What is upstream?

According to a comment[1]" "An upstream port connects to the host device (PC) while the downstream ports are where you plug in peripheral devices (thumb drives, printers, etc.)."

Of course the 5k monitor does have three USB3 ports. (Not Thunderbolt ports, ostensibly because there isn't enough bandwidth left.)

I like how they use USB-C inputs for USB3 ports as well. Not at all false advertising and confusing for end-user.

Why? This is the promise of USB-C "Every port uses the same connector, so you only need one type of cable". Of course, with the different cables supporting different ports it is not ideal.

It's when you connect your keyboard and mouse to monitor instead of laptop/pc.

Essentially only one wire goes to your laptop/pc instead of 3.

I'm pretty sure this monitor lets you plug in keyboards and mice to have them work with the host computer.

Nope, it does not.

Really? Apple says, "And three downstream USB-C ports (5 Gbps) offer additional connectivity and power to compatible devices and accessories." What makes mice and keyboards incompatible?

Edit: according to this random internet stranger, it works fine: http://www.apple.com/shop/question/answers/product/HKN62LL/A...

I don't know where you got that impression. I have this LG 5K display and I'm typing on a keyboard connected to it right now...

Untrue. I have one and works just fine with my mouse, keyboard, sdcard reader, external hard drives, etc.
