The projection distance of R 1 is 10-20cm, and R 1nano is a little further than this. The brightness of peak meter R 1 is 1600ANSI lumens, which is higher than that of R 1Nano, and the projected picture is brighter. Peak meter R 1 uses 0.33DMD display chip, and R 1Nano uses 0.23DMD, so the picture clarity presented is not as good as R 1. Mi Feng R 1 is equipped with MTK9669 processor, and R 1Nano is equipped with AmlogicT972 processor. In terms of chip performance, Mi Feng R 1 is better. Peak meter R 1 adopts circular design, and peak meter R 1Nano adopts square design.
