Connecting a pen display to a USB-C port on a GPU

Overview

It might be possible to use the USB-C port on your GPU. It depends on what you are trying to accomplish.

Connecting for power, data, and video

In this case, the cable must carry video, power, and data. Currently, I only know of one GPU series with a USB-C port that might work for this case: the NVIDIA RTX 2080 series.

To be clear, I have never personally tested this scenario with an RTX 2080 card.

Keep in mind that USB-C ports on a GPU almost never supply power. They will send a video signal, and they might carry data, but without power they can't support a one-cable connection on their own. So don't assume a GPU's USB-C port will work for a single-cable setup — a few people have told me they made it work, but I've never seen it myself.

Connecting for video only

If a USB-C port is on a GPU, it should support a video signal.
