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.
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.
