hi all.

I finally upgraded my ATV 4 to ATV 4K after using it since 2015. I have some question if anyone here can help to answer:

1. My old ATV 4 is dead. No power. I tried to bring to Mac City service center but the guy said it is not repairable (if under warranty it is 1-to-1 replacement, no repair service). Is there any other place I can check?

2. I am using a quite old Samsung NU7300 4K tv. What is the best way to set ATV 4K? From what I read, I use 4K SDR 60Hz, enable content match. For chroma I set to 4:4:4 even though I have no idea what's the different.

3. Related to no. 2 above, how should I set my TV? I currently use the Standard settings. Previously I use Dynamic when watching movie (running from Netflix samsung app. because my old ATV4 does not have 4K).

Thanks in advance!
