There are no firmware updates for my Onkyo TX-NR 906.
I am using a simple HDMI to HDMI cable to connect the NUC with the AVR, if that's what you mean.
I also tried 3 different cables but no luck.
The picture that NUC outputs to Onkyo is incompatible at 50Hz (such as the boot screen). Every other refresh rate is ok.
Is this something that can be fixed with a bios update? I would like to know please...
