I have 5 HPZR2440w monitors. 4 of them have LIMM03 firmware and 1 of them has LIMM04 firmware. The monitor with the LIMM04 firmware has no issues being used by several different devices that output a DVI signal (FPGA boards, laptops, etc.). in any display mode. But, ALL 4 of the other monitors with the LIMM03 firmware do NOT work with these devices in all display modes. Typically, anything that is 59.9Hz works fine and any other vertical frequency (60.00Hz even) does not work.
So, how can I upgrade the firmware on these monitors?
