    The wallpaper above has quite a few artifact on my second monitor, mostly around darker areas.

    My second monitor displays artifacts no matter which port i use to connect it to my PC (tried dport and hdmi) or even which adapter (tried both integrated Intel HD graphics and Nvidia 970).

    Problem with blue artifacts on secondary monitor connected with DVI-D
    Main monitor is okay (connected with VGA->HDMI converter)



  • Have posted v4.115 with a fix, and it is set to update for people on the May 2020 build.



  • This post is deleted!


  • Hello! I received a notification about version 4.117 being installed and about "Solar Time". The release note says "We added “Solar time” to the preferences", but I can't that in the preferences.
    Is it ON by default?

    EDIT: Wait... Is it only the "Solar time: XX:XX" text?



  • Yes, we didn't really finish this still as more of a feature - so it is still only informative. More to do here.

    If you're on DST right now, you'll find the solar time is quite a ways from your wall clock, but this may be a nice thing to know.



  • Hello,

    I can confirm v4.117 is working good. I no longer see blue/green artifacts.

    Thanks!



  • I also can say that v. 117 and now 118 seems to work fine. Thanks

    Issue: Broken color gamut, warmthness is nowhere near expected values, amber almost looks greyscale (colors appear normalized instead of filtered with a color correction table or w/e)

    What I think happened: F.lux started, expected color translations/filters were applied correctly, f.lux auto-updated, the notification rendered, and the color low end of the color gamuet broke.

    Always use internal color table is a viable workaround



  • Thanks for the note that "internal color table" fixes it.

    We try to auto-detect, but the detection is not working very well as of this update.



  • Hi, I just upgraded to 2004 and seems like the brightness span of f.lux is reduced, I cannot go very dark as I did before. I have an Intel HP laptop with intel graphics and nvidia quadro. f.lux is 4.118.
    Any hint is appreciated.
    Thank you.



  • Hi did f.lux prompt you to expand the color range?



  • @herf yes, but I guess I dismissed the alert, but eventually I expanded manually via the context menu from the f.lux icon (change current color - expand color range). But didn't change anything.



  • @paul741 It does require a reboot - however, if this doesn't help, can you post f.lux options > driver info?

    Alternately, in f.lux options > "Always use Windows internal color table"



  • @herf I don't know what happened but know it works (without the windows color table option). Thank you.



  • If you want to install the update now, select Start > Settings > Update & Security > Windows Update , and then select Check for updates.



  • I am still getting the yellow screen when taking screenshots. I am on latest Flux version, and latest Windows 10. Why is this still happening?



  • @Mysticode Can you post f.lux options > driver info?





  • Any update on this @herf ?



  • @Mysticode this is saying two of the monitors don't support gamma ramps - how are they connected?



  • DP, via a USB-C hub to my laptop



  • @Mysticode can you post the model number of the hub so we can see which chipset it uses?

    We are supporting DisplayLink (by name) for these USB-C hubs, but there are some other vendors we would like to try to improve, but right now I don't think they have support for color controls. If it's DisplayLink we can probably get it to work.



  • @herf In this situation, it is a USB-C docking station by Dell. I can't find a model number, but it's for the Latitude line of laptops.



  • @herf I also have this problem - Dell D6000 dock, notably with DP to HDMI adapters
