Final Verdict

Both are 4K UHD DLP projectors built for console and PC gaming, with fast 1080p/240Hz modes and around 16ms at 4K. The Optoma UHD38x, successor to the UHD35 and UHD35X, is the brighter of the two and the better pick for living rooms with ambient light. The BenQ TK700 has the longer track record and much larger review base, and its picture tuning suits mixed movie and gaming use in a dimmer room. Bright room: UHD38x. Dim room and a proven model: TK700.
