I run my wires without the wall plate. But then I have so many wires coming out of the wall and often out of the ceiling to the projector that I do not have a choice. If I run a DVI cable I do not know of a wall plate for this. While there are DVI to RGB adapters I do not know if it is worth the effort.
I would not use the wall plate but perhaps I need to be more anal. That said I would run my RGB cables out of the wall into the switcher and out of the ceiling into the projector. The issue is aesthetics and time not signal quality or degradation.
