What's the deal with this? There are only a few monitors that have the native USB-C connection from what I can see, and not exactly cheap. I'm still using one of my Dell 2715H after selling the other, quite a popular 27 inch monitor along with my new 2017 iMac. I'm on my THIRD USB-C to displayport cable. All different brands. So far cables from Plugable and CHOETECH have both initially worked but then when they get warm after a while, start to fail. The picture breaks, starts to erratically flicker and disappears altogether or can cause weird power issues where the monitor does not even switch off anymore. The third one I'm on is the cheapest cable from Rankie, which I noticed another user in the reviews already said failed after a while with his iMac Pro. Probably just a matter of time before that fails for me too I guess. Wish the iMacs still had thunderbolt 2 / mini displayports. Those seemed a lot more reliable / better compatible with third party screens and third party cables. So is the solution forking out $50/£50 for the ONE Moshi USB-C to displayport cable that is on the Apple store or just buy a USB-C monitor? Other than this malarky, the new iMac I bought seems great.
