Hey all, I'm thinking of getting a 27'' iMac. Can anyone suggest a good second monitor? I'd love to get the Apple thunderbolt display but it's terribly outdated. I'd like a 4k or 5k monitor that looks sort of similar to the iMac display. I looked at some of the Dell displays but they look completely different. Although if this isn't possible that's not a deal breaker. Mainly I want a high quality monitor as good as the iMac 5k display. Any suggestions? Thanks!
