I just purchased a 976 and a LG OLED B9 55" TV...4K looks fabulous (running through the 976's HDMI 2.0 ports)using a cheapo media player that does have HDMI 2.0 / HDCP 2.2...I also just purchased a HP Omen x 2S laptop...a 'gaming laptop' with an NVidia RTX 2070 video card that supports 4K...when hooking the laptop up to the 976 HDMI 2.0 ports there was no picture at all...nothing...when using the older HDMI ports on the 976 the picture stuttered and blinked about every 5 seconds...so- I hooked the laptop up to the LG TV directly and voila! There was that fabulous 4K picture. I was able to ARC the audio back to the 976 with no problem, but the 976's HDMI 2.0 ports simply do not work with the HP Laptop/NVidia RTX 2070 video card.

Any ideas?
