Make sure that your BENQ Z-Series has the V2 firmware.

That makes sure it is compatible with third party utilities, such as the Blur Busters Strobe Utility.
Wow, thanks!
Does that mean that some older XL2420Z have worse software and they have implemented a new one on the recent ones?
How can I know if it has the new or the old firmware? Does it say on the box?
