Final Verdict

The GT1080HDR is the speed pick: 8.4ms Enhanced Gaming mode, higher brightness, and a tighter 0.5:1 throw that makes 100 inches from about 3.5 feet. The TH671ST answers with better out-of-box color and BenQ’s reliability record. For pure gaming in a small room, Optoma; for a short-throw that also does movie night duty, BenQ.
