I just wish I could get the auto-turn off timer to disable. I've disabled it everywhere in menus. Still, after a few hours of it being connected to my Apple TV 4K, it gives me the whole "TV will be turned off in five minutes unless you press a button on the controller" bullshit.

Other than that I just want the thing to be a lowest-possible-latency, accuratest-possible-colour dumb display. No cool shit, just a dumb accurate fast panel.

If you can get your hands on a service remote it will allow you to access a menu to disable that and a bunch more (a lot of the OLED burnin prevention features you can’t normally fully disable)

If you have a phone with a IR blaster (mostly older LG phones) you have download an android app that with act as an LG service remote

You can do it with a rpi, ir diode and resistor even. The tool for sending and receiving ir commands is called lirc

Huawei and Xiaomi phones have IR blasters as well. I always try to buy phones that have those, because A) "i lost the remote" and B) "shut off every TV at the store" is hilarious.

The first device i had that had this was a Palm, and it wasn't like "here's a remote control" it was "this 1 button will cycle every known TV IR code for the power button." Someone eventually released an actual IR blaster app for Palms, though.

Some old Samsungs have it as well, such as the Galaxy S5.

This sorta thing? https://www.ebay.co.uk/itm/390856037063 or https://www.ebay.co.uk/itm/363604565328 I don't have an IR blastable phone.

Maybe you could periodically give some remote control command through one of the WebOSTV python libraries. Needs networking though. Alternatively, an Arduino/ESP that sends a useless IR signal.
