I'm monitor shopping for the 2012 Mini I just got from ebay. There are a lot of cases where a 27" 4K monitor is not much more or even cheaper than a 27" 1440p monitor....especially with the Dell 4K on sale. I'd rather buy a better monitor now knowing that 1440 is soon to be outdated and knowing that I'll be upgrading the computer sooner or later and would rather just have the monitor for the longer haul. So what is the max the mini puts out at 60hz? 2560x1440 or 2560x1600? Can I run either of those resolutions on the 4K without it scaling poorly? I'm looking at the Dell p2715q. Thanks!
