Difference between G and B series

Whats the difference between bulk and retail series of BenQ 1640?
I dont find any BSMB for bulk version. Only BSLB.

Hi :slight_smile:
Normally the term Bulk is used for oem drives & naturally retail is what it says.
However on this occassion BenQ appear to issue both oem & retail with BS** f/w(retail). I’ve only ever seen GS** f/w(bulk) on third parties hardware.
Look here for the f/w. Note only one for “bulk” GSHB which is the equivilant of BSHB.

Ok, thanks :slight_smile:
