I checked Dell’s drivers & downloads page for the U2414H, but there’s listed—only drivers and manuals.
No. Dell does not offer downloadable or user-installable firmware files for the U2414H. Unlike newer monitors, this model does not have a user-updatable firmware mechanism via USB or DisplayPort.
Hey everyone, I’ve got three Dell U2414H monitors in a multi-monitor setup. I’m trying to solve a DisplayPort daisy-chaining issue (MST) where the 2nd monitor goes black randomly.
