So I bought the latest Apple TV 4K, because from what I was reading it seemed** like this would give the best quality picture for my Plex streamed remux files (or at least very close to the best, I preferred Apple over Shield Pro). I did some research and determined** that even if I solved the bandwidth issue with ethernet, the Fire TV Stick was still limiting the picture quality to some degree. I noticed it would buffer at some points even on WiFi 6 (I have a AX5400 modem). I acquired some remux files, bought the Plex pass, and played them on my Fire TV Stick 4K Max. This was good, but it seemed** like there was a lot of quality left on the table with this method. My first attempt was buying some Blu-rays and playing them on my PS5. I decided at some point that I wanted to push my TV to the absolute limit. It did everything I needed, although in hindsight it was a bit slow to start up and navigate, but no big issues. My first 4K device was the Fire TV Stick 4K, and I bought the Max version when that came out too. Since then I feel like I've gone very far down the rabbit hole, but I still feel like there are further depths to reach. Last year I bought an LG C1, and dove headfirst into the HiFi world. Forgive my life story I'm about to write, scroll to the TL DR if you're not interested.
