If you tell me your host display topology (monitor resolutions and relative position), I can give you a better VMwareResolutionSet commandline to run. Which display that is depends on your host topology. So if you toggle to fullscreen with only two displays in the guest, we will put the full guest topology on one host display (both guest screen side by side, like you are describing). It sounds like you have three physical displays (Mac laptop builtin + 2 external displays). If you can set the modes, then you can see their layout in the single window. With these settings, your guest topology should not change when you toggle between single window and full screen mode. Then use the VMwareResolutionSet.exe binary installed with Tools. You can also try setting your screen resolutions manually, by setting the Full Screen preference to "Center the virtual machine in the screen", and Single Window preference to "Stretch the virtual machine in the window". (But it sounds like you already did, and it didn't help) If that still doesn't work, you can also try specifying these four config options together to override the monitor autodetect settings. Make sure your Fusion preference Display > Full Screen is set to "Resize the virtual machine to fit the screen", and toggle full screen.

This is the same as the VMX config option:

To use the second monitor, you should set the view setting View > "Use All Displays in Full Screen".
