EDIT (Feb 13, 2015): I’ve posted a review of the unit here.
The Core i3, i5 and i7 NUCs of the current and past generations have featured a Mini DisplayPort 1.2 interface that can support a 4k display at 60 frames per second resolution. However, the HDMI port that the same units have supports only 30 frames per second. Conversion of the 4k 60 fps signal from DisplayPort to HDMI 2.0 requires an active adapter and these have not been available until this day.
Most of the current 4k televisions are only equipped with a HDMI 2.0 interface and no DisplayPort so it has not been possible to plug a NUC to such a TV and enjoy 4k resolutions at 60 fps. This even if the NUC itself is technically capable of supporting 4k at 60 fps. It looks like this is about to change though.
Club 3D seems to be the first manufacturer to get their DisplayPort to HDMI 2.0 adapters on the market. Their website already features the Mini DisplayPort 1.2 to HDMI 2.0 adapter as well as the standard DisplayPort 1.2 to HDMI 2.0 adapter. For a NUC you’d like to use the former.
The specifications look promising, this is a true HDMI 2.0 capable adapter unlike some others we’ve seen before:
- Compliant to DisplayPort Specification 1.2
- Compliant to HDMI™ Specification 2.0
- Supports full link training and no link training
- 24-bit color and 4:4:4 color sampling
- Internal YCbCr 4:4:4 /4:2:2 to YCbCr 4:2:0 conversion capability
- Supports UHD resolutions up to 3840 x 2160p @ 60Hz and 1080p 3D
- Repeater for HDCP 1.3 and HDCP 2.2
- Powered by USB Port (no external power needed)
I spoke with the company this week and the first batch of the adapters is already gone, but they expect to be able to start shipping again in February. They kindly promised to send me one for review as well. I’ll definitely will be taking a look at how does it work together with the Skylake NUC so stay tuned.
