What is the best way to display an image on a TV on Orange Pi from server Linux?

Question

linux

So, let me explain the question.
I'm going to buy Orange Pi PC H3 to run Node.JS on it - my smart home script.
I would really like to have something like a beautifully designed information panel so that when the TV is not in use, you can see the status of the smart home system and information from sensors on it.
The TV is old and only supports RCA input.
And so, what should I do: buy an HDMI->RCA converter and connect a TV via HDMI to Orange PI, or synthesize an RCA signal using GPIO outputs?
Which of the options can you advise me, and how is it possible to implement this using server Linux (which, by the way, is an optional condition, the main thing for me is that the Node.JS script works and is enabled by autorun and there is control over SSH)?
All this must be implemented taking into account the 1GB RAM limit, since I don’t want to buy a more expensive model.

Answer 1

Put some lightweight graphical environment on Linux and a browser in it. Server, not server - it's all conventions.

Answer 2

you can do without DE and prescribe Xs to directly launch a browser with a site.
read kiosk-mode and ./xinitrc exec
i.e. write
exec chrome --kisok %what do you want to run%
in ./xinitrc

Answer 3

Google "Chrome in kiosk mode".
There and about the lightweight environment and about the browser will be.
