After seeing several 4K displays and UltraHD TVs at CES, I got excited about getting 4K displays for my nMP. I currently have two 30" ACD displays and don't really have any complaints about them. I would get 30" 4K displays (which would be a bit shorter, so I would lose a bit of physical real estate). But, the more I think about it, the more I think that maybe I'll just keep the ACDs. I worry (perhaps irrationally) that running a 4K in scaled mode would look WORSE than native resolution of the ACD-- but native 4K would make the UI too small for my eyes, even on a 30" display. Am I crazy? Anyone in my situation having similar thoughts?
