A:Answer Wait, what? If you use your receiver why is it not sending the content to the TV upscaled? The TV handles HDMI 2.2, 4K UHD etc. All connections are made through the one connect box. And the box does accept HDMI 2.2. It also has an audio out via optical connections. All HDMI main connections are done through the one connect, it does have usb and HDMI connections on the side too for quick connections. SD cards too. I run everything through my receiver as well. My Amazon stick is connected to the back of my receiver, it upscaled too if possible. However Amazon, Apple, Hulu streaming is not 4K. I do not know of one service that is 4K streaming yet. Purchased content is, however rented movies,shows etc are nit. Hope this helps buddy.
