Please keep me posted! I can only get Apple TV 4K 30hz though the receiver. I can’t get anything else to work. Arc doesn’t work for TV apps, can’t get a picture with my 4K Blu-ray player. Only static. Frustrating! Hope you have better luck!@Paradigmshift0 I have an Onkyo TX-NR636 and am scheduled to have the new tv delivered on Saturday. On the last setup, the Apple TV4k, Amazon Firestick 4K, and the 4k Blu-ray player all worked flawlessly through the Onkio. The only connections on the TV were the ethernet and HDMI 1/Arc connection to the Onkio. I'll get it all setup this weekend and test it out.
