If the resolution is the same as the monitor, then the pros is that the TV is generally larger in screen size. Resolution may also be a pros.
Cons - unless you are making the TV as your primary monitor, it can be a pain to hook it up to the TV every time you want to play a game. You may have to move your keyboard and mouse unless you use a controller.
But there's not much pros/cons over a monitor. It's definitely easier to set up multi-display gaming on monitors over TVs.
