That's still not good. I recently switched from a Sceptre dumb TV to a top of the line LG OLED model, and it is sooooo slow. Everything takes forever because it's got to wait for the network connection which doesn't exist, play all its stupid animations, run the "AI" bullshit, and attempt an internet connection again.
Then you did it wrong. The tv should be turned on and set to display one port, say hdmi1 then never touched again until its time to shut it off. Volume should be handled through hdmi-cec from the tvs perspective it should get an on or off signal and maybe some volume signals and it should display hdmi and that is the entorety of its existence.
I guess that's fine if you only have one device connected to your TV, and it supports CEC.
That is not my use case though.
