5 screens: 4 of them are flickering, one is not doing anything



  • [Hi there,
    I have a 5 screen setup. I have disabled DDC/CI.

    See video here: video

    4 of the screens are flickering when I turn f.lux on. The 5th screen are not doing anything (no difference if f.lux is on or off). The 5th screen is connected with a standard VGA cable to the graphic card that is built in the motherboard.

    OS: Windows 10.

    Motherboard: Asus M4A88TD-V EVO/USB3.

    The 4 monitors that are flickering are connected to these graphic cards:

    AMD radeon HD 5450.
    AMD radeon HD 6800.

    It's connected with either HDMI, DVI or VGA cables.](link url)



  • F.lux usually only changes color on one card. Do you have enough ports hook up 4 to one GPU?

    Also try the following:
    Uninstall f.lux. Connect as many monitors as you can to the bottom GPU. Then describe if f.lux works on all those screens.

    Then uninstall f.lux again and setup as many monitors as possible on the top GPU and then reinstall f.lux!
