Common questions

ANSWERED FROM THE DATA

Does the BenQ TH685P need a special screen?

No UST-specific constraint — the BenQ TH685P is a conventional-throw design per its stated throw type, so standard screen materials work. In a room with ambient light, an ALR screen preserves contrast; the builder checks the projector-screen pairing either way.

How bright is the BenQ TH685P?

3,500 lumens, as claimed by the manufacturer. Brightness figures are measured in flattering picture modes, so expect less in an accurate cinema mode — they're still the right way to rank projectors against each other, just not the number you'll see on the wall.

Computed from this product’s normalized, source-tracked fields — an unstated spec reads as “can’t check”, never as a yes or a no.
