Installing this beta successfully got f.lux working for me. The problem I am now having is that when I reboot while DisplayLink dock is plugged in, my external displays stay black until I log in, and remove/re-plug the usb connection once or twice. Any thoughts?
Setup: Dell Precision 5510 DisplayLink D3100 2x Dell P2414H (one connected via DisplayPort cable, one connected via HDMI > DVI cable) |

Hello,
Which OS version are you using? If you are using 14393, this could be because f.lux has not yet started and therefore you are hitting the OS bug I flagged in the limitations. The OS is sending 0 gamma tables (instead of default) which kind of means blank (it means all black). But this is a valid value so we can't just discard 0 gamma curves as it could be used by applications to an "artistic" progressive blanking. Microsoft has been EXTREMELY responsive in fixing this as they fixed it within 1 HOUR of me flagging this to them! But the fix won't be applied to 14393. If we discard the 0 gamma tables, then a screen blanking may never be totally black which may become a security issue in screen sharing applications. Do you think it is better? I am really hesitant to implement this as this is going to be very short lived: you are getting the new official OS (Creators Update) with the proper fix in less than a month. I need to balance effort (=> cost) with payback. I'm interested in getting your feedback on this so I take a proper decision! Instead of replugging the device, could you please try to force f.lux night/darkroom mode from the laptop/direct display? If you recover your indirect displays, this is the OS bug. If you don't recover your displays, our engineers need to fix that! (please give which Win10 build you are using for our internal reproduction and analysis). Kind regards, Alban

Hi, is there any chance that a fix might be in the works for Win 7?
I have 2 monitors attached to my laptop through the DisplayLink USB dock, but only my laptop screen is affected by f.lux. |

Hello Ottadini,
It's not really a fix but a new feature. But semantics aside, yes, I have a team on writing the code for this. It's almost complete and they have some automated tests left to do to defend the feature, and also we have to do the full GPU compatibility tests. I hope to be able to release on Win7-Win10TH2 and Win10RS2 (so everything but Anniversary Update which has the gamma bug) for our v8.3 in/around July for devices with Hardware IDs starting with USB\VID_17e9&PID_43. Kind regards, Alban
