Does the LG TV send its current state to the PC?

[iyadoff]

Thank you very much for this application... My question is how can I run LGTVcli.exe or how can I know the status of the LG screen whether it is off or on... that is, can the LG screen send me its current status... because I want to calculate the period of time that the LG screen was turned on. Thank you very much.
