The BenQ service page lets me adjust strobe duty and phase. I tried different DVI port of my GTX670 but there is no difference - what else could have gone wrong?
This type of issue can be quite challenging to track down. Which graphics drivers are you using? Also, I have heard that sometimes a specific DVI cable causes problems, because it uses the DDC/CI wire of the cable, and if that wire is missing, it will become unable to control the monitor. Switching between DVI and DisplayPort can help, too. Also, versions of Windows can influence this. Trying a different computer can help (even a laptop) before switching back to the original computer for playing.
As a last resort, yes, the BENQ Service Menu will allow you to adjust the settings (but at greater difficulty and inconvenience). You will want to enable Single Strobe, then adjust Strobe Duty / Strobe Phase in lieu of Persistence / Crosstalk. You will have to readjust everytime you use a different refresh rate, though. Future Versions of Blur Busters software will likely provide enhanced features, such as separate memories/profiles for each different refresh rates.
