Quite familiar with nano. For anyone else curious about editing config.txt
Raspberry Pi Config.txt [LibreELEC.wiki]
Now regarding the HDMI enable thing. Since I guess this is a teaching how to fish or you forgot to answer. Took a quick min to find.
Anyway. Turns out the HDMI enable thing in config.txt for the rPi 4 was this: hdmi_enable_4k=1
But best I found. That's only for I think, what, live TV because of the higher frame rates or something ?
Bec. I did notice that I was able to play 4k the other day. Not live though.
*** Dont have that kind of setup but would love to feed a roof antenna if I can for local stations if someone can help with that, let alone tell me if that's even possible on an rPi. ***
Also, regarding the HDMI thing, I haven't tried it bec I don't have a spare cable let alone a micro adapter.
Does the 2nd port work OOB on the rPi 4 with the first one also in use ?
Possible enagame to eliminate a second rPi 4 I'd rather not buy, is to just get a long enough HDMI to attach to the 2nd port on the rPi 4 and run it to the living room TV from the rPi 4 in my bedroom.
Ty.
