Hello, I'm pretty much a Roku beginner. I have an LG TV which supports 4K HDR. I have an anthem MRX 720 AV Receiver that also supports 4K HDR. The HDMI cable coming out of my Roku ultra is plugged into a HDMI input port on my Anthem. The HDMI output on my Anthem is connected to my LG TV. I'm quite certain that my Roku Ultra supports 4K HDR. So how come my Anthem A/V receiver is showing 1080p coming out of the Roku. is their a configuration or setup issue? Thanks --TIm
