once every 14 months when I need to do that.
