Multiple monitors or one large 4K TV?

I have an idea and want to know your thoughts on this or if anyone else is doing this.
I was thinking of getting a large 4K TV as a monitor and have four different windows open and spread out on the screen. My thoughts on this were that it would be easier to move around form window to window on one large screen instead of looking on moving between multiple monitors.

I have created a screen shot to show what I was referring to.

What would be the pros and cons to doing this?
