The U4919DW macOS firmware M2B108 was released today (10/10/2022) =Dell_U4919DW_FWUpdate_M2B108_macOS.zipInstall it and then retest macOS DDPM 1.0.2.0017. Do not get confused and download the similar named Windows OS M2B108 firmware =Dell_U4919DW_FWUpdate_M2B108_Windows.zip
The DDPM (Dell Display and Peripherals Manager) product/driver page was recently updated to show that the macOS version of DDPM 1.0.2.0017 is now available for my Dell U4919DW monitor. However, after updating the monitor's firmware to the latest version (M2B907 - 8th February) and installing the latest Mac version of DDPM (1.0.2.0017, A00 - 28th September 2022), I still get the error message "Connect USB-C or USB-B cable, turn on DDC/CI or update monitor firmware". I'm connected to the monitor via USB-C from an M1 Mac running the latest version of MacOS (MacOS Monterey 12.6) and have confirmed that DDC/CI is switched on in the monitor's menu. Any suggestions? Thanks.
