I found something about some recent-ish LG TVs having a default mode that shows static, but I couldn’t find a clear answer on why, and the way to disable it is to enable “Cable DTV”, which seems to suggest that it might actually be trying to get analogue signal by default…?

That noise is horrible; why would someone simulate it rather than just show a blue screen?

No Claude? It’s pretty good in my experience, and I follow someone on twitter who does absolutely wild things with it.
