For the past 10 years or so I’ve had a PC hooked up to a dumb TV to stream my TV. Now I’m officially old and have kids in elementary school. The PC is finally unbearably slow but now I have no idea what to replace it with, or frankly even what my options are. Smart TV? Casting Stick? new PC? some newfangled option i don’t even know what to google?
I do the same as you, use a PC with a TV as the giant monitor basically. I would just get a new PC personally. So much more you can do with it.
