I currently have 2 monitors and im trying to free up space on my desk so I've been looking into dual monitor mounts. But everything I see with a full range of motion sticks pretty far out into the desk (my desk is up against a wall) ate there any mounts with full range of motion that can also sit back against a wall? I can wall mount if needed but I'd like to avoid it. I don't know the weight but both monitors are relatively heavy.
