- No, it didn't...
My bad. A couple years ago I had considered adding one as a second display but wanted to know if it would work on my PC. I found a handful of forum posts that said it did and that people had gotten it working over miniDP. Just without the ports. But I did a little searching now (I ended up not buying it) and apparently that's not the case. Whoops!
I guess I could see how it might work with a PC with the right hardware... and I hope it does become a standard. I guess I was thinking more about other HDMI devices like PS4, Xbox, DVR, etc. I suppose some kind of adapter? But, could such devices be daisy-chained so that it doesn't require switch boxes or messing with cables? It just seems odd it doesn't have a couple of more ports.
I have no idea whether it'll work at all. But thunderbolt can work in two directions (For example, you can actually get an adapter and plug a Thunderbolt 3 device into a Thunderbolt 1 or 2 port; of course, at reduced speeds and capability. It can be reversed.) and DisplayPort can be carried over a thunderbolt/USB-C connection. So it's technically feasible, I think, that an HDMI to USB-C dongle could be connected to the back of the display and then an HDMI system connected to it. Or DisplayPort.
But I have no idea whether the LG display could support that. I just think that's technically possible with the USB-C / Thunderbolt 3 standard.
If I had to guess? I'd say, probably not.
It is a standard. It's not on game consoles or TV's like HDMI, but USB-C and Thunderbolt 3 is an existing standard. And it's already on a handful of devices. I can't see any reason you couldn't plug, say, a Dell XPS 15 into it. This is not a proprietary Apple connection.
