Aaaand MiBox 3 also works with 4k h265 10bit videos. Tested with Kodi.
Cheers.

Best part is that it comes in a "mini" (I can't recall the correct technical term!) package for small HTPC cases and is powered by the PCI-E, so no need for a separate PSU plug!Can you tell us a bit more about your test? What your cpu/motherboard is? what software you used to test? What settigns?

I tried the GT 1030 in 2 rigs: an i5 4570 Haswell, and an i7 7700k Kaby Lake. In neither case can I get jitter free playback of 4k60 HEVC 10 bit. It's even worse playing 4k60 HDR HEVC content which comes out as a slideshow.
In both cases I used VLC 3.0, forcing HDR on in Windows 10 as VLC doesn't seem able to do it. I also used MPC-BE with LAV and madVR.

Strange that 2160p60 HEVC 10 bit SDR and 2160p60 HEVC 10 bit HDR play differently? I wonder if there is some additional HDR->SDR processing overhead that causes this? In video terms - as far as HEVC playback is concerned - they are identical.

As far as I understand it, there is more decoding necessary for HDR material (see link).

I can't see where there is more decoding there for HDR replay for an HDR display than there is for SDR.
The 10 bit 2160p60 HEVC is decoded and output in the same way (same chroma upsampling) for both SDR and HDR surely? The ST.2084 HDR EOTF vs Rec.1886 SDR EOTF is a function of the screen and not part of the Kodi workflow? (Literally the only difference is the addition of some HDMI metadata I thought - that's why you can get non-HDR devices to output HDR10 video and watch it in HDR10 using either Infoframe insertion - something like an HD Fury Vertex will do that - or manually overriding your TV with static HDR10 metadata)
I keep meaning to try Infoframe insertion on my Apollo Lake set-up.
I guess GUI rendering could be an issue - but I can't believe that the AMLogic stuff is taking ST.2084 EOTF HEVC stuff to 16bit Linear Light RGB 4:4:4 for compositing the OSD GUI, then taking that back again via a ST.2084 OETF ? I'd expect the GUI to be pre-rendered in ST.2084 (or this aspect to be quietly ignored and the GUI to appear VERY BRIGHT in HDR instead)
