Better for TK710STi
- Recreational Player
True 4K with laser life and HDR — the courses look genuinely impressive and the projector lasts the life of the room.
- Performance Seeker
16.7ms input lag at 4K is well under the 30ms tolerance threshold; 95% Rec. 709 color and laser stability support serious data review.
- Family Setup
4.2 ms gaming lag at 1080p/240Hz makes this a legitimately great gaming projector in addition to a sim and movie projector — best multi-use mid pick.
