The concept of "screen" in X11 is different from what you are thinking
about.  One window cannot span multiple "screen"s.  I guess you are
thinking about a "framebuffer" in Xinerama extension.

No.  Because there is no Xinerama support in the X11 version, Emacs
doesn't have a concept to distinguish multiple framebuffers yet.
