What a strange spec sheet. They specify that it has Ethernet, and mention multiple times that it's an RJ45 port -- but at no point to they tell you what variety of Ethernet (100Mb? 1Gb? 10Gb?) it is, let alone what chipset. It also has a display-port output... for what? Similarly, it has three USB-C ports: One upstream, one downstream, and one unspecified. Huh? I suspect there's some chance that this is a decent device, but the marketing copy needs an editor.
Also, why does it come with a USB-A to USB-B cable if it doesn't have a USB-B port? I'm not sure if it's more likely that they don't know what ports are on the monitor, or what's in the box...
