May I know if there is a plan for Dell to release U2718Q f/w "M2B103" to public in the near future? It seems that Dell factory has cut-in M2B103 for REV A04 of U2718Q recently.
As of today (11/6/18), M2B102 dated 1/19/18 is the only firmware online. If by public you mean purchased NEW directly from Dell, then yes. It is likely that you would get the latest firmware on it. I doubt any reseller would have M2B103.
