Yet another post in my series of ‘if I don’t document it, I will forget how to do this again in 2 years time!
To access the Hospitality Mode of Samsung TVs, press the following buttons in order: Mute 1 1 9 Enter
This mode lets you set fun options like automatically turning on the TV when it receives power (like they do in hotel rooms!) which works nicely with a smart plug. You can also set volume limits (probably handy if you have kids), and the default input source.
Once you’ve finished messing around, turn your TV off and on again to exit the hospitality mode menu.
This was tested on an ancient Samsung 40H5000 TV, and may not work or require different steps on TVS that aren’t nearly a decade old!
