Final Verdict

They’re closer than the model numbers suggest. The TH575 is a touch brighter; the TH685P cuts input lag roughly in half (about 8ms vs 16ms at 1080p/120) and accepts 4K input. Competitive players should pay the small premium for the TH685P; everyone else can bank the savings with the TH575 and never notice.
