    I was wondering what folks are using as an external monitor and if there have been issues running a second screen with iMac 5k?

    I have a DELL U2410 24" monitor. I am having issues getting it recognized overtime I reboot. I have remove the display port to dvi adaptor and re-insert it two to three times in the thunderbolt port for it to be recognized. Once it starts working, it's fine.

    been running with a cheap 1080p DVI monitor since the beginning. No problems at all, except by comparison, the external one looks a bit nasty.

    I ran a Dell 5K monitor before I had to return it (not because of the monitor). Ran perfectly well.

    Instead of creating my own thread on a very similar topic....

    I also have a 5k iMac. Can I connect a Dell U2715H via a Thunderbolt (Mini Display?) connection? I expect I can....but there's a catch.

    I also want to be able to connect up another device to that Dell monitor and switch between the two inputs. The monitor comes with a mini DisplayPort and a separate Display Port connection (and the manual suggests I can switch between the two inputs - so I'll connect up my iMac to the MiniDisplayport and use the separate Display Port for the other device.

    If I'm reading it correctly I should have few problems but I'd rather get advice first.

    6 months in (just about) with my Mac journey and still enjoying it! :)
