I am New to CCTV and DVR systems please help. 
I have recently upgraded a customers setup from Video recorder to PC based DVR with a 128MB graphics card and TV out. 
All i did was to remove the hardware(Robot MV16i multivision plus processor, the Video machine. and the two B/W monitors) 
He has 10 cameras and all is working fine. 
  
The problem now is that he wants the two additional monitors added to the system at minimal cost. 
What will i need to split the signal, to the pc and 2 monochrome monitors.
