Searching the best settings for Apple TV 4K and Q9F

Hello everyone, I bought my new apple tv 4k and right now I’m a little lost with so much information. I’m looking for the best settings for my apple tv and my samsung tv q9f (I have a sound bar lg sk5r, connected by hdmi arc). I would like the recommended configuration to take full advantage of this product’s potential. Currently the use that I will give is to watch movies in 4K remux or full 4K. I hope someone can help me and I appreciate your time. Cheers

Make all connections for your networking Ethernet. That’s including the NAS, ATV4K, and internet.

The rest should work fine.
