These Fire TV tweaks made my streaming setup so much better

I grabbed two TCL 75-Inch Class S5 UHD 4K LED Smart TVs with Fire TV last year, expecting a simple setup—just plug them in and start streaming the next great sci-fi movie on your watch list. Man, was I naïve about that. Spending time on the menus and experimenting with different options showed me that these things can do way more than what you get right out of the box.
