We have 3x TCL 49" Android TVs wall mounted in our office which are all linked to a splitter/amplifier which goes back to a single headless Windows PC. We sometimes use these to watch sports while we work or cast videos to for staff/customers to watch etc. Most of the time they sit there off doing nothing. Recently it occurred to me it'd be good to use the TVs as large digital photo frames, whereby the TV's would automatically power up and start playing a photo screensaver from the headless PC, from a folder of images I've selected. This seems like it would be pretty simple to do in Windows, what I'm less sure about is how to get the Android TVs to automatically wake up and turn off at certain times on certain days. Ideally what I'd like is if say the 3 TVs all turned themselves on around 8.30am, picked up the source of the headless PC which is set to start it's photo screensaver after say 5 minutes, then the TVs shut themselves down about 5.30pm each Monday to Friday (not on weekends, nobody is in the office).

​

Is this possible? Either through Android TV natively, or using a 3rd party app?
