Thank you very much for your fast reply
I’d like to comment on a related topic: is it possible to just stream from one portion of the source desktop? Eg. in my setup, most of the time I just want to have remote access to the specific region corresponding to one of the FullHD screens. This would mean a practical surface of 1920×1080, which imposes much lower encoding and performance requirements on the server side.
I know the options related to the resolution and the screen selection on the client side, but I haven’t been able to find any document which states that any of those will instruct the server to actually encode only a specific sub-region of the whole remote desktop.
