<![CDATA[Only Disable f.lux on The Monitor That Has Fullscreen App]]>Welp, here I go posting on this forum because there doesn't seem to be a discord server or anything... Lord knows how long it will take to get a response, if i even get one at all :/

Anyway, this is an extremely specific question about the "Disable f.lux on fullscreen" feature.

Is it possible for me to set up f.lux in such a way that when I fullscreen an app/run a game in fullscreen, only the monitor with the fullscreen app/game disables flux? It is an absolute chore having to manually disable f.lux for each individual monitor whenever I want to play a game/video in HDR with accurate colors and brightness.

Additionally, is it be possible to prevent flux from turning back on every time that fullscreen app or game loses focus? I have three monitors and f.lux gets enabled and disabled on all three when the fullscreen app is tabbed in and out of. This causes the blue light filter to toggle on and off as I work between monitors, which is infuriating.

Is this intended behavior? Are these bugs? I know it's possible to manually disable f.lux on only a specific monitor, so could it be implemented that the "Disable on fullscreen app" option only disables f.lux on the monitor will the fullscreen app? PLEASE??

I would greatly appreciate any responses (I'm begging here at this point)

@herf Yes, they support HDR. To be specific they are both an Acer Nitro 27".

Additionally, I am using Windows 11's Auto HDR setting. Which, to my understanding, changes a display to SDR if the content (or just games? That is all I see it with at least) does not support HDR.

Presumably some video content can trigger HDR mode (and some does not).

If so it says "Current color accuracy mode: Accurate", the check box for "Override to reference mode" is empty. Also, just in case it has any impact, I should mention that I have f.lux's "Always use Windows internal Color table" feature enabled because f.lux's recommended colors are disturbingly orange with HDR display settings.

Additionally, since I last posted I have noticed that my report may be application edge cases. I saw the behavior I reported while playing Against the Storm and watching something on Max.com (previously HBO Max). But since then I have experienced the proper expected behavior while playing other games and, contrary to the impression my initial post may have given, watching YouTube. So it could just be that Against the Storm and Max.com do weird things.

Can you look in NVIDIA's control panel and see if "reference mode" is checked?

Unfortunately, I don't know if it just started not working right or if I am just now noticing it. I built this computer three weeks ago and only just learned of and enabled HDR a few days ago.

On my previous system, f.lux would disable on individual screens that had a Borderless Window game running or a full-screened video player like YouTube. Now it just stays on, even if I turn the feature, or application, off and on again.

If driver info shows >1 display it will do per-monitor disable and otherwise no.

However, we prefer to be able to "see" this monitor info in order to calibrate to each display separately, so we would like to see it work 100% - but we can (+will) work around this for the disable feature though.

v4.133 has one more fix and is on the beta track today.

For validation sake, here is my driver info on 4.1.32 that now properly disables f.lux on a per monitor basis.

Interestingly it seems to only be showing 2 monitors, which is indeed more than the 1 it was showing on the previous version. However, it's correctly disabling f.lux on all three monitors, on a per monitor basis and that's all that matters to me. Thanks for your help and the fix, @herf.

Behavior on previous f.lux versions was only the monitor with the fullscreen app would disable. Now when a fullscreen app appears all the monitors get disabled.

This is possibly fixed in v4.132, which I have posted here:

https://justgetflux.com/flux-setup4-132.exe

Can anyone with this issue please post "driver info" again using 4.132? What we're looking for is that the number of monitor descriptions matches the number of connected monitors.

We may try to do it a different way for your machines, but the best fix would be to actually figure out where the monitor information went. ;)

For both of your machines, we have found the monitor info for just ONE monitor, but then there are multiple monitors connected. So we might not be seeing them as independent devices necessarily. Another difference is that our test machine has an Intel integrated adapter while these are both discrete GPUs.

Can you say how monitors 2-3-4-etc are connected, like which kind of cable? If it's HDMI which version?

We will do some more testing on Windows 11 / 23H2 today.

So you're saying the default behavior is for f.lux to be disabled and enabled on all connected displays when a fullscreen app loses or gains focus in windows? Because I would really hope there'd be a way to only have the "disable on fullscreen" option affect the display that actually has fullscreen content on it...
