Monitor Configuration unable to apply certain modes

I have an HDMI projector which does 4k 60Hz, and 1920x1080 "game mode" at 240Hz. I was hoping to be able to switch between these using monitor profiles, but it's not setting the refresh rate correctly in the 1080 profile.

Through windows settings or DisplayFusion, I can set the projector to the following 1080p modes, up to 60Hz:
Desktop mode:1920x1080,23.98Hz Active signal mode:3840x2160,23.98Hz
\[...\]
Desktop mode:1920x1080,60Hz Active signal mode:3840x2160,60Hz
The following can be set through windows settings, but attempting to apply them through DisplayFusion results in it setting this instead.
Desktop mode:1920x1080,119.88Hz Active signal mode:1920x1080,119.88Hz
Desktop mode:1920x1080,120Hz Active signal mode:1920x1080,120Hz
Desktop mode:1920x1080,239.76Hz Active signal mode:1920x1080,239.76Hz

It seems this projector supports higher refresh rates and lower latency on a 1920x1080 active signal, and all other resolutions are on top of a 3840x2160 active signal. I saved a profile with the desired 240Hz mode set through windows, and while it doesnt apply it correctly, it does show 'Detected Profile' when the refresh rate is set externally from DisplayFusion. I was on 10.0 and just installed 10.1-Beta 4, but that did not change the behaviour.

Can you try this version and see if it works? https://www.binaryfortress.com/Data/Download/?DownloadID=e4469990-f9c9-4460-9e94-3b66de577eb7&Log=0

Thanks for the quick response! Refresh rate gets updated correctly with this version. I see that

MonitorConfig

doesn't the store

ActiveSize

data that

MonitorProfiles

does.
On the other hand,

MonitorProfiles

doesn't seem to support

DpiScalingPercent

, which I would like to be able to set as well inside the same profile.

While the version you linked me does not see the previously created

MonitorConfig

profiles, I can switch back to 10.0 or 10.1-Beta4 and still load resolution and refresh rate from the

MonitorProfiles

I saved in 10.0-Beta17c, and load the

MonitorConfig

to set the scaling.

Attached the reg keys in case it helps.

Yeah that version uses old monitor code that doesn't support the DPI changing. We are aware of some similar issues and we have this on our list to look into. We'll let you know if we need any other info.

We've released a new beta with some further changes. Can you update, recreate your profiles, and see if the issue persists?

I'd tried Beta 6 about a week ago, so thanks for getting back to me, cause otherwise i might not have checked back for a while.

Beta 7 works, thanks for all your hard work! I can now have one profile that is

1080@240Hz 100% DPI

and another that is

4K@60Hz 175% DPI

, and applying them does set all those values correctly. It also looks like the "detected profile" seeming to take both refresh rate and DPI into account before claiming a match!

I did find what seems to be a related race condition with DisplayFusion's taskbar, but I've just switched back to using the windows taskbar, as it doesnt seem to have any issues with DPI switching.

Normally, I see the DisplayFusion taskbar disappear and relaunch on my other monitor while the resolution changes on the other, but about half of the time, when switching from the

4k 175% DPI

to the

1080 100% DPI

(n=20ish), the DisplayFusion Taskbar doesn't relaunch and the monitor with the changed DPI will still have the old DPI on the taskbar. Restarting DisplayFusion after switching does fix this, as does exiting DisplayFusion, and then swithing profiles with

DisplayFusionCommand

, the following options didn't quite work as i'd hoped:

Code
Copy
Select All

PS C:\Program Files\DisplayFusion> .\DisplayFusionCommand -closeall -and .\DisplayFusionCommand -monitorloadprofile "240Hz Projector"
C:\Program Files\DisplayFusion>DisplayFusionCommand -closeall && DisplayFusionCommand -monitorloadprofile "240Hz Projector"
DisplayFusionCommand -closeall -monitorloadprofile "240Hz Projector"

Seems like I could do this in general, but would have add a sleep, since

-closeall

doesnt wait for success before returning

I forgot to post here again, but I found the "Scripted Functions" feature, so I worked around it with this:

Code
Copy
Select All

if (BFS.DisplayFusion.LoadMonitorProfile(newProfileName))
{
    BFS.DisplayFusion.RunFunctionAndWait("Toggle Multi-Monitor Taskbar");
    BFS.DisplayFusion.RunFunction("Toggle Multi-Monitor Taskbar");
}

It takes a couple seconds longer to switch profiles, but fixes the taskbar scaling issues in the same button press.

Glad to hear it's fixed up!

I've added that DPI issue to our list to look into, we'll let you know if we need any other info there.

Thanks!

We've released a new beta that might fix up that DPI issue, can you try it out and let me know if the issue persists?

Thanks so much, switching between these profiles using a function button on the taskbar no longer requires a forced toggle of the taskbars afterwards!

I noticed a minor transient bug on the DPI switching if I switched profiles with the confirmation dialog enabled, in that it seems to freeze the taskbar reloading at whatever state it's at until you click confirm, so while the confirm dialog is up, sometimes there is no taskbar on the monitor which just switched DPI, and sometimes it's the old DPI (this screenshot attached), and sometimes it's as expected.
This ALWAYS fixes itself after clicking confirm, so it seems really minor, and I disabled the confirmation dialog for my function button that switches between them, so it's not bothering me, but thought you might still want to know.
It also doesn't look like it always gets the DPI set "back" correctly if you revert on the confirm dialog.

That said, as none of these edge cases affect my use case, feel free to consider my issue fully solved with 10.1 Beta 8

Glad to hear it's fixed!

We can't seem to reproduce that loading issue here, but if we're able to in the future we'll take a look into it and see if we can fix it up.

Thanks!
