The setting of the appropriate "EQ" levels (What's that .. ??) according to instructions did not work (determining a working area, the center of which is then set), and I have already several times the entire area by Gege turns completely: Whenever exposing the image, continue to turn until it went away. For the moment. Because it held only for a while and remained permanently stable on any setting.
On my BenQ W1070, however, everything works without any major hiccups, incl. 3D. Only when you switch it sometimes takes a little longer and turning off the 3D mode it comes now and then to a color cast in the image; but disappears when you switch again. Had I not anyway just replaced the projector, I would have looked in the tube.
CONCLUSIONS: not bad per se, but a little thin idea, even for a budget item.
