# for this code to work, newer consumer displays require an encryption key for the commands

# for newer than 2018 models that require keycodes, look up Wes Souza in github, there is a working
# json library for the AES-128 encryption required for newer than 2018 model LG TVs
# with npm installed, sudo npm i lgtv-ip-control-cli for the npm library with Command Line Interface
