Final Verdict
Both are entry 4K DLP projectors with fast gaming modes at nearly the same price. The Optoma UHD38x is the brighter unit — the better choice for rooms with ambient light. The ViewSonic PX701-4K counters with a much larger, stronger review record and 240Hz support at 1080p. In a dark or dim room, take the ViewSonic; in a living room with windows, the Optoma.
