Common questions

ANSWERED FROM THE DATA

How bright is the ViewSonic LS901-4K?

5,500 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.
