Hello nshaver ,
Sorry, Intel has release only Windows 10, 64 bit version of the Firmware Upgrade Tool. The Linux is not on the list supported O.S. for your NUC: Supported Operating Systems for Intel® NUC Products
Thank you very much to lw1948 for the comments posted above.
nshaver: Thank you very much for joining the Intel® NUC communities.
Just to let you know, regarding the 4K at 60Hz resolution, we do have a web site for Linux where you might be able to get different graphics drivers to install them in order to try to fix this problem:
Also, the link below is for the Linux forums, where you will be able to get further peer’s assistance and suggestions on this matter:
Any further questions, please let me know.
Thanks for the suggestions. I'm pretty sure that Ubuntu 17.05 already has very recent Intel graphics drivers. Rather than adventuring into installing drivers outside the Ubuntu repositories, I'm going to hold off. I have ordered a thunderbolt-to-HDMI adapter, and I've seen several people commenting in various places that it allowed them to get 4k 60hz when the onboard HDMI port didn't. I'm hoping that might be the case for me too. If so, problem solved. If not, I'll consider diving in deeper with third-party repositories and drivers.
I went ahead and installed Windows 10 onto a USB drive, booted to it, installed the basic NUC Windows 10 drivers, and 4k 60hz works fine in Windows. So, it's not my TV, not my cable, not my NUC graphics firmware. It's something with Linux that's preventing 4k 60hz from working. It's good to at least rule out hardware issues. I'll now move on to researching the Linux driver issue.
nshaver: You are welcome. Thank you very much for sharing those details in our communities, we really appreciate that.
Yes, to researching the Linux driver issue will be the best thing to do now, hopefully you will be able to get additional details from the Ubuntu forums as well.
Any questions, please let me know.
If you want to update firmware (as you have mentioned in your original question), the Linux driver will not substitute it. Intel has release a firmware update that updates the HDMI 2.0. If your NUC has this version of firmware (ver. 1.66), you don't need this update.
I finally got 4k 60hz working in Linux. It didn't require installing any new firmware on my NUC. I did update the bios firmware to the latest version (0046). I'm not sure if that brings in the latest graphics firmware or not. Here's what I've wound up as my solution in case anyone else wanders across this post needing similar help.
1. updated bios to 0046, rebooted into bios setup, F9 (set all settings to default), advanced screens, set both video memory options to 512
2. I rounded up some modelines that work for my TV (Vizio D50u)
3. created new modeline using xrandr:
xrandr --newmode "4096x2160_60" 556.730 4096 4104 4136 4176 2160 2208 2216 2222 +HSync -VSync
4. add mode to the NUC port that my monitor is using (DP-2, could be DP-1 if using HDMI):
xrandr --addmode DP-2 4096x2160_60
5. use new mode:
xrandr --output DP-2 --mode 4096x2160_60
I'm currently using it via a USBC->HDMI2 cable that I bought on Amazon - Amazon.com: Plugable USB-C to HDMI 2.0 Cable (6'/1.8m) for 2016 MacBook Pro, Dell XPS 13 & 15, Thunderbolt 3 & More (Sup…
I think it would work fine though via the built-in HDMI2 port. If that's what's needed, all of the "DP-2" above should be replaced with "DP-1"
My HDMI2 port is currently running 1080P on a second monitor.
Things are working perfectly now, and I'm very very happy with my NUC purchase.
nshaver: Thank you very much for sharing that information is our communities, we really appreciate that and I am sure it will be very helpful for all the peers viewing this thread.
Perfect, excellent, it is great to hear that the NUC is working perfectly now.
