Breakthrough for people who want to avoid the MSTAR ISP upgrader!
It is now possible to upgrade BENQ Z-Series monitor to Version 2 firmware with absolutely no external hardware — just a direct VGA connection between computer and monitor to install the Version 2 firmware on XL2411Z, XL2420Z, and XL2720Z to make them compatible with Blur Busters Strobe Utility!
Note: The instructions are still very technical. It currently requires a Linux system and a special driver, in order to install BENQ firmwares. The instructions may become simplified as enterprising users find ways to automate this upgrade process.
