Does my NUC5i7RYH Supports 4k @ 60 Hz ? NUC7i7BNH

Hello, i've just got myself a new 4k monitor, sweet, I've connected it to my new NUC7i7BNH with an HDMI - HDMI Cable, and it ran 4K at @ Hz with no problem.

 

So i know for sure both the cable and the screen supports it.

Now going back to the older NUC5i7RYH, it only lets me run 4k @ 30 Hz through a mDP - DP cable.

 

also with the mHDMI - HDMI switch - HDMI CABLE, no success.

So i was wondering what could be the problem, does it lack the support to run at 60 Hz at all ? or am i missing something here ?

Latest drivers were installed.

thanks for the help guys!

 

Ohad.

According to the Multiple Display Setup documentation (here: https://www.intel.com/content/www/us/en/support/articles/000005571/mini-pcs.html Setting Up Multiple Displays for the Intel® NUC), in the section specific to the RY NUCs,

This tells me that the DP output is capable of outputting 4K@60Hz, but only if there is not a 4K monitor connected to the HDMI output.

I am willing to bet that the problem is the mDP-to-DP cable that you are using. I have a mDP-to-HDMI adapter that I know can support this output: https://www.amazon.com/Sabrent-DisplayPort-Thunderbolt-Adapter-Plated/dp/B01MQGPFFC Amazon.com: Sabrent 4K@60HZ Mini DisplayPort (Thunderbolt 2) to HDMI Adapter, but I have only tested it with a SY NUC. I will see if I can test it with a RY NUC tomorrow...

Hope this helps,

Thanks for the quick response!

Please update if you have any success... i'll try ordering a cable if it's working.

I was finally able to set up this experiment today. Using the same 4K@60Hz-capable mDP-to-HDMI adapter that allows me to achieve 4K@60Hz with my SY NUC, I was only able to achieve 4K@30Hz with my RY NUC.

This result does not jive with the information Intel included here: https://www.intel.com/content/www/us/en/support/articles/000005571/mini-pcs.html Setting Up Multiple Displays for the Intel® NUC. It is unclear (to me) where the problem lies. Is it a mistake on the web page? Is it a problem with this adapter? I have a query into Intel regarding this...

I will let you know when I get a response...

Hello,

 

so i got this Sabrent adapter, from mDP to HDMI, says 4k @ 60hz on it.

 

im using it with an HDMI cable that was tested to work 4k @ 60hz with my laptop and the monitor i have, but with the NUC it fail to reach 60hz, it only allows me 4k@30hz, no option for 60hz.

Maybe a direct cable mDP to DP that support 4k@60hz could work... I'm not sure yet.

 

No idea how TechHoarder got it to work. 

 

I also wonder if i even want to work on this NUC with 4K... do you guys think it runs it smoothly enough, not talking about games, just normal desktop, web browsing, youtube etc...

Ohad,

I see the same thing. The Sabrent 4K@60Hz mDP-to-HDMI adapter that I use on my SY NUC to achieve 4K@60Hz only lets me achieve 4K@30Hz on the RY NUC.

No, Jonathan, you are not!

The DP-to-HDMI IC that is used to support the HDMI connector on the RY NUCs is only HDMI 1.4b compliant. It simply does not have the bandwidth required to support 4K@60Hz. It only has the bandwidth to support 2K@60Hz or 1080p@60Hz monitors.

The only NUCs that have a DP-to-HDMI IC that is HDMI 2.0 compliant (and thus can support 4K@60Hz via their HDMI connector(s)) are the (6th gen) KY and the (7th gen) BN and DN NUCs. All other NUCs that have a chance of supporting 4K@60Hz can do so via only their mDP connector. I have confirmed that this is possible with the (6th gen) SY NUCs, but have so far failed to do so with the (5th gen) RY NUCs (and I presume that the same will occur with the MY NUCs).

This has been confirmed by the NUC Development Team.

Ohad,

The development team has verified that, if they connect a DP monitor, they can achieve full 4K@60Hz operation. Their test of an active DP-to-HDMI2.0 adapter similarly yielded only 4K@30Hz operation, however. It may be that the adapters that we are using are the problem and that others may work, but I can't say with any certainty.

I did not mean to give bad info. My monitor was in fact mini DP to DP.

That's Ok - and sorry I responded so strongly, but I wanted to make sure that no one walks away thinking that it will work. Way too often, a misstatement or a rumor will become "fact" once repeated a few times and we really don't need the extra complaints when someone discovers it is actually not true (after spending an extra US$45 on some fancy cable or dongle or something similar).

I am right now running 2 LG 4K monitors side by side on a NUC5i7RYH, one with mini DP to DP, and the other with mini HDMI to HDMI.

The main monitor is running 3840 x 2160 60p Hz

The 2nd monitor is running 3840 x 2160 30p Hz

In the end yes it can support 3840x2160@60hz with current graphics driver, BIOS and by using a custom resolution. This is working on an Alogic miniDP1.2 to HDMI 2.0 adaptor, wasn’t working until I updated the BIOS.
