I don't think I want to spend the money on a 24" 4K since I have a lower res 24". I don't fully understand all this scaling business. Is there a 27" monitor that is recommended for high res or 4K? I'm spoiled, I don't want to see pixels anymore but also don't want to hold up a magnifying glass to read anything. Like, what iMac type 27" type display looks as good with a mini?
