I just bought cheap Deathadder Chroma, and it seems to be fake (hardware looks just as regular one, but synapse does not recognize it).

So my problem now is how to change dpi?

I cannot return it, so I wanna ask you guys is there any way to change dpi, if not I guess I can put my old deathadder 3g sensor in it which is already set to 450dpi.

Advice is welcome.
