As a woman who is bothered by the “females” thing, “female humans” doesn’t sound bad to me. It’s because “female” is used as an adjective here. It’s the same reason “black women” sounds fine, but “blacks” sounds bad. It’s reducing someone to their gender only, as if they’re not humans, too. It feels otherimg.
I have an LG TV too, and I use a Steam Link for this. I think they’re hard to find now though. I’m not sure if there is another way, but I haven’t found one if there is.
