I have the following setup:
LG 4K TV, HDMI 2.0 and HDCP 2.2 capable
Onkyo TX-NR626 receiver, HDMI 1.4 capable
Nvidia Shield TV, HDMI 2.0 capable
The issue is that I have some 60Hz video that I want to play from the Shield, but the receiver can only handle 30Hz. So I want to run the shield directly to the TV and use some kind of audio return back to the receiver. Anybody faced this issue and played around with it? Using a splitter? Optical back to the Onkyo maybe?
