On the Settings > Functions tab, click Scripted Function > Download Scripted, then search for "Remove borders" and you'll see them

Hope that helps! ]]> https://www.displayfusion.com/Discussions/View/expand-windowed-application-to-fill-monitor-but-not-maximized/?ID=b903097c-fce4-42df-bfee-39d4c8394bcd#3 Tue, 05 Nov 2019 06:14:29 GMT Binary Fortress Software https://www.displayfusion.com/Discussions/View/expand-windowed-application-to-fill-monitor-but-not-maximized/?ID=b903097c-fce4-42df-bfee-39d4c8394bcd#3 DisplayFusion Thanks! This software still surprises me. Would there be a secret borderless window mode? ]]> https://www.displayfusion.com/Discussions/View/expand-windowed-application-to-fill-monitor-but-not-maximized/?ID=b903097c-fce4-42df-bfee-39d4c8394bcd#2 Mon, 04 Nov 2019 18:38:39 GMT Binary Fortress Software https://www.displayfusion.com/Discussions/View/expand-windowed-application-to-fill-monitor-but-not-maximized/?ID=b903097c-fce4-42df-bfee-39d4c8394bcd#2 DisplayFusion You can do that with a Custom Function, yep! Please see the attached screenshot for reference. You can add those on the Settings > Functions tab, by clicking Custom Function > New Custom Function.

One other thing you could try is enabling the "Ignore Full Screen Windows" option in the Settings > Advanced Settings window. That might help with the Start menu issue in full screen.

One issue is that some applications automatically go into fullscreen mode when maximized like Citrix's VDI.

Is there a function to make a windows application expand as large as possible to fill a monitor but without going into maximized mode? The manual way to do this is to draw each edge of the window to each edge of the monitor. This would be a workaround for the start menu problem. If this modified maximixed mode can be accessible via titlebar button and monitor-edge snapping and can be limited to the primary monitor, then this mode can seemlessly replace the normal maximize. ]]>
