I setup my new Nuc was running two days perfectly. But now, I don't have any output on the HDMI. No Nuc logo at boot time, no OS booting.
Only a black screen. The TV says, there is nothing at the port.
I tried with different HDI ports, same results. Nothing.
The nuc itself, works fine. I'm able to login from remote.
Then Nuc is a new NUC8i5BEK with the BIOS 071.
The TV is a Samsung 40" Flat UHD TV
Model UE 40KU6079U
For setting up the Nuc it worked fine in UHD mode. But all of the sudden: no output any more.
I switched now to a (also Samsung) PC Monitor. With a DVI Interface. I'm using a HDMI to DVI cable.
Here everthing works fine. So I guess nothing wrong with the hardware.
If I can't connect to the TV, one of my usecases for the NUC is gone.....
A few more questions to pinpoint the problem:
I'd agree with Leon in suspecting the HDMI cable, which might not be able to handle 4K@60Hz signal.
