Dual monitors, F.Lux affects one but not the other.
-
@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?
-
@trm99 As far as I gathered there is no alternative since it is not the programm thats the problem but the hardware :(

2 monitors connected via Dual Link DVI-D (Main) and VGA (2nd)Do you have the monitors in "mirror" (duplicate) mode, or "extended" so that you can use each screen independently of each other? I think extended mode may work, but mirror doesn't seem to. That's what @herf said for the Microsoft Surface, but that may not be the case for Nvidia hardware, as the tablet they were discussing is all Intel graphics based.

Worked fine for me on:
Lenovo Thinkpad T430
Windows 7
Intel Graphics HD 4000
Laptop screen and VGAUpgraded to Windows 10 and Flux didn't work on the external monitor anymore. Quit Flux and ran as admin and we're back in business. Hope this helps someone.

I installed f.lux V3.12 and it worked only on a single monitor. When I installed it I was running on only a single screen via remote desktop (RDP). When I came to work and used the PC physically in the same room only one screen was affected by f.lux. I re-installed f.lux over the existing version and by doing this I found that both screens were then affected as expected.
I have not tried rebooting the machine yet as it's possible this might affect behaviour. If it reverts to working on only a single monitor I will repost to this forum.
-
I had the same problem but the problem seems to be solved at this moment.
As @MrSwadge mentioned above, I also re-installed f.lux over an existing software and then the filter is now applied on both monitors. -
@ReCrunch this came out yesterday which might be helpful for those using Display Link USB adapters http://www.displaylink.org/forum/showthread.php?p=82958#post82958

Just FYI for anyone coming here with Windows 7 and Intel HD Graphics 4600, I updated my display drivers and that did the trick immediately.
