I recently purchased a new Samsung Smart M7 monitor. It comes with a remote control that has a power button. There's also a button underneath the monitor that can be held down to turn it on. However, I'm unable to power the monitor on or off using the remote control; it only allows me to control the features. I managed to turn it off using the button, but only when the monitor goes into a mode indicating that it will be turned off in one minute in stable mode. However, it's unclear how to access this mode in the first place, so I have to unplug the monitor from the socket every time. This is quite inconvenient, especially when I'm watching YouTube on the monitor, and I can't turn it off using the remote.
