I'm still not sure what you are trying to accomplish
In this particular case, Kadete has made transformations and warped his content in the advanced output. He want to see the result of this in the composition output monitor in the main GUI.
In general, Kadete is still getting his bearings on how Resolume is designed to work. He defaults to blaming the software for lack of features when something doesn't work as he expects.
For instance, in this case, he probably has used lots of layer to slice routing to position and warp his content, with the obvious drawbacks that has for the general workflow. As explained in the manual and in several posts on this forum, a better workflow is to use the layer and clip properties and effects to roughly position your content similar to how it looks on stage. You then use the Input Selection and Output Transformation tabs to do the final aligment warpings required for matching the image to the objects you're projecting on.
