I got a Sony 4k tv and a old samsung 1080p tv hook up to a splitter than to my pc so need to change between 4k and 1080p resolution. The monitor configuration only allow me to change desktop resolution not active signal resolution. The only way i can do this with nvidia control panel.

I can change Active signal resolution via this window (Attached below)but not in the Display setting.
I found this guide that help me but still i can't used the displayfusion Monitor Configuration profile so no more easy switch
between monitor.

Hello,

just wanted to point out that I've got the same issue using Display Fusion 9.5 Beta 1
(previous steam downloaded version also has the same issue)

When changing resolution with DF 9.5b1, Active Resolution Signal is 4k.
Whereas with windows or Nvidia control panel it is

This issue is blocking when you need to send a FHD signal :
(HDMI cable length or target device hdmi limitation)

Thanks for your help.

Same problem here, when the monitor that i have configure out in the profile to be in 1080p, (i also have an HDMI cable length that not permits 4K) DF makes the active signal in 4k...

if u fix this i'll buy a license 1 second after that.

Just wanted to say I'm having the same issue. Whether Display Fusion is set to clone the 4k display @ 1080p with another monitor, or if it's set to extend alongside my other monitors, it doesn't matter what I have the resolution set to; it doesn't work. I can get it if I set it to only output to the 4k monitor and nothing else, but that is not ideal. Someone higher up was speculating that active signal resolution might be an NVIDIA thing, and I just wanted to clarify that it's not. If you open Windows display settings, and scroll down to advanced display settings, you'll see it's a part of Windows. In the attached screenshot, I was able to make this method work on my gtx770, but after it fried and I replaced it with an rtx2070, I haven't been able to get it going since. When you click apply in the box on the screenshot, the cursor spins for a few seconds, but otherwise nothing happens, and my desktop resolution is set to 1080p with a 4k active signal resolution, with no picture on the screen. Also, I've noticed that it gets really wonky with 30hz vs 60hz; it keeps trying to drop down to 30hz when you try to set it, even though the monitor is capable of 60hz, and coincidentally it appears to put a very heavy load on explorer.exe whenever it is attempting to configure the displays. I hope this info helps you track down whatever the cause is. Here are my specs as well:

DF 9.5
i7 4770k
32GB RAM
MSI RTX2070
6x viewsonic 27" 1080p monitors (top 3 from IGFX, bottom 3 from RTX2070)
1x TCL 65" Roku TV (from RTX2070 and (ideally, if you guys can get this fixed) cloned with bottom middle monitor)

Haven't seen any updates on this post since May; wanted to make sure it doesn't die before it gets resolved. Thanks guys!

Dead link? It gives a 404 error

Ah, never mind. your link was for ~~~.exe.exe took out the extra .exe and it downloads now. Thanks!

I have this same problem using the Steam version of DF, and never thought to bring it to your attention. lol

The only place I seem to be able to change the active signal resolution is in the NVidia Control Panel. Windows display settings also seem to only change the internal resolution, upscaling it to 4k... at least in every attempt I've personally had.

I put my 4k in 1080p for various reasons (cloning, gaming, streaming, etc), and while it can natively support 1080p, both Windows settings, and DF refuse to use true 1080p.

Since I use the steam version, how would I go about testing this beta? do I need to uninstall the steam version, then install this beta?

Thanks! I tested by setting to true 1080p, and saving. When I changed to 4k, then changed back to 1080p, it was still upscaled.

This happened both with an overwrite, and a new save. Is there an option that I'm supposed to change first?

When I use Windows settings, (which don't change the active resolution) yes. When I use NVidia (which i use to force active display resolution) no.

When forced with NVidia, saved, and then returned to later, it still has the 4k active display resolution. Still has to be overridden by NVidia to get the display to change to real 1080p.

Just to add - this is definitely not Nvidia specific. I am using an AMD graphics card and am having the exact same issue.

My circumstances: I have my PC connected to a 4K TV using a Wyrestorm HDBaseT extender. The HDBaseT extender / cables simply aren't high enough quality to run 4K flawlessly (I get occasional snow and sound cutting out), so I need to stick with 1080p. However when switching to a profile with this display active at 1080p, the Active Signal Resolution is set to 4K - which has the same issues as running true 4K.



This works for me too.

I have tried DisplayFusion 9.6 Beta 5 and this has not fixed it unfortunately.

I set the adapter settings correctly in Windows so that both the desktop resolution and the Active Signal Resolution were 1080p. I saved this as a new Monitor Profile. I swapped to to another profile/screen and then swapped to the new profile. The desktop resolution was then 1080p but the Active Signal Resolution was now 4K again - same problem as with the DisplayFusion 9.5.

I tried this a couple of times and the result was the same.

Please see attached troubleshooting info.

In these logs the new monitor profile (created when the Windows adapter settings were set to 1080p) is named "Test". I created the logs after switching back to this profile and finding the ASR was set to 4K.

Just to add that I've found a SuperUser post that references a third party utility that sucessfully saves and restores monitor settings from a file including the Active Signal Resolution. I've tested this and it does indeed work.

If these guys can figure it out, then hopefully DisplayFusion can?

I hope it's not against the rules for me to link this: https://superuser.com/a/1470967

The way to change the active signal resolution in Windows 10 is as follows.

Right-clicking the desktop, and choosing "Display Properties", and changing the display resolution in this window doesn't work. Instead, scroll further down in this window (down toward the bottom) and click "Advanced display setting". Now, on this new page/window, click "Display adapter properties", and a new window will open. On the "Adapter" tab, click the button "List All Modes", and a new window will open again. In this new window, scroll and click the resolution you want, then click ok (that window will close). Now, on the previous window, click apply. This will change the active signal resolution as well.

One glitch to be aware of... This happened to me... If you've already tried changing the resolution from 4k (3840x2160) to 1920x1080 (for example) the way I mentioned above that doesn't work, then when you first load up the window that lists all the display modes in the adapter settings, it will show 1920x1080 (or whatever resolution you chose in the normal display properties window). However, in order to make it change the active resolution to this, you will need to choose a differnt resolution from the "List All Modes" window, apply it, then go back into the "List All Modes" window, choose the resolution you want, and apply it. Now, the active signal resolution will change as well. Hopefully that makes sense, seems like a long description to describe a simple problem... lol

My recommendation is to never change the resolution in the normal display properties window. Instead, you should always just change the resolution through the Display Adapter properties Window through the advanced display settings, and the desktop resolution and active signal resolution will both always change and be in sync.

Hopefully this is helpful to someone.

Nicely done! This appears to have resolved the issue!

NVidia users can get the correct active resolution by changing the resolution, then set scaling to be done on display, and enable override in the nvidia control panel

I can confirm this is now working for me with my AMD graphics card.

Though confusingly I'm not on 9.6.2 Beta 1 as was requested; it's working for me on 9.6.1 stable.

(I also didn't have to recreate my monitor profiles.)

Details don't matter though; in any case I'm happy . Thanks Keith Lammers!

Amazing. it is working. Thank you Sir.

This doesn't seem to be working anymore in Windows 10, using the Steam version of DF v10.1.2. This is a fairly fresh install of Windows 10, so not sure if there is something I missed.

The issue persists in 10.0, but not 9.9. For both tests, I had my display in 4k at the time of install.

for 10.0, I used the existing "4k" profile as a starting point, and created "1080ptest" after switching configurations with the "List all modes" method.

in 9.9, I created "4ktest", switched using "List all modes" method, and created "1080ptest2"

To test, I used DF to switch to "4k" then back to the test resolution in both tests.

Can I safely upgrade back to the latest via DF's update prompt from 9.9?

Edit: I reinstalled 10.0 then updated via the update prompt. When loading "1080ptest2" (created with 9.9) from "4k" it worked as intended. This means upgrades from 9.9 to latest will likely not have this problem, if they used their original 9.9 monitor profiles after upgrading, instead of creating new ones.

just checking to see if there's any update on this?

The beta didn't seem to make a difference. I deleted one of the profiles that had the 4k display at 1080p. After that, I made the changes that had the active signal resolution to also be 1080p.

I saved, changed to 4k, and then back. Active signal resolution stayed at 4k
