Flux not working on Dual monitor setup with USB 3.0 to HDMI adapter



  • Hello guys,

    I have set up two monitors this week. On is directly connected to my Laptop via HDMI, the other uses an USB 3.0 to HDMI adapter since I only have one HDMI port on the Laptop.

    The problem is that flux works fine on the primary monitor which is directly connected to the Laptop via HDMI, however it does not work for the monitor which is connected via adapter.

    I have Microsoft 8.1 so I dont have the opportunity to use the built in night mode sadly.

    Do you guys have a solution for this ? Does it have to do with the adapter I am using or is it a software problem ?

    Thanks for your help in advance
