I've used projectors for the past 15-odd years. Modern ones are very, very good in that they're portable, can run on batteries, don't need to be plugged directly into your laptop etc. The trade-off is that we don't really watch anything until the evening. The only ads we see are the ones from streaming services.
Yeah, my setup the last couple years has been a 4k projector + blackout curtains + casting movies via Airplay from my laptop. The screen ends up being over 90" horizontally (haven't measured diagonally). Zero ads, and the curtains make it usable even with sun hitting the window.
