Cable is the cause
When the model supports DPM, if the function does not operate, then generally, you are probably using a non authentic cable which is not provided from LG Electronics.
For instance, if specific pins of the HDMI cable fail to detect DPM operation, the function is not implemented and so on.
You are recommended to make a connection with the cable provided from LG Electronics.
In case of monitor with a built-in TV tuner, edit the name of connected device.
On the input terminal connected to the PC, set [HDMI1 or HDMI2] : [Edit Name of Connected Device] to PC.
If you connect the monitor and the PC with HDMI, the screen size or the image quality is not suitable for the PC environment.
When you connect the HDMI cable for the first time, if it says [Is the current input device connected to the PC?] then use a remote controller or the menu button to select [Yes] and check it accordingly.
