Today i tested a LG 27MU67-B with the same result: No sync at 60Hz - neither with or without reduced vsync black. 50Hz was working fine. Modes are only listed up to 30Hz via xrandr. Do I need to install that KABYLAKE HUC - 2.0 Firmware maybe?!
I work for Intel Customer Support and we have seemed issues with AV Receivers, not the same issue that you are reporting but due to the large amount of different brands and models it makes it very difficult for Intel to test and validate.
Unfortunately the only recommendation that I can provide at this point is not really addressing this specific issue but just trying to make sure your system and AVR are running latest software:
- I would make sure that the system BIOS is up to date. Latest version is 0036 and it is available here: https://downloadcenter.intel.com/product/95066/Intel-NUC-Kit-NUC7i3BNH
- See if there any firmware update for the receiver, see here http://download.yamaha.com/search/product/?language=en&site=usa.yamaha.com&category_id=16446&product_id=2046003. I would consult first with Yamaha* support to make sure there are no collateral issues.
- Drivers, I would also check on latest drivers for the NUC, we have not validated Linux on this device, see the following URL for further details on validated Operating Systems: http://www.intel.com/content/www/us/en/support/boards-and-kits/intel-nuc-boards/000005628.html
- The NUC7I3BNH has been validated only with Windows 10 (64 bit). If you are running Linux I would recommend that you run the latest Kernel version and possible drivers are available here: https://01.org/
- One comment on your original post that called my attention, you said: “The HDMI-Logo at the receiver also flickers”. Does it mean that the image on the screen flickers even when the NUC is not even booting yet?
- I found a similar reference to this issue on the following website: http://www.avsforum.com/forum/90-receivers-amps-processors/2052930-official-yamaha-rx-v779-thread-2015-hdmi-2-0a-hdcp-2-2-receiver.html perhaps posting this issue on the same forum may get some help from other community members, checking with Yahama support could be helpful as well.
I hope any of this helps,
- the shipped BIOS seems already up to date
- Yamaha RX779 has the latest firmware version
- drivers of Ubuntu 16.10 have been updated via Intel Graphics Update-Tool
- regarding the flicker of HDMI logo: no, the NUC does not like to boot to more than UHD@30Hz. The flicker occurs when I manually set the refresh rate to > 30Hz. This would be a hint for sync problems imho.
So the current status is:
- direct connection to my LG UHD TV works up to 50Hz
- direct connection to my LG UHD TV using reduced blank works up to 60Hz
- connect through Yamaha Receiver to LG TV works up to 30Hz
- direct connection to LG 4K Display works up to 50Hz
Tried 4 different HDMI cables up to now - no difference.
Could this still be some software issue? I am afraid the unit is bugged/broken, since it also makes these strange noises (see my other Thread).
If you can tell me how to get the network devices running... I tried 16.04 first, but LAN and WiFi both are not supported by the kernel. Without functional network it is kind of impossible to update components. If you downloaded a functional one, plz add a link.
Edit: hang on... saw a new release was published a few days ago... will try that one via USB stick... should be fine for a test.
Actually the network devices are fine now with Ubuntu 16.04.2 LTS. But I cannot see any differences regarding the refresh rates. Exact same situation like with Ubuntu 16.10...

I am sorry to hear that running Ubuntu 16.4 didnt work, we tested it with a Yahama receiver (not the same model you have, I have to confirm) and it worked fine.
I am running out of ideas and I cannot test the exact same set up you have (we cannot test all AVRs out in the market), by any chance, did you try the dirvers and pathes available at: https://01.org/linuxgraphics/downloads/2016q4-intel-graphics-stack-recipe this is the only recomendation I have at the moment, I'll keep investigating.
Mmmh, would you mind to drop the output of
xrandr -d :0 --props
cvt 3840 2160 60
cvt --reduced 3840 2160 60
Ronny? Are u still there?
I am still around :-) sorry for not replying earlier.
I didn’t run the test I mentioned before, we have hardware available on different locations for testing and the most similar hardware we have is not in my lab so I asked someone else to test for me.
I am trying to get them to run what you requested, let me follow up again and I will get back to you.
just to let you know:
There was an update via Intel Graphics Update Tool after which UHD@60Hz now is listed within the "supported modes" list in xrandr (if TV is connected directly). Also it's 99% functional - sometimes I got a blue flashing line and audio drop outs.
Through that Yamaha receiver there is still that 24hz limit. I already talked to their support - they would like to know which receiver you have tested. Would be great if you can tell me.
Hi Mohre, I work with Ronny.
That's great to hear!
The receiver model we're using is: Yamaha RX-V381.
Hope that helps, let us know if not.
