Dual monitors, F.Lux affects one but not the other.
-
I have exactly the same problem.
-
I have this problem as well.... Almost. on mine, they are affected, but to different degrees.
Windows 10 on Dell E series Docking Station. the dock has 2 DVI ports.
Intel HD Graphics 5500 display adapter.I have 2 Dell 1707FP monitors. both are set identically (reset to factory defaults) the primary monitor is WAAY redder than the right monitor when f.lux is enabled.
when I disable f.lux, the monitors again have the same identical look. -

BUMPING as problem presists, and is also mentioned in these threads:https://justgetflux.com/forum/topic/231/windows-10-second-screen-doesn-t-change

https://justgetflux.com/forum/topic/328/windows-10-with-3-screens-one-screen-doesn-t-work-with-f-luxAsking again for an acknowledgment from devs?

I have the same problem. My Main monitor (connected through hdmi) is working excellent with f.lux. My secondary screen (connected through a hdmi with vga-adapter) however is not working with f.lux.
I heard it helps to 'mention' the admins so I'm just gonna type @lorna and hope for the best :)

@Chads F-Lux working on both screens tonight! No changes to PC that I'm aware of. Last GPU driver update was over 2 weeks ago. I'll post on any changes, otherwise consider the issue mysteriously resolved...
-
If you figure it out, let me know, because it's still doing it for me.
-
Two separate issues in this thread:
-
HDMI stopped working in Windows 10. This means all color controls are not working. LOTS of stuff changed in the Windows 10 driver model, and people online are saying NVIDIA has been slow to reach feature parity on Win10. I would expect this one to resolve in a future driver update.
-
Docking station troubles -- this sometimes involves DisplayLink (USB monitor) and currently there is no fix for this, since this adapter does not support color profiles.

@herf Thanks for responding herf. When F-Lux works, I love it.
Unfortunately after my "it works" post of last week, it reverted to its not working state the next time i used the monitor. I don't know why it began working, or why it stopped again.
So, regarding HDMI / F-Lux. Are you saying this is an Nvidia issue, and that I need to wait for a fix from them? Is F-Lux not working for all users with a combination of Nvidia drivers and HDMI output, or am I just unlucky?
-
[@herf Okay, so I just went into Nvidia control panel / Set up multiple displays, then clicked on "Clone source", and switched it from screen 1 to screen 2.
The screen with F-Lux working on it switched from my Display Port monitor to my HDMI one. So instead of F-Lux on the DP and not on the HDMI, it was the other way round.
I have disconnected the DP cable, and F-Lux works on the HDMI screen, then reconnected the DP and it stops on the HDMI. Plugging or unplugging the HDMI screen does not affect Flux on the DP screen.
This would suggest that it can and will work on Win10/Nvidia with HDMI, and one of either DP or HDMI, but not both at the same time.
Not sure if related, but I have also noticed that the "Adjust video colour settings" are greyed out for the monitor that F-Lux does not work on, whether that's the DP or the HDMI.

I am having the same problem. f.lux is working on my primary monitor, but not on my secondary monitor.
Windows 8.1 Enterprise, 64-bit
NVIDIA GeForce GTX 745 with driver version 358.91 (up-to-date)
2 identical Dell monitors connected directly to desktop: primary connected via DVI, secondary connected via VGA -
I'm having the same problem on my dual monitor setup, it's only working on my main monitor and not the 2nd.
Windows 10.0 (build 10240)
Nvidia GTX780 v358.91
2 monitors connected via DVI-D (main) VGA (2nd) -
I'm also having trouble with my dual monitor setup, however, my second monitor is the one that works all the time (HDMI) and my first (display port) will not work with flux until I manually start the program.
the issue arises when the computer has been asleep or the scrensaver has been on. so far it's consistent that it's always the display port monitor not working after sleep/screensaver.
I am also using an AMD GPU.
edit - the DP monitor is also a 144hz monitor where the HDMI is your normal 60hz
-
Mine reverted to working about 5 days ago.
-
Our Surface Pro started not working with "mirror" mode (it's all Intel, not NVIDIA) - if you use "extend" mode it works fine.
I think we're just getting weekly driver updates for Windows 10 right now, and everything will settle down eventually.
-
I'm having the problem of Flux only working on my Main display and not on my second monitor, but I am running Windows 7 and am not using HDMI or any docking station so I don't understand why this would be happening.
Windows 7 Ultimate SP1
NVIDIA GeForce GT610 v359.00
2 monitors connected via Dual Link DVI-D (Main) and VGA (2nd) -
Hello,
Same issue here, windows 10, nvidia, using my screens as duplicates (1 hdmi, 1 dvi), it's only working when I switch to single monitor :(
-
Just chiming in with the same issue, monitor one(flux working) on displayport, monitor two(no flux) on hdmi -- via radeon r390x. If there's anything I can provide via dump log, feel free to let me know!
-
Same issue! I have three monitors, 2 work with Flux, the other one doesn't.
Windows 10, my third monitor is connected via a USB display adapter.
-
@Andrew-Tullsen I think @herf already provided an answer for that iussue: "Docking station troubles -- this sometimes involves DisplayLink (USB monitor) and currently there is no fix for this, since this adapter does not support color profiles."
-
So old topic... I just wondering that f.lux will never support multiple monitors. Anyone knows an alternative?
