Hi Sober,
Try running your computer in Clamshell Mode. Go to
https://support.apple.com/en-ca/HT201834 to learn how, or just google Macbook Clamshell mode.
Or another thing you can do is press Command-F2 to extend your desktop to the TV, then slide your application / browser / whatever over to that TV.
