Back story: I’ve upgraded my main system with a new graphics card, CPU, and SSDs. I had leftover parts so I decided to make a small form factor, portable gaming PC with my leftover parts. I know that you can carry display signal over USB-C, as well as power. So I wanted to buy a graphics card that was both on the cheaper side, and that had a USB-C port as well. I just bought an RTX 2060 Super founders edition on eBay. Most of the 2060 Super versions do not have a USB-C port. I wanted a little bit more insight from all the folks on this subject. It aside from the ones that I asked in person, and potentially from anyone who may have already tried this.
Can you power a portable monitor using just the USB-C port on the graphics card?
Thank you in advance!

Apparently, it can deliver up to 27w, so as long as the portable monitor in question uses less than 27w, yes.
I seriously think the USB-C port on GPUs were ahead of their time. Would be useful now that the cable is really taking off.
Ive used it multiple times to charge my macbook pro, so yes it can be used for power.
I’ve tried this port on the Lenovo M15 and L15 USB type c portable monitors and it didn’t work…still need some sorta adapter…
Yup, works and is intended. Had a smaller 15″ portable monitor as second display hooked up to my 2080 Ti for years before the 2080 died recently. Also ran a oculus quest in link cable mode off of it (data streaming and charging).
Too bad they don’t have usb-c ports on GPUs any more – apparently because the [virtuallink standard died ](https://www.tweaktown.com/news/74978/geforce-rtx-30-doesnt-include-usb-port-because-virtuallink-is-dead/index.html). Was really disappointed when shopping for a rtx 40xx series GPU recently and none included an USB port. That’s when I stumbled upon the explanation.
Edit: you probably knew that but the USB C port on the GPU also provides data connection to the host, not just power and video signal. Meaning some displays have USB Hubs/KVM switches and have it run off the same cable. (Doesn’t work if you use an USB to DP adapter in between or something like that). connect peripherals to your display and voila. Only seen that on ordinary large displays tho, so not the “single USB C cable also powers the display” scenario.
Edit2: apparently some of the newer AMD cards now come with USB C ports. Don’t know if it has the same capabilities as above.
I bought a 2070 specifically for that USB C Port and put my 1080 ti to a 2nd rig.
My 2070 connects to an Xreal Air display glass. It works for that.
It also works on a Type C monitor / type c hub with HDMI.
Not always but some allow your vr headset or monitor to be charged at a relatively low speed
2 days ago I just found out my videocard type-c can work as a usual USB, lol
Yes
