      I installed f.lux V3.12 and it worked only on a single monitor. When I installed it I was running on only a single screen via remote desktop (RDP). When I came to work and used the PC physically in the same room only one screen was affected by f.lux. I re-installed f.lux over the existing version and by doing this I found that both screens were then affected as expected.

      I have not tried rebooting the machine yet as it's possible this might affect behaviour. If it reverts to working on only a single monitor I will repost to this forum.

        I had the same problem but the problem seems to be solved at this moment.
        As @MrSwadge mentioned above, I also re-installed f.lux over an existing software and then the filter is now applied on both monitors.

          @ReCrunch this came out yesterday which might be helpful for those using Display Link USB adapters http://www.displaylink.org/forum/showthread.php?p=82958#post82958

            Just FYI for anyone coming here with Windows 7 and Intel HD Graphics 4600, I updated my display drivers and that did the trick immediately.

              Hello,
              I knwo it's been a long time since the question came out.
              But I had the same problem and I find a solution.
              After you instal F.lux, you see that it works only on one screen.
              Then, you change your theme in the seeting of the apparence of the screen. You'll see that F.lux automatically apply on both screen !
              (sorry for the mistakes, I'm from Belgium :) )

                  If anyone finds this old thread, LastStar007's post fixed it for me. Quit f.lux and Run as Administrator did the trick.

                      this sometimes fixes the problem for me
                      click the lower timeline on the flux interface to get the "24 hour preview"
                      turn off your second monitor and turn it on again to see if flux has gone to it
                      if that does not work, close down flux and restart it with the second monitor on
                      if that fails, do it again with the second monitor off and then turn it on

                          [POTENTIAL FIX/SOLUTION]
                          Old Thread but in case you are still looking, this simple trick solved it for me!
                          From the display settings you can toggle which screen to make your main display.
                          Alternating between the available screens seems to have fixed the issue for me.
                          e.g. you have 2 screens (A and B), set monitor A as main display -> set monitor B as main display = profit!
