Could you try a couple of things on the host machine?

• Update to DisplayFusion 9.0 Beta 4
• On the Settings > Compatibility tab, add a rule for C:\Windows\System32\vmconnect.exe, and in the rule, enable the "Disable Application Hooks" checkbox

I've attached the two files. I turned on logging and then next thing I did was enter the VM in "Use all my monitors" mode. So the timespan of the log should pretty much only cover that operation.

I also enabled logging for a moment inside the guest and did a quick "switch to next monitor" command on a window. It's attached as "Guest DisplayFusion.log" ]]> https://www.displayfusion.com/Discussions/View/display-fusion-conflict-with-hyper-v-full-screen-use-all-monitors-windows-10/?ID=2b17b1bf-4f42-4fcd-b8ed-8d769ff50e40#2 Fri, 22 Sep 2017 18:02:18 GMT Binary Fortress Software https://www.displayfusion.com/Discussions/View/display-fusion-conflict-with-hyper-v-full-screen-use-all-monitors-windows-10/?ID=2b17b1bf-4f42-4fcd-b8ed-8d769ff50e40#2 DisplayFusion Unfortunately there aren't any tricks that would get the guest to only use some of the monitors instead of 1, sorry

Regarding the other issues, could you send me a debug log? Here are the steps:

• On the DisplayFusion Settings > Troubleshooting tab, change the Logging drop-down to "L1: Log Minimal" and click Apply
• Launch the VM full screen connection and note the time so we'll know where to check in the log file
• Send us the DisplayFusion.log and DebugInfo.html files (can be found by clicking the Open Log button on the Troubleshooting tab)
• Disable debug logging after sending the log

My configuration is a laptop monitor and two external monitors. I develop inside a Hyper-V virtual machine hosted on my laptop. I tell the Hyper-V connection dialog to "Use all my monitors" and place it in Full Screen mode. I have DisplayFusion installed and running inside the VM. It works fine in there and all is well UNTIL I also run it on my host machine. When it's running there the guest VM's display gets all out of whack. The list of issues is long, but they don't size correctly, don't use full screen, move to other monitors, allow host task bar to continue to display, don't show guest taskbar, etc. Basically just a jumble.

I'd like to run DF on my host because of the multi taskbar features, etc. Unfortunately, at present, I have to keep it turned off in order to be able to work inside my VM.

Another thing while we're at it --what I'd *really* like to do is use DisplayFusion to allow me to run my VM on the two external monitors in a full screen mode as two monitors and leave my laptop screen displaying my host. Hyper-V doesn't support this based on everything I've been able to find --it's either all monitors in full screen, or 1 monitor non-maximized and stretched, but not practical to work in. If you have any DF trickery that will allow me to do it, please pass it along.

Below is system info from the DF Troubleshooting output taken inside my VM. Thank you.
