The M2B102 firmware is now on the U2718Q driver page.
* Unzip the file into its own folder on your Windows operating system computer
* Open and read through the (DELL_U2718Q_ISP_TOOL_SOP.PDF) instructions before proceeding
I have not seen the update in action. Was it hard to perform? Could the instruction PDF been better? If yes, how?
For me it was impossible to update the firmware, i'm running a mac. Will there be a mac version in the future?
<No. The U2718Q was only validated for Windows 7/8/8.1/10. DELL-Chris M>
The update process was relatively painless, and I can confirm that it fixes the DP color issues.
The only snag I ran into was during initialization of the firmware update process. I had to power cycle my monitor and then restart the software for it to detect the monitor.
I was able to update the firmware without problems and everything happened perfectly. The colors are perfect now. After reading the manual, I had no doubt about the process, and everything happened as expected.
I knew Dell would not ignore us.
Thank you very much.
Unfortunately, the U2718Q was never validated by Dell for the Apple proprietary hardware, operating system, and drivers. When you go to the U2718Q driver page, you can see under "Operating system:", that only Windows 10/8.1/8/7 are validated. The U2718Q User's Guide also never mentions Apple or MAC. You will need to find a Windows system to run the firmware update.
