Epson Home Cinema 3800: what it gives up
- 60 Hz ceiling — no 4K/120 and no 1080p/120, so it is the wrong projector for a current console
- A 250 W lamp rated 3,500 hours in normal mode is the shortest light-source life in this catalog
- Released in 2019: HDMI 2.0, no eARC, no streaming, and no HDR10+ or dynamic tone mapping
- 15.2 lb and physically large for a shelf; this is a ceiling-mount projector
ViewSonic LX700-4K: what it gives up
- Lens shift is downward only (-15%), so it wants to sit above the screen line
- HDMI 2.0 caps 4K at 60 Hz
- No smart platform at all
- A single 15 W mono speaker
- Its throw ratio sits between the usual short-throw and standard-throw bands, so an existing mount frequently has to move
