Projectors / BenQ
BenQ W2720i
Superb 4LED colour and 240Hz gaming — held back by near-zero lens shift.
Overall score 7.4/10
Pros
- + 4LED gives excellent colour volume — 95 to 100% DCI-P3 without a laser's speckle
- + 240Hz at 1080p with 6.5ms lag is genuinely competitive for gaming
- + Real home-cinema optics and picture processing rather than a lifestyle design
Cons
- − ±5% lens shift is close to useless — placement is rigid and you will rely on keystone
- − Brightness drops from 2,704 to 1,595 lumens once you switch to an accurate picture mode
- − Reviewers found the bundled QS02 dongle stayed locked in HDR10 mode and did not switch dynamic range correctly
- − No Dolby Vision
- − BenQ runs several parallel Amazon listings for this model
BenQ W2720i review: what the specs say
Superb 4LED colour and 240Hz gaming — held back by near-zero lens shift. At $1,966, BenQ's 2025 model sits in the middle of the range — the projectors we compare run from $499 to $7,999. It scores 7.4/10 overall, calculated from published specifications across 8 categories rather than from a subjective impression.
Its strongest showing is Color at 9.0/10 — colour gamut coverage and accuracy out of the box. The weakest is Setup & Placement at 6.0/10, which is the trade-off to weigh before buying: if that is the specification you care about most, one of the alternatives below will serve you better.
Worth knowing before you buy: ±5% lens shift is close to useless — placement is rigid and you will rely on keystone; and brightness drops from 2,704 to 1,595 lumens once you switch to an accurate picture mode. Every specification on this page comes from BenQ's own documentation or a verified retail listing — where a figure is not published, the table says so rather than estimating it.
