If you are using Windows Anniversary edition, DisplayLink have made f.lux work with USB-connected monitors:
Due to a bug in Windows, you will have to undo this change if you want to uninstall f.lux. (Your main display will continue working in any case).
@herf This is wonderful news! Very encouraging for the future of this display connection.
Flux v4.21 seems to be working perfectly with DisplayLink's 8.1 &8.2 beta drivers. This using DLink on my AOC e1659FWUX
This is also pre-Creator's update.
I have some Asus USB monitor that uses DisplayLink, Will have to test it out with flux If I can find where I've put my USB3 cables.
