Hi Susan,
Please make sure that the HDMI CEC settings of the screen itself is active and a general shut down of the the screen after a certain time of "stand by" is deactivated.
Some screens also have extended HDMI CEC settings where you can separately can edit the option for external devices to switch your screen on and off.
Please check the manual of the screen in use for this settings.
Greetings from Düsseldorf
