I know you guys already give us a way for display video on Multiple screen.like : http://support.visioforge.com/knowledgebase/articles/189619-multiple-screens-for-wpf-controlsMultiple screens for WPF controls
But the problem is because it's just a picture, it only use CPU power, we can't use any Hardware Acceleration. or other about video render.
So can you guys add some new api can use Hardware Acceleration when use Multiple screen mode?
For example We can use MediaElement1 display video, can we let the another MediaElement2 copy the MediaElement1(Hardware Acceleration too , not only just a picture)
if it's just picture, it will use a lot CPU, if the window more big, use CPU more lot.

If you have ideas how to make it faster than WriteableBitmap you can implement in on your side. All frames comes in OnVideoFrameBuffer.

You can create your own DirectShow graph with WPF media kit and push frames from OnVideoFrameBuffer event, but we have tried WPF Media Kit usage and speed is very unstable on different PC's. WriteableBitmap fast and stable.
