Nut S1, MI A1 and Benq i950 three models all use 0.65 inch DMD chip, physical resolution has reached 1080P, brightness is also similar, so from the projection of hardware parameters, the three are similar, picture quality is good or bad to see everyone's respective training, previously seen nut S1 and MI A1 picture quality comparison, Nut S1 is basically suspended, the whole picture is biased, Benq i950 has not seen, but Benq is a veteran projection factory, the quality of the image should not be bad, so the basic nut S1 can not be considered, mainly look at the pole meter A1 and BenQ i950 on the line. Personally, I recommend the Ji Mi A1, because the Amlogic S905X processor used by the Benq i950 is much worse than the Mstar6A938 used by the JI Mi A1, which can not keep up with the high requirements of hardware performance in the current Android ecosystem, and the JI Mi A1 also supports the large-screen motion compensation function. When watching blockbusters, there will be no problem of trailing laser TV pictures in the past.
