Now that 4k monitors are dipping below $400, buying one for my desktop computer setup seems like a no-brainer. Problem is, I want to drive it at a logical resolution of 1440p. 1080p just doesn't give me enough screen real estate for my work, and native 4k resolution would make me go blind. So I want 1440p. This is ridiculously easy with Windows, just set the display scaling slider to 150% and call it a day. What are my options with a Mac? I currently have a 2012 Mac Mini and that's definitely a non-starter, since I can't even get it to display 1080p high-DPI on my current 1440p monitor. I would be willing to buy a more recent Mini but it seems like people have trouble getting the 2014 Minis to drive a 4k display at anything over 30Hz, much less run 1440p high-DPI. I guess recent MacBooks would be able to do this, but if I'm considering a ~$1500 laptop plus ~$400 for a new 4k display, it would be cheaper to just buy a new 5k iMac at that point. Is anybody else annoyed that this seems to be a completely solved problem with Windows and tragically difficult with OS X?
