I recommend a projector. When we moved into our current place, I considered a TV and went with the projector instead. Because:
- A TV has a backlight. It doesn't feel as 'natural' to the eye when watching because you are staring directly at an LED.
- A TV is smaller than a projector.
- A TV, when it is off, imposes itself on the room. It's a large plastic/glass object which is obviously electronic. It invades the space.
- Most TV's are full of surveillanceware.
- A TV can be watched even during the day, when it's bright outside. The projector, by contrast, is much less pleasant during the day; I consider this a feature - I should be doing something else when the sun is out. (The only time this kinda sucks is sports. We make do with closing the curtains).
- Movies were made for the silver screen, imho. This might be a hipster opinion but in my view, the medium really does make a difference in this regard; the moviegoing experience is better.
To specifically answer your question - most projectors are just a dumb HDMI cable. Computer, media center PC, apple TV, etc. None (unless I'm not aware of newer models) have an app store, tracking, or other garbage.
I've wanted a projector for so long, and had the chance to borrow a friend's high quality one to test it out. It absolutely elevated the movie experience and - depending on the viewer's preferences - could be worth it for that alone.
However, this:
> The projector, by contrast, is much less pleasant during the day
Was a significant enough drawback to me that it ruled it out as a daily driver. Although I do like the way you framed it.
