As someone who shares your concerns, as well as the privacy concerns, I got a projector a few years back and never looked back.

I'm not one to care too much about picture quality and all that so my $300 projector is the perfect device for me: - Turns on pretty quick just has to warm up - Fully dumb, no internet connection or crappy web UI - Giant screen for me to see from anywhere comfortably seated in the room - I just hook up my computer with HDMI for steaming, nice speaker hooked up with 3.5 mm audio
