Swann 8 Channel DVR-8 Cameras Split between 2 Monitors Help?

[MPC 0]

As the title suggests I currently have 4 cameras hooked up to my dvr displaying on 1 screen.

 

I would like to add another 4 cameras to my current dvr, but display them on a second screen.

 

Is this possible with the current system I have and if so how would I go about achieving this

 

any help would be much appreciated.

 

all the best
