How well do 2015 iMacs display 4K content?

    Wondering how the current i5 or i7 iMacs perform with 4K or even full screening 1080/60 content - any issues with YouTube? Netflix support? Other high def rental services?

    One of the benefits I see with the new kaby lake CPU (to be used in next-gen iMacs) is the native encoding/decoding of more common 4K video codecs. So without taxing the CPU, it should become much easier for computers to display high def content, less buffering, framerate stuttering, fans blowing, etc. (If that is a factor at all.)

    What's been your experience? Works well or is this a feature worth holding out for?

    Dunno about the ones that don't have a dGPU, but for the ones that have a dedicated GPU, at the very least mine, it works very well. With 4k YouTube, fan spins at around 1400RPM, which is a nearly unnoticeable increase from the idle 1200RPM. 4K Netflix, as far as I know, isn't an option though as a result of how they do copyright protection. I believe that as of yet, no PC/Mac supports that, and it will require Kaby Lake when it does get supported (Or maybe can be worked around with a GPU). Aside from that 4k and 5k content works fine.

    Yeah, no 4k netflix is just a joke, even if it's not apple's fault.
