Okay we do know that NVIDIA has some settings in its own control panel that override color settings - can you check for "reference color" mode or something like that in the NVIDIA Control Panel? It should be turned off for f.lux to work.

@herf I checked out the link you provided. There is no profile for my monitor in the TFT Database. My monitor is the BenQ EX2510. So I was able to get f.lux to work with QuickGamma. So far flux and the QuickGamma settings are working together. Even after a restart. The only (new) problem I have now is with Windows Photo Viewer, but that is unrelated. And also unmaintained software in Windows 10. Time to ditch it, unfortunately. Thank you for your help!

"The topic you are replying to is quite old. Would you like to create a new topic instead, and reference this one in your reply?" No I don't. But yes.. the topic is old, like the problem that wasn't fixed^^ I'm sorry F.Lux, I really like the application you provide to us for free^^ but seeing a four year old problem adressed and looked after by the staff is just a little bit on the funny side^^

Hello, Sorry i had completely forgotten about this topic. I was coming back to post about the same issue and realized i had already posted about it a long time ago. I'm trying to make the Hue lights listen to the desktop Hue Sync app. Basically, during daylight, i don't need f.lux to make my lights match the screen color. So i always have to disable the Hue lights in the menu. I was wondering if they was a hotkey or something that could do this. Another idea would be to not make the menu disappear every time we tick or untick a Hue light to use, to avoid re-opening the menu again everytime we switch on/off a light to use. I know a more radical solution would be to simply close f.lux, but i'd have to open it when it's getting darker.

Here is a screen cap of my options and driver info: https://mega.nz/file/q1czAQjA#m0EuCGtM7bjfQbr4AyhsEdnX48GHMl1ZZc-dKfUZp8g I on a Razor Blade 17 laptop with no extra monitors or virtual desktops.

+1 to providing this behind a warning. I'm mostly interested in having brightness adjustment; software color adjustment works fine. It could be reasonable to quantize the brightness steps, limiting the number of writes to some limit, e.g. 10 per day. I wouldn't mind if my monitor died after 10,000 days.

Nope. I need to sleep the same way and the only thing you can do is adjust f.lux manually. What I do is, I keep the Registry subkey deleted named "f.lux" from here: Computer\HKEY_CURRENT_USER\SOFTWARE\Microsoft\Windows\CurrentVersion\Run Each update to f.lux puts this subkey back. By deleting it, f.lux doesn't start with Windows. You see, I keep f.lux set to "Classic f.lux" so that I only have a Day and Night color temperature and I keep both set to 800K. This way, when I'm ready for 800K, I just launch f.lux. The next time I wake up, I turn my computer on and f.lux doesn't launch. It's nice.

OK, I spoke too soon. It stopped working again tonight. Not sure why. The only relevant piece of information is that I restarted my computer earlier, but why would that make f.lux not work? The settings say it's working, but the color hasn't actually changed on my screen. I quit the app and restarted, and no difference. Anyway, here's the driver info: Intel Corporation 27.20.100.8935: Intel(R) UHD Graphics (20201028) NVIDIA 27.21.14.6280: NVIDIA GeForce GTX 1650 Ti (20210609) Fresco Logic 2.1.34054.0: Fresco Logic IDDCX Adapter (20171113) AOC 2343, 509 x 286mm, built 2012 Chromaticities: R=0.648438 0.338867 G=0.282227 0.602539 B=0.142578 0.070313 W=0.313477 0.329102 sRGB gamut: 92%, AdobeRGB gamut: 64% Generic PnP Monitor, 344 x 194mm, built 2018 Chromaticities: R=0.648438 0.344727 G=0.333984 0.616211 B=0.150391 0.057617 W=0.312500 0.328125 sRGB gamut: 83%, AdobeRGB gamut: 58% Unlimited gamma ramp=1, Internal ramp=0 Monitor 1 on Fresco Logic IDDCX Adapter Has VCGT profile=0, Gamma Ramp works=1 Windows Build: 19042.1237

@amerykanin Emailed you again

also one additional piece of info - it could be amd specific compatibility. i asked someone on the internet and they're using windows 10, nvidia's 1060 and 3080 and apparently those doesn't have the same lag issue as mine.

Thanks, enabling "Always use Windows internal color table" fixed the problem. I have not otherwise noticed a difference. Are there disadvantages to enabling that setting? Also, do you know if Microsoft is aware of the problem?

Hi - we have only noticed the issue on window create. That is, they should only steal focus one time. There are a few reasons we draw our own right now: We support Windows 7 (though this is less an issue over time) We draw animated results in the notifiers (for instance, while dimming) The interaction with native code and windows "modern" notifiers was a bit difficult when we wrote this (they live in two separate universes, or did at the time). For instance, at one point we were registered as a new "app" on every launch, and we filled up the SQL database Windows uses for managing notifiers with thousands of entries, all named "f.lux" - that was pretty upsetting for our beta testers. #3 was the immediate reason we took this out but it is probably easier to make it work right now.
