I own 3 AOC monitors that use isplay link drivers. None of the monitors work with chrome books consistently. they all work with windows fine. These chromebooks are all above the min OS version and are Acer and 2 identical Samsung.s Monitors work on one samsung but not the other. Monitors worked on ACER until about a month ago and now no longer work. in all instances i get the floating USB connection image. THere is power to the monitor but the chromebookd does not understand to send a signal to the monitor. Can you please unbreak the "inboxed" driver so the displays work? Or make a driver available to download and manually update? Thank you

Firmware update of the DisplayLink chip is non-optional and is happening on all OSes, transparently. It is not possible for the user to change the DisplayLink firmware selectively, even on Windows. You might be referring to other firmware for other technology your product can integrate. We can pass this onto the device manufacturer.

I can also pass your feedback about Multi Monitor Software to them. This is a third party whose software works with or without DisplayLink technology.

Which item(s) from DisplayLinkManager are you missing?

The driver is inboxed indeed, however the Windows DisplayLinkManager and "Multiple Monitor Software" offer much more functionalities.
In addition - it possible to preform firmware update from Windows only - very problematic since I don't have a Windows computer.
