Problems persisting after 1903 update

  • After reading through some of the posts here, it seems that the issues relating to the 1903 Windows update have been resolved, but I am still having some problems with f.lux that I'm hoping I can get some help with.

    I have a laptop set up with 2 additional monitors plugged into it. Ever since the 1903 update, f.lux only seems to affect the monitor that is built into the laptop itself, and does not change the colours displayed on the external monitors. I have tried using f.lux with fast startup both on and off, and it seems to make no difference for me. I also opted into the beta program, and this also had no effect for me.

    Is there anything else I should be trying to diagnose this problem? I'm very willing to post logs or anything like that, but I'll just need a bit of direction in where the find them.

  • It helps most if you post f.lux options > driver info.
    There seems to be a problem with AMD Vega adapters, but we are not sure yet what it is.

  • Sure, here's a screenshot from that screen -


    So f.lux is working on the "Generic PnP monitor" (which is the laptop's built in monitor) and not working on the two HP W2371d monitors.

  • The DisplayLink devices sometimes require a small registry change -- see

  • Fantastic, that did the trick. Thank you!
