Our Verdict
ViewSonic PX701-4K
Optoma UHD35
The Optoma UHD35 is a bit better than the ViewSonic PX701-4K. They're very similar projectors, with both capable of 1080p @ 240Hz for gaming. However, the ViewSonic has significantly worse color accuracy than the Optoma, and the Optoma also has a slightly wider color gamut, giving it the edge over the ViewSonic.
