Optoma GT4000UHD.
Ultra-short-throw 4K UHD with 4,000 lumens — a rare combination.
The Verdict.
Gavler Meta-Score
“The ultra-short-throw projector for rooms that aren't perfectly dark. Most UST projectors demand blackout conditions to look good — the GT4000UHD's 4,000 lumens let you use it in a living room with the blinds partially open. Gaming performance is a bonus that most UST competitors can't match.”
