Forums -> UltraMon™ SDK -> Mirroring single application window

Is it possible with the UltraMon SDK to mirror an application window? For example, a windows form opens on a secondary monitor with a separate window on the primary monitor that reflects the changes to the original window.

Not with the SDK, but you could do this with UltraMon and the MirrorMon add-on.

Great! Thank you for the response. I'll take a look at it.

Not all applications can be mirrored using MirrorMon. Maxthon 5 or Mozilla Firefox are mirrored. But for example Google Chrome or CentBrowser and some others mirror black screen. Win10 x64, UltraMon 3.4.1 x64. There is a solution? Thanks.

In UltraMon, the "Mirroring" menu also does not work. It also doesn't work with the "disable video overlays" setting.

By the way, the Microsoft Edge (version 86.0.622.69 x64) browser is not mirrored either.

I'm seeing that as well with Edge, at the moment I don't see a solution except mirroring the whole monitor instead of only a specific window.

UltraMon and MirrorMon already use different methods to mirror only a window, and both don't work with Edge.

Very sorry(

Also "mirroring - part of the desktop" does not work. Can't "grab the crosshair to select an area". This can only be done through the command-line arguments of the MirrorMon.

This works fine for me, position the mouse over the crosshair, then press and hold the left mouse button, then move the crosshair to the top-right corner of the area you want to mirror and press and hold the right mouse button as well to select the area.
