(Note)
The monitor will disconnect the connection if no packet data is received for 15 minutes.
And the controller (PC) has to
3.3 Communication timing
The controller should wait for a packet interval before next command is sent. The packet interval needs to be longer than 600msec for the LCD monitor.
