Color Slider over multicast?

I have two screens running realdash set up for multicast. How can I use one screen to control the color of both?

Never tried that as Color Slider is still somewhat internal feature. I will make some tests if it works thru multicasting.

Awesome thanks! I can get the slider from screen A to move using screen B however the color remains unchanged until interacted with on screen A. Keep up the great work!
