Yes it comes up on Monitor 1, that is why i thought it might not be set in display properties to be "Primary Monitor" you can try and disable monitor 2 in display settings, restart, start RB, then enable monitor 2 again. Or try and swap the monitor leads on the video card if both are the same type
connector then setup again in display settings.
I think you should be able to sort that out, i have used 2 or more monitors on a lot of pc's
and there is usually a way around it.
