Okay, so I'm having a helluva time with the UN75NU8000... I am running all components (DirecTV, PS4Pro, Oppo, AppleTV) to my Pioneer SC-97 and from there to the Samsung and a projector. The projector has no issue when I power on or switch sources. But the Samsung take forever to get a signal. I have to bounce between the Oppo, DirecTV or AppleTV, over and over, and eventually I can get past the "no signal" prompts. It's maddening... I've tried ARC on, ARC off, replaced my HDMI cables with hi-speed fiber, reset the TV, unplugged and plugged in. I just don't know what to do to get a handshake and I have been combing through this forum to no avail.
Anybody else with these pieces in their system have similar issues?
