I am getting the following error, when trying to apply a 3 monitor profile, after one my monitor becomes undetected after waking up from sleep:

An error has occurred while applying your new Monitor configuration.
Please check your settings and try again.
Error: Failed to call SetDisplayConfig. [HR: 87]

Setup:
Display Fusion 9.4.3 (steam)
AMD Software Version 17.12.2
Windows 10 (64bit)
4K main monitor, 2 1920x1200 monitors in portrait mode on either side

Steps to reproduce:
1. Have 3 monitor profile loaded.
2. Put the computer to sleep.
3. Monitors turn itself off powersave timeout.
4. Wake up computer
- At this point my 4k monitor has no video signal, and I see only two active monitors in windows.
5. Apply 3 monitor profile and get above generic error.
- If I got into regular Windows Display settings, and click on Detect, my main monitor comes back fine. At that point, switching profiles stops giving errors.

Note that my 4K monitor is a TV and I have the EID HDMI pin disabled on it, so that it won't normally disappear from windows when it goes to sleep.

I also have switching to 3 monitor profile setup as trigger for when the computer comes out of sleep. I don't see the error from that trigger, and can't really tell if the trigger is even activating.

Is there any way for Display Fusion to mimic pressing on the Windows Detect Displays button? I see previous posts about the monitor profile apply error, but they are already fixed or are blamed on the driver. However, if Windows can detect the display just fine by pressing a button, I am hoping Display Fusion can workound the problem it has now.

DisplayFusion can't currently trigger a detection like the Detect button does in the Windows display settings, but we do have an open request for this. If we're able to add it in a future version, we'll be sure to let you know.

Thanks!
