BenQ HT4550i: what it gives up
- 60 Hz at 4K — the 240 Hz figure applies only to 1080p
- HDMI 2.0 rather than 2.1, so there is no 4K/120 path at all
- A single 5 W mono speaker, which is a token gesture at this price
- 14.6 lb and physically deep for a shelf
- It lands in the same price band as the brightest 3LCD projectors, which beat it on brightness and black level for film
BenQ X3100i: what it gives up
- HDMI 2.0 caps 4K at 60 Hz; the headline 240 Hz is 1080p only
- ±10% vertical shift is much less than the HT4550i it shares a chassis with
- 15 lb makes it awkward to move between a shelf and a mount
- No Dolby Vision or HDR10+, only static HDR10
- Contrast is the weak point: it is a bright projector that is not optimised for black level, and 3LCD rivals at the price look better on dark material
