Hi Gianpiero: Thank you very much for contacting the Intel® NUC communities. We will do our best to provide the information you are looking for.
To deliver the most accurate response we just wanted to check a few details about your system:
What is the model of the monitor?
What is the model of the home theater?
What is the model of the switch/receiver?
We can try a BIOS update to the latest version, 0367 using the F7 method:
Also please try to install graphics driver 4624 or 4835:
Any further questions, please let me know.
Hi Gianpiero: Thank you very much for providing that information, we really appreciate that.
We will start a research on this matter, as soon as I get any updates I will post all the details on this thread.
Any questions, please let me know.
I checked the KRFV5570D manual at https://manual.kenwood.com/files/B60-5337-00.pdf and I dont see any HDMI input/output on the receiver itself, am I correct?
Do the images attached to the post belong to the switch/receiver MOSOU CONVERTER - HDMI to HDMI + AUDIO? If that is the case, it is very possible that having this switch in between may be causing the issue.
I would recommend that you check the following guide regarding Home Theater/ AVR set up, https://www.intel.com/content/www/us/en/support/articles/000008497/mini-pcs.html also check here: https://www.intel.com/content/www/us/en/support/articles/000008497/mini-pcs.html
