Single Monitor Restriction for a Dual Monitor Setup
I would like to see this feature as well. I have my TV and my PC monitor calibrated as closely as is possible without owning actual calibration equipment and they're basically indistinguishable as far as color when in normal "daytime" mode.
The moment f.lux kicks over to night mode what looks just right on the PC monitor is horribly warm like a dimmed incandescent light bulb on the TV.
I'd be fine actually with just being able to choose a different target color temperature per display rather than turning it off entirely. Frankly I'd prefer this so I could still get the benefits of using it on my TV and just fix it so it looks right.
@herf Hi. Just found f.lux two nights ago. so far mostly good, but like many here I have a dual monitor setup (monitor 1 is my TV, using a DVI-to-HDMI adaptor and monitor 2 is a standard DVI monitor on the same video card).
I mostly use Plex Home Theater for watching "TV" but also vlc and occasionally a browser window (Netflix, Hulu, Youtube, Slingplayer. etc.)
For my purposes, per application vs. per screen are pretty much the same since I mostly use these apps full screen on the TV.
Thanks, if this can be made to happen. If not, disabling for an hour or so does work.
Made an account just to agree to this! F.lux is already invaluable to me! I would LOVE an option to make it only work on one monitor for a while. Sometimes I will be playing a game while the other monitor is doing something else. I would like it so main monitor is unaffected. I would support this so hard!
Would love this feature!
I am currently running 4 screens, 2 at the bottom and 2 on top. The screens on top get somewhat unreadable when flux turns on(due to the viewing angle).
Just being able to turn certain screens on/off would be amazing!
I would also like to have flux on 2 monitors with two different settings. I have a new monitor which is very bright and an old one which has an unusual warm colour. If I have a good setting on my main monitor the old one looks very orange.
I also signed up to say how excellent this would be. Have a central PC feeding a family room TV and a bedroom monitor. My wife and are often on different sleep cycles due to work, it'd be wonderful for the bedroom monitor to be the only one affected by f.lux.
I'd love separate settings for each monitor too, I use my primary monitor for Facebook/Reddit etc so I really appreciate the dim tone, however I use my second monitor for YouTube and Netflix and really messes with the colours. Would love to set F.lux to only activate on my primary monitor until told otherwise, or at all.

I would really like it to be per screen. I've scoured the net looking for an app that will dim one or the other but not both.
I have a laptop hooked up to the TV via hdmi, so we turn all the lights off, settle down to watch a film on the TV but the laptop screen is sat there glaring away on the side.
We use flux on the wifes system which is a standalone and its a great util but can't use it on mine or the film we're watching goes dark, yes we can turn it off but then the laptop is bright.
To be able to dim the laptop but not the TV would be awesome & yes we use the laptop to play stuff just about every night
Many thanks in advance
You can set the laptop to "Do Nothing" when you close the lid on both battery power and A/C. You can have 3+ power profiles on Windows 7 as well, to swap to what you want. So you can then have the screen off, not wasting power.

I think it'd be really helpful to disable flux on 1 monitor (and even better if you could disable it on specific monitors based on what apps are running). I tend to just close f.lux when I'm running photoshop/playing games and forget to turn it back on...

I'm new to F.lux and loving it! However, USB support for dual/triple monitors would be so greatly appreciated! Please pass on these multiple requests for it.
I'd love the "per monitor" option as well. My Cintiq is set up as a second monitor and it "blinks" or "flashes" every 5-10 seconds as f.lux works it's magic. I disable it whenever I'm in Photoshop but it'd be nice to still have f.lux running on my other monitor all the time rather than blasting my with blue/white light while I paint ;) Having said that, thanks for such an awesome product!
BUMP. Would love to have this feature as well. My laptop monitor is for work and web, but the external monitor is 95% displaying video or working on photoshop. I have absolutely no need for f.lux on the external monitor.

The support over USB would help a lot of people out. I currently use an all-in-one which has no standard video outputs. This forces me to use a USB adapter and since I use this rig for some gaming but mostly intensive reading/college work I need my second screen to not burn my retinas as I try to read pages on pages of text. Thank you for all your support f.lux team!!!

Registered just to give weight to this. I would like f.lux to be able to differentiate the dimness between monitors. I'm using 1-4 screens depending on what I'm doing. One of them is a TV and the rest three are monitors of various ages and dimnesses. The most useful feature for me would be the ability to dim all but the TV but I'd have use for individual settings to balance the colors of my monitors as well. Other than that, I love f.lux.
This simply has to happen. Many of us have dual purpose setups. I have a screen strictly for sports viewing that looks disgusting/dull with flux enabled. But of course if I disable flux then my other IPS panel burns my eyes to a crisp. I think the needs are obvious here so hopefully this is something easily implemented. Otherwise love the app thank you for saving my eyes!
I'd also like to see this as a feature in a future update. The TV I use with my laptop looks horrible with flux enabled with any settings, and I'd rather be blinded by the (usually lack of) white on the TV while keeping the flux correction on the main laptop screen..
Flux has improved my life a lot. It is truly a great software. At home it works great, because I have dual identical monitor. However, at work it causes me problems. My laptop looks great at 2800k, while my actual monitor looks great at 3200k. I truly hope there is a way for me to set my laptop display at 2800k, while leaving my hdmi monitor at 3200k.
Personally I would prefercompletely independent settings for each monitor, there are several reasons for that:
- my main monitor is color-calibrated and at least some applications I work with have a dark color theme so leaving it unaffected by f.lux during the day is useful
- when watching movies at night on the same monitor movie mode would be useful
- movie mode on the other monitors otoh is too bright, distracting from the movie, I would prefer if I could switch the secondary ones to darkroom mode
- one of my monitors is fairly old and somewhat faded, it responds differently to dimming or lowering the color temperature in ways that cannot easily be compensated with monitor settings. independent settings would make it possible to match the other monitors better in overall perceived brightness.
Also registered to say that a per monitor flux restriction would be very helpful. I use one monitor for gaming/tv/movies and one for general purpose uses. I would love to have one monitor on and one off.
Just googled how to do it with f.lux only to land here.
Like most of the above, I have webpage/word document/work on one screen that is usually blindly bright while I watch a movie or play a game on another, and it gets a bit annoying to have to choose between f.lux and colours looking right in a movie/game.
Would love to see this feature added.
I believe a per app feature would be hard to do, over just disabling f.lux from controlling selected monitors.
I came here to upvote the rest. A per app and/or per screen feature would be awesome. And it has been a year or two now that I am looking for this!
Agreed, this should be on the dev list!
just registered to vote this up, i have to monitors, one new one that is already has a built setting that is easy on eyes, but my older monitor doesnt, which I would love to use f.lux with, I have already been using this with my laptop and it helps so much. I really hope you consider adding this feature to disable a second screen.
Registered to bump this up.
I have the same uses cases has the other people,
- Laptop screen with f.lux + TV without it,
- Laptop screen with f.lux + Old monitor without it
- 3 monitor setup, middle monitor without f.lux when gaming
I guess a per app setting would cover most of the use cases for the majority of people.
In my case, I would prefer a per monitor setting but with a per app setting, I could workaround this without any problem.
Thanks for the good work guys !
Forget any updates at this point. The app hasn't seem any updates for more then a year and likely never will. I've contacted another developer on a similar app and they said that it's highly complicated to make it work separately on multiple monitors. I understand this is freeware so this is what you get.
There are plenty of alternatives out there but I haven't tried them all but so far, the 3-4 I've tried does not have this feature as well. I'm not a developer so I have no idea the technical aspects of making separate settings but I would guess it's a lot of work and hence why many other similar programs don't have this feature as well.

@turbocomppro I'll tell you it feels just awful to read comments like yours while we are working to get good, solid, feature rich updates out to the world.
@lorna ignore that guy. is your team working on this feature? with my setup where I work and watch movies on separate monitors on the same machine would love to have this.
I just downloaded your application and it is a very good improvement. I am using a similar app on my android device.
I am also voting for having a dual monitor setup. I work at home and use my laptop 17" display and my 27" Benq display. Sometimes I would like to have only the laptop display changed and sometimes both monitors to be changed by f.lux.
I will contribute to f.lux even if this feature is not implemented, but I will contribute again when it is implemented.
Also registered to add my vote for independent settings on dual displays. I like to stream music visualizers & videos via HDMI from my laptop to my TV while I write. It'd be great to have the option to disable or use movie mode on the big display several feet away while f.lux still does its usual thing on the display closest to my eyes.
Adding yet another voice to the chorus here. I have a Mac Mini that drives a monitor for iTunes and web-browsing, and also a projector which is our living-room "TV". I just discovered f.lux and I love, love, love it on all of my computers, and I'd love to use it to control the color of the Mini's monitor, without impacting the color of the projector.
Unfortunately, I can't use the per-app interface as the two apps I most often use on the monitor to control music and web-browsing--iTunes and Chrome--are also the same two apps I'm likely to use to play media on the projector.
Bumping this up. I would love this when watching videos on one screen and browsing on the other screen.
i also just registered to reply to this.
+1 for adding multi monitor support to have seperate options for each monitor.. i would even pay for it if this was done.
up till now both my monitors(built in monitor for laptop, and external) had way too much blue, and needed flux on both of them.
now with my new BENQ eyecare monitor, i only need flux on my main screen (laptop screen) and if i run it on both monitors it ruins the BENQ external monitors good view.
Same here, i registered just to add my vote. As I work a lot on a stage and spend a lot of time in the dark doing video projections, I'd like to have Flux on my monitors but not on the video projectors I use at the same time. It would be much much less tiring for my eyes.
I just signed up to bump this thread. I also want the ability to use my first monitor with flux, and my second screen (which happens to be my Samsung TV connected via HDMI) without flux. I hope this feature can be included ASAP!
...also, I can see there are over 54K views on this thread. Clearly there is a demand for a solution here.
I'd like to have an option for flux to run on a per screen basis. I'd like my full screen games to be clear and colour accurate while youtube or anything on my second monitor is still easy on the eyes at night. If I disable flux for rocket league, then the other monitor is blinding while im playing. Also a lot of colour changes during alt tabs.
Jesus, why is this not a feature already?
I have two screens, and the one has a blue-light glare, whereas the other one has warmer colours. I need to use Flux on the one with the blue light, but that turns the other screen almost brown in comparison. Settings per screen shoul really be a thing.
I use two monitors and love f.lux but often can't use it as I create colour sensitive artwork.
Being able to disable f.lux on my primary monitor but keep it on my secondary would be truly amazing.
However, I did notice that when I played a certain game (Starcraft 2) that f.lux was disabled on the one monitor only(happy accident)!
It would be equally amazing to be able to have a control option where you can tell f.lux disable itself when a certain program appears.
I understand since it's a free program you can't go full blown dev on it, however, these are features I'd happily pay for.
One of my monitor is an e-ink display, so when flux is enabled, the eink monitor is covered with a grey background. I have to disable flux to use the eink display
would love to see this feature to be added into f.lux. Also, this is the feature i'd be happy to pay for

@frankang that is a new case for us, thanks - a reason for sure a good reason to do this.
To sum up how we're thinking about the other cases, there are basically two:
- "My monitors aren't calibrated and I want f.lux to calibrate them."
- We might add color calibration controls in the future, but this isn't what f.lux does right now. Any ICM file with a VCGT tag will be read and loaded by f.lux, and this is still by far the best way to calibrate. Other utilities can make this kind of profile. In any case, disabling f.lux for one display is not a good way to make the displays look the same.
- "I usually display dark content (like movies or even photoshop) on one display and bright content (like webpages) on another."
- We think f.lux should be smart enough to solve this automatically, without having to assign monitors to fixed roles, but we have more to do here, and it's an important case. And yes some people DO have external TVs that always do the same thing.
For #2 we have added "disable for fullscreen apps" that covers more than half of the cases people have mentioned, but there is more to do here, and our goal is to make it automatic and configurable.
@herf my previous issue with "disable for fullscreen apps" is that it would disable flux on both monitors. But it doesnt seem to be an issue anymore. Does flux need to be continually updated to support new fullscreen apps properly, or was it likely a one-time issue?

@DudeWithTheNose as far as I know, the Windows version of the feature has always worked this way. Maybe an early version had some bugs...
Currently, if I set to disable for full screen apps or a specific app it does it to both monitors.
Can you just include an option to run f.lux on the secondary monitor only? That would be an easy solution.
Really like f.lux but find that I can't use it most of the time as i'm working in an app that requires me to see proper colours.
I would like to add that most display drivers do provide color adjustments to individual monitors. Simply lower the Blue color of the desired display will results in similar a effect as f.lux.
Once you get the desired effect, save it as a profile and activate it whenever you need.
Of course, you do have to do it manually but at least something is better then nothing.
I made an account just to say I 66th this, I have a secondary monitor (aka tv) that I'm usually playing videos on while I work on my main screen, If I could permanently disable for my secondary screen that would be amazing
As with @ezhila I came to 67th this, when i play games on my primary monitor I often have teamspeak up, but i like to play in windowed (borderless) mode, so that I can still see the game when I'm on teamspeak or looking stats up on the internet. I've taken to disabling f.lux, but teamspeak and the web are both dazlingly bright, but the game doesn't look right with f.lux on.
(Love f.lux, been using it for a year and a half now, it's great!)
Keep up the good work!
My main gaming monitor has a built in blue light reduction that I like to use, but my other 2 don't so it would be awesome if f.lux could only be active on those.

So here is the thing.
LCDs, LEDs, OLEDs, etc are all terrible for your eyes and this is why f.lux exist. the next step after f.lux is already being taken by the likes of Eink and other manufactures.
I use that monitor for programming, writing, reading, pretty much everything where I do not required syntax highlighting or watching movies. But when you use f.lux on these monitors it reduces the contrast to such a degree that the monitor is rendered unusable almost.
Implementing per monitor color switching would really help all of us who are switching to eink and other light independent monitors.
While we wait for a proper implementation, here is a dirty solution.
-Install Argyll and run in command prompt: dispwin -c -d 2
*2 should be the screen where you want to clear the LUT, it might be 1 or 2 depending on display assigned ID
-You should see how the f.lux blue filter LUT restores, that's because f.lux is constantly ticking/checking (btw it should be great to disable this). So instead of closing f.lux (it will restore the LUT), simply kill the process: taskkill /f /im flux.exe
To summarize, create a .BAT with the following code and execute at will:
taskkill /f /im flux.exe
ping localhost -n 2 >nul
dispwin -c -d 2
