Project idea: chromecast, but for VGA. VGA can output 5v, so you won’t need that awful USB dongle to power it up. You plug it in the VGA port, and it just works.

Nothing has a vga port anymore

@Lensflare best

Can't you just airplay to your tv?

I dont know the name of the linux package but i managed to set it up very quickly and easily.

For windows, don't know, don't care...

I mean I do it all the time since i have tv for watching movies and series on pirated websites and occasionally for videogames

I am probably missing some cool features that Chromecast has, but it seems that it doesn't fit my use case
