Nowadays, the most of laptops have HDMI which is a type of connector most of TV have. But that is not very fun to have cables laying on the floor. I prefer to do it wireless. You can use apple tv or android tv box. They can use do screen mirroring wireless. But they are normally priced over $99. I like to ChromeCast which is only $49. Then I can project my android phone and my computer with chrome browser. Please don't misunderstand that is only casting my browser screen, I can cast my whole computer screen to tv! That is easy and just $49.
