Hello Guys,

I googled so much but I did not find any solution.

I created a app with C# WPF. It is creating UI from a dashboard. Dashboard is in first desktop, UI is in the second desktop. My windows extended and I am showing UI in external monitor.

UI's background is green and it contains some different graphics for example orange. I would like change green color to alpha (transparent) and stream UI over HDMI in real time for showing in out sources.

Shortly, I would like apply Chroma Key for HDMI real time for sports tv broadcast graphics. Is it possible or not?

Thank you in advance.
