There are a number of options for watching TeamTV on TV.
They can be divided into wired and wireless solutions.

Wired solution:

The easiest way is to connect your laptop to your TV via an HDMI cable.
You then use your TV as a second monitor, which often works well.

Wireless solution:

Whether you're working with Windows or Apple still makes a difference. 

Windows: 
You may have a tablet running Android or Windows, and then a “Chrome cast” is a good solution for working wirelessly. You can find plenty of information about this on the internet.

Apple: 
If you have an iPad or a laptop with mac osx, you can work well wirelessly via Apple TV.
