So, I fixed all my computer problems with how I'm gonna run it (TV won't work and neither does streaming on the old mac) I came to a conclusion by streaming using ethernet on a school laptop. But heres the problem. My brother is hosting the stream and at the time of this post, he's at work. He forgot to unlock the pc. "Just unlock it" you might say, but heres a problem with that: I can't. The monitor has been completely off and HDMI is on and plugged in fully, the computer is running and I believe the monitor is plugged in right now. Once i fix the monitor problem, the other one is too, so if anyone can help meh, I'd appreciate it a lot.
I understood exactly nothing in this whole sentence, what'd you mean exactly? Someone please explain too me what he's meaning/saying, as I understands exactly nothing.
Make sure to check all of the TV's cable's. Check the plugs for the TV, also make sure to check if you haven't missed any cables for the TV, because this is why it's turned off. If all of the Cable's are in the right place, and the TV isn't working, I would suggest talking to a PC Repairer, in that case, you should be good to go.
It sounded a lot simpler when I was writing it. Anyway it fixed after a bit. I'm probably going to delete this post soon.
