Plug the HDMI cable into the TV and your laptop,
Turn on your laptop
Wait until windows has loaded up,
Press the key combination to toggle output (different depending on laptop, for Samsung its F4, for ASUS its FN+F8/F8)
Should toggle between main display, mirrored, extended
Once either mode is enabled, right click, display, make this display main display
