Yi home mac desktop

I have 3 Yi home cameras, using mac desktop for monitoring. The desktop proivdes up to 9 cameras, but I have 3 only, hence the display showing all 3 cameras ver small. I have searched every where if is possible to enlarge the displays as a group of 3 cameras. I know I can indivisualy enlarge the each camera display, but I want to onitor them the same time.
Any solutions?
