HDMI out is a thing that most people can't realistically use to connect their PC to their TV because they're in different places.

I bought a pretty cheap HDMI extension cable that snakes from one end of my living room (work desk) to the other (tv+consoles) that would argue otherwise!

A laptop will work fine. Even a Android / Win10 tablet with HDMI out will emulate N64/PS1 decently.
