DisplayLink transports video over the USB bus, rather than using one of the alt modes of USB-C. As you can imagine, this introduces compression artefacts and substantial CPU overhead. It's passable for web browsing. Watching any sort of video is painful and forget about any sort of gaming or latency sensitive application

Ah, this is why the displayport to 1080 screen connection looked so bad. I have a mediagear usb-c hub and also a cable matters thunderbolt to dual displayport adapter. Video is much better over the latter, for sure.

DisplayPort is fine.

DisplayLink is not.

The confusion is deliberate, the company renamed itself to DisplayLink a few months after the standard came out.
