Our take on the BenQ TH671ST data projector Short throw projector

The BenQ TH671ST is a 1080p DLP home entertainment projector built around a short-throw lens. Its 0.69–0.83:1 throw ratio fills a large screen from close to the wall, and 3,000 ANSI lumens keeps the picture usable with some room light. It targets gamers and movie watchers who want a big image in a small room. Against long-throw 1080p projectors it trades placement flexibility for a brighter, closer setup, but it has no HDR, no smart apps and a lamp that dims over time.
