I have this: iMac (Retina 5K, 27-inch, Late 2015) and this monitor here


I connected it via thunderbolt and https://www.amazon.it/gp/product/B06WWPZRFH/ref=oh_aui_detailpage_o02_s00?ie=UTF8&psc=1

the monitor works but I'd like to know how I could reach 60Hz, for now it only goes at 30Hz.

any idea? thanks

According to the description of the adapter you linked on Amazon, the adapter only supports 4K at 30Hz. You would need a different adapter to reach 60Hz, like this one: 4k 60Hz mDP-HDMI adapter.

  • but it says: Transmits both audio and video from computer or tablet to HDTV display; Supports video resolutions up to 3840x2160 (Ultra HD) at 60 Hz and flawless audio pass-thru for uncompressed digital 7.1, 5.1 or 2 channels.

    @sathia It does say that in the general description at the top, but if you scroll down to the bottom to the more in-depth description, it says: It can support displays of up to 3840x2160 @ 30 Hz HDTV or 4096x2160 @ 24 Hz PC graphics and is ideal for your office, home entertainment display, conference rooms, and more.

  • @sathia I would try the one I linked in my answer (it looks less sketchy - and try to return the other one to Amazon, if possible).
