MannT: Thank you very much for joining the Intel® NUC communities.
In order to try to fix the problem, we can try to install the latest graphics driver for the NUC, which is 4664:
Also we can try a BIOS update to the latest version 0038, on the link below you will find the instructions of how to do the update using the F7 method and the file needed:
Please let me know the results of trying the steps above.
Any further questions, please let me know.
Thanks for your answer Alberto!
But, as I mentioned, I updated everything, BIOS 0038 and the latest graphics driver 4664.
Tihs DP converted to HDMI 2.0 seems to make a lot of trouble!
Is it a hardware failure and should I sent it back to me retailer to get a new one?
For now, it is okay with 50Hz, butit should not be like that. What is goint to happen if I connect a 4k TV?
Maybe it is not compatible with my TVs HDMI 1.4? It is s strange problem, I never had such a flicker before...
Where do you live? Is your AC power running at 60Hz or 50Hz? If it's 50Hz, then this should be your target (shouldn't it?)
Germany with 50Hz. Hm, the AC unit should work with 50 and 60Hz right?
I never had that problem with every PC or Laptop I ever owned.
But this seems to be the right direction, I look into it later...
It is a 50-60Hz Power Unit and should work fine in Europe.
I will test it with another one...
Thank you very much to N. Scott Pearson for the suggestion provided above.
MannT: Thank you very much for providing that information.
Perfect, if you have the option, please test it with a different AC power and let us know the results.
Also, there is another driver version that we can try for the Intel® HD Graphics 500, version 4678:
By any chance, do you know what is the model of the DP converted to HDMI 2.0 cable that you are using? The thing is that when you use a converter there might be some configuration issues depending on the quality of it.
On the link below you will find the list of tested peripherals for the NUC where you will find some TVs and adapters listed:
Any questions, please let me know.
I gave the NUC back and got a G4560.
I did not really solve the problem, but i guess it was hardware problem (or a driver...). I close this thread...
Tahnks for your help guys!!
I think the cause is due: graphics driver or AC power or Poor quality HDMI cable. You can try to self-test these causes !
The first thing I did was updating the graphics driver, reinstalling, updating, testing another one, complete OS reinstall...
Second, tested different HDMI cables...
Third, changed the complete enviroment and the AC power...
I guess it was some kind of hardware failure...!?
MannT: You are welcome. Thank you very much for letting us know those details. We are sorry to hear the problem was not fixed. And yes, based on the information posted above everything indicates it was a hardware failure.
Regarding your new Intel® G4560, if you use HDMI 1.4 the max resolution will be 4096 x 2160 at 30Hz. If you use HDMI 2.0 the max resolution is 4096 x 2160 at 60Hz, so the processor supports the configuration you are trying to use, page 42:
For the board to have an HDMI port and cable version 2.0 is required in order to be able to use 60Hz. Please let us know if the board complies with those requirements.
Any questions, please let me know.
Thank you for your help. Everything is working fine now with the new CPU...
MannT: You are welcome. Thank you very much for providing those results. Perfect, excellent, it is great to hear that everything is working fine now with the new processor.
