    Flux does not apply to monitor that runs through USB to HDMI converter. Any way around this?

      The converter in question is a Cable Matters® SuperSpeed USB 3.0/2.0 to HDMI/DVI Adapter.

        I have a hunch that it's not the adapter, but perhaps the fact that it's due to essentially having the monitor connected via USB instead of directly to a display port such as HDMI, VGA, DVI, or even DisplayPort. I am guessing that maybe the f.lux team hadn't thought of this yet.

        So I'm curious: do you have any other connectivity options? I mean, does it have to be on a USB port with an adapter? Can it be like VGA to VGA, or DVI to DVI, or DisplayPort to DisplayPort without needing to use some USB adapter?

          I don't have any other options. My laptop only has one HDMI port and does not have any other display ports.

            Oh, so you're using the HDMI port on your laptop, and the USB port on your monitor?

              @TwoCables I'm using two external monitors. Both use HDMI input, but one of them uses a USB to HDMI converter. Flux does not apply to the monitor that uses the converter.

                Then I would say the answer is that, f.lux needs to be programmed to recognize displays on USB ports. Either that, or it's something to do with the way Windows is (it might be a limitation that can't be overcome). So, we'll have to wait for the f.lux team. I'll mention them now to get their attention just to see what they think:

                  DisplayLink USB adapters (not the same as DisplayPort) do not support any color correction controls like a normal video card does.

                  The only option remaining is to program the monitor directly, which we have found is flaky and badly supported, so while we can do it for some monitors, we do not ship it. To explain a bit more: some displays flash a lot when you change settings this way, and more importantly: different displays use a wide variety of color spaces, so we can't actually do a good job of changing colors this way - some wind up oversaturated and dark, and others are very washed out.

                  If we had 1000 people with different monitors and hardware calibration devices to help build a database for this, we could ship this, but it's not yet easy.

                    "while we do it for some monitors"

                    @herf can you share the list that you do support?
                    (I'd like it for my old BenQ 241W Z, else possibly I'd switch things around to plugin the USB video card to my Dell U2913WM)

                      I don't understand the montior that uses USB to HDMI converter. Are you forced to use this converter, or do you have the option to connect it directly to HDMI -- you may be able to get an HDMI hub click for amazon, HDMI hub link to have both connected with an HDMI cable.

                        With that hdmi hub you can switch BETWEEN outputs, not use all at the same time. And dual monitor with only one working at a time isn't really dual monitor :P

                          @krugm0f0 Damn! Thought we had something.

                          This will do it though: HDMI splitter

                          Actually that probably won't work either as it's just duplicating the signals.

                            I am having the same issue working on a Lenovo ThinkPad L440 with three external monitors (iiyama ProLite XB2380HS).
                            They are connected one via VGA, one via DisplayPort and one via USB to HDMI DisplayLink Card.
                            Laptop screen, VGA and DisplayPort work just fine, just the USB card won't change colors.

                            @herf Is there any way to get a beta version (or even alpha testing) for programming the monitor directly? I would greatly appreciate any feedback there, since this really would be great when working late or in dark environments!

                              SOLUTION! I got this sorted! I am using MacBook Pro (13-inch, 2017, Four Thunderbolt 3 Ports). I was using a docking station that is connected via USB and then HDMI cable from the docking station to my external monitor. When I started using USB-C to HDMI adapter and then HDMI cable from this adapter to my monitor, it worked. Enjoy!
