Has anyone used a reliable HDMI 2160p @60hz adapter/hub yet?

Even if there are adapter/hub solutions out there, I still think it sucks that Cube followed Apple’s lead by not including a dedicated HDMI out port. I’ve never had a display issue worth mentioning using an HDMI port…Type C sharing sounds like a good idea in theory – “a simple one port solution” – but in practice just looks to add more expense and hassle…and if you don’t watch what your doing power adapter-wise, might even fry your device. 8-p

I couldn’t agree with you more 🙂

I’m planning to hook the CM+ I’m getting to a 2160p display, and after a fair amount of research, this is about the only display adapter I could find that is reported to reliably output 2160p @ 60hz

Could you share your experience with us?

From what I have found, there are two main questions that needs answer before we can reliably say, whether CM+ can output 4k 60Hz:

1. What is the specification of DP alt mode of CM+? Mainly, whether it supports DP 1.4 over two DP lanes or at least over four DP lanes or whether it’s limited to DP 1.2.
2. Is there any USB-C to HDMI adapter with HDMI 2.0 output spec?

Considering the fact, that I have yet to see USB-C hub with better HDMI output then 1.4, I really doubt there are source devices supporting DP 1.4 together with USB 3.1 (even though it is theoretically possible). All of those hubs I have seen seems to use DP 1.2 which they convert to HDMI 1.4 => 4k 30Hz

So I would say, that hubs are out of the game and then what remains is to find good USB-C to HDMI adapter, which has HDMI 2.0 output. Such adapter can completely ignore USB bus and use four DP lanes over USB-C cable, so it can theoretically output 4k 60Hz even with HDR.

I am also new owner of CM+, and my USB-C accessories are on the way, so I have no experience what-so-ever. I just read a lot before I ordered, as it seems like USB-C is complete mess so far. There are so many poorly manufactured devices and so many specifications, that it is extremely easy to buy wrong devices even when you educate yourself first. For ordinary user, it is really nightmare these days…
