I have external speakers, I never use the speakers in my TV. I have a streaming device, I never use the streaming features built into my TV. My streaming devices have their own remote controllers which interact with the TV using HDMI-CEC, I don't use my TV's remote controller.
All the "features" built into my TV are obstacles that I'm happy to pay to have removed. Due to the speakers being built in, the TV likes to randomly switch to those instead of my external ones. The streaming apps lead to the TV having an entire operating system of its own which causes it to take longer to power on, longer for me to get to the things I want and more complex to interact with and configure.
I essentially just want a really big PC monitor. Just give me something that takes a digital signal in and beams corresponding coloured lights into my eyeballs.
