For this model, there is no customer firmware upgrade functionality.  Currently all Dell monitors that have the Nvidia G-Sync module can only be firmware upgraded via the Dell Service Center. But, you can only get one of those via an exchange.
It has become evident that the firmware for the AW3423DW has been revised at least once or twice (from M0B101 to M0B102 and possibly M0B103) since release. This is an expensive, enthusiast grade monitor and we'd like to have the option for the latest firmware on them. Instead, early adopters are stuck with what they receive – bugs and all. You appear to have the capacity to provide this based on existing support guides. Why isn't this available for the AW3423DW? Please advise. Thanks!
AW3423DW, please let us update firmware
