I have the new HW-Q900A and I have connected an Apple TV 4K to it. When it is connected to HDMI 1, it cannot do 4K. It will either just cut out the sound while displaying the video or even have the video cut blink in and out. However, with HDMI 2 using the same cable, I can play 4K video with Dolby Atmos perfectly fine. Has anyone else had issues like this? Do I just have a bad unit that has a bum HDMI 1?

If you're using the same cable and it works using HDMI 2 but not HDMI 1 then the port is the likely cause. Have you tried anything else in HDMI 1 to see if it works like a UHD player?
