Did you flash to the latest BIOS? Have you tried a different HDMI cable?
Thanks for your reply, the NUC7i3BNH already have the latest BIOS (bnkbl357.86a.0031.2016.1206.1405). I also purchased a brand new HDMI cable and nothing changed.
I've had similar issues with some NUCs and my older Proscan TV, but they tended to be cable issues. This is a newer model thought, so I haven't tested one. What version of the graphics driver are you running?
I've updated all the drivers to the latest version using the intel driver updating software. The cable works absolutely fine with all devices except the NUC.
The NUCs have had a long history of problems with UHD TVs. The current generation of NUCs is supposed to be able to work with these TVs though thanks to their HDMI 2.0 port. And there are adapters available for older models of NUC.
Finding clear and conclusive solutions to using current-generation NUCs with UHD TVs is no easy task. I did pick out the following suggestions from extensive research on the subject though.
1. If you have more than one HDMI 2.0 connector on your TV, try it with a different connector. Some people found that whilst their NUC did not work with HDMI connector 1 on the TV, it worked with HDMI connector 3.
2. Using audio pass-through caused one user a black screen, similar to the one that you experienced..
Yes that's precisely why I waited for the new Kaby Lake version, to quickly setup a HTPC capable of 4k without hassle. Seemed like a nice upgrade from my $35 raspberry pi that never had problems to connect to the TV.
With the NUC I have tried all 3 HDMI ports on the TV. I get best results on HDMI 1, but again it only works with the hot swap.
I didn't try the DisplayPort because I don't have the adapter but thanks for the tip. I'll wait for a reply from Intel otherwise I guess I'll just return it.
Ok I was investigating this further and here is what I found on the REGEDIT:
The NUC recognises and store the EDID information for the Philips TV under:
For the Samsung TV however it fails and you can see there is no Device Parameters key. The Default Monitor also has a key BAD_EDID
Now it seems that there is a way for Overriding Monitor EDIDs with an INF (Windows Drivers) , however I lack the knowledge to try this solution. Can anyone help me with this?
The hot swap reminds me of an issue I had a couple of years ago with connecting a PC via HDMI to a big 42" Phillips widescreen plasma TV. You had to turn the TV on first and then turn the PC on second, otherwise the TV could not detect the PC's video signal and display the picture if you turned the PC on first and the TV second.
I hope someone can help you with the EDIDs. Good luck!
Hey Leonardo, that is really crazy and unfortunately as Marty Grover has said, these kinds of issues have been prevelant for a while.
Let me see if I can get my GFX peers to take a look at this as most likely it's a GFX driver issue. I'll get back to you as soon as I can.
Thank you cvare!
I've read through several other threads here and in other communities about similar problems with other setups. But I guess there are not enough NUC7 users out there yet, so I really need your help to fix this issue with the Samsung TV.
Please let me know if you need more information, I can send you all the reports as I've been spending a lot of time trying to fix this.
I would like to know a couple things if you can.
First can you download this: Download Intel® System Support Utility and post the results. Just so we know what's on your system as a place to start.
So I was growing tired of this and tried two things:
1st, I bought an expensive and brand new fancy Hama High-Speed-HDMI Ultra HD-4k cable. It didn't work.
Then following MartyG advice I also purchased a USB-C to HDMI adapter from ICY BOX, connected to the same old HDMI cable I was trying directly on the HDMI port, this partially helped the problem. Now I still can't see the intel logo or get to the visual BIOS, however once Windows 10 is loaded it works fine. I can turn off or change source and when I get back everything is fine. Sound works well but I don't seem to be able to get any CEC.
I would like to solve the remaining issues, so I'm attaching the requested information.

Leo, glad that you've made progress with your problem!
Might this help article by Samsung about HDMI-CEC on 2016 Samsung UHD TVs be of any use to you?
