Asked by: huanghe

I do have NUC with Kodi connected to the AVR171S which in turn is connected to a 4K TV. However, Kodi set to 4K via the AVR171S gives me only 30Hz on display. If I connect the NUC directly to my TV I get 4K at 60Hz. Do I have to use a specific HDMI port?

Wow! It seems if really worth to ask here from harman/kardon. Congratulations on good brand building. It does not seem to be worth replacing my good old Yamaha amplifier.

Is the 171S compatible with Movistar TV decodifiers? I can no longer get their signal through in my old A/V receiver and I need to be sure before changing.
