I'm afraid this is not possible right now using a *single* draw call, since you won't be able to position the 'right' frame correctly. I've added a config (test.eqc#5528) which does it using two draw calls on the FBO. If you need to do it in one draw call for performance reasons, we'll have to open a feature request to allow positioning of input frames. The long story is: - Input frames are positioned relative to their position on the destination channel - The FBO has to be your destination, since the dest channel frustum is always the one used for rendering - The 'right' image will be positioned at the same place, i.e, moved, on the right Quadro window. The monitor equalizer does the inverse (positioning and scaling multiple segments on a single channel). Maybe I've overlooked some hack to do it nevertheless. Implementing the feature should be doable in a couple of days, let me know how important this is.
