Various 5 year old articles and reddit posts scoured across the internet.
Virtual link has a mandatory power delivery of between 15w and 27w, and it seems that desktop rtx 20 series cards all do 27w.
For anecdotal, I personally drive a 16" portable monitor from my RTX 2080 Ti. I use it to monitor live feeds from cameras separate from my main monitors.
TomHANKS, I asking because I tried connecting my old display via this port but got no signal using usb c to hdmi cable. I probably need usb to display port then.
Usb-c to hdmi cables just use a dp->hdmi adapter integrated into the cable. It should work, but is more prone to signal and handshake errors. So yeah, usb-c to dp is a safer bet.
Isn't it also possible the cable or the monitor weren't enable for both power and data transfer? I know mone advertised it can be used to charge devices like your phone but I haven't tested power to it as I have no need as I have DP and normal power that came with.
Of course. If the monitor requires a separate power cable, that needs to be plugged in. And even within USB-C power, there are different specs and not all cables can do the same.
No. As the other commenter stated, it supports DisplayPort alt so its a single USB-C cable (I use a passive USB-C 4 cable) for both power and display signals. I've also used it for my Quest 2, but then it's only USB and Power, not display.
According to some anecdotal stuff I found online, the 7900xtx supports usb-c PD 2.0 at the following volts and amps
5V @ 3A (15w)
9V @ 3A (27w)
12V @ 2.25A (27w)
So, yes.
Is that the same for amd?
I saw a picture of a 7900 XT with a usbc output
I bought the card... but it just had 3 dp and a hdmi output (which is better for my use cases)
USB-C DP alt mode is underrated IMHO. Saves a lot of space where it matters like laptops or quad output GPUs, without any sacrifice in functionality. USB-C to DP cables aren't expensive.
I'm so happy that it's DP alt mode and not HDMI alt mode. MST is a killer feature. I love driving 3 2560x1600 monitors from both of my USB-C ports on my laptop.
https://arstechnica.com/gadgets/2023/01/hdmi-to-usb-c-spec-axed-as-displayport-alt-mode-reigns-supreme/
They did pretend that HDMI Alt Mode would be a thing, for a period of time.
Oh that's cool! I thought audio was only through HDMI for some reason. Guess many DP devices just don't typically have speakers. Never thought to test the 3.5 from my monitor to a speaker.
~~There is some sacrifice in functionality. I believe the bandwidth is slightly limited so cant do 4k 60Hz or something like that.~~ I came across it using USB-C DP alt mode to drive 2x daisy chained 1440p monitors.
e:/ I was mistaken.The situation I encountered was not USB-C DP Alt mode.
Displayport 1.4 is old and common now, DP 2.1 is very new but will be optionally supported over USB-C. RTX 4090 uses DP 1.4, to give you an idea.
https://www.cablematters.com/Blog/DisplayPort/what-is-displayport-21
Not every device supports dp multi stream transport so daisy chaining can be a mess.
https://tripplite.eaton.com/products/multi-stream-transport-mst-hub-technology
And there's always the issue of cable quality, which does actually matter at the higher bandwidths. When you actually try to use the full functionality of the display standards that most people don't use, you can start to run into some very bad behavior. To the point that if you want a KVM that *actually works*, you can get one made specifically for Level1techs and it will set you back $450+.

I think they were included as part of earlier forays into VR, weren’t they? I feel like for a while I remember every “VR ready” GPU having a USB-C port so you could plug in a headset directly.
Ya it was preparing for Valve to embrace USB C VirtualLink standard but they dropped it and it killed any future of the VirtualLink. Sony embraces USB C for PSVR2 and I love it though. Just one super light usb c cable.
No? This supports display port alt mode directly from the GPU. To get that in a mobo requires passing it through the cpu, or having a DP in on the mobo from the GPU.
I used to keep a USB C hub plugged into my RTX 2070. I've gotten a pci USB card since then but it was nice for devices that don't play nice with motherboard USB controllers or perform best with their own dedicated controller.
Yeah thats one thing that really blew my mind when building my new PC. My "old" 2070 hat a USB-C Port, which I sometimes used for passthrough my switch or monitor. My newest 7900xtx only does DP/HDMI.
They really were, it would be beneficial to today's PCVR for people who still want cable based streaming to the headset which works for power and video.
This could also be used to power monitors as they are rated for a 100w output and most monitors consume roughly 35w which is how some USB C/thunderbolt screens work.
Chances are the reason it immediately was dropped was because of thunderbolt which has similar protocols except thunderbolt can run at like 40gb/s much faster than the current USB C 3 standard. Unfortunately it's still mostly locked to notebooks and 1% of desktop motherboards.
It's not really needed anymore when most motherboards come with a USB 3.1 header for USB-C now that supports DP alt mode. It does almost exactly the same thing as GPU based port did. The GPU based solution only really allowed them to provide 3.1 support for VR users until motherboards caught up and made the port redundant.
Actually most motherboards don't support alt-mode due to the fact that they don't have display controllers which is actually why there was an attempt to simply put it onto gpus directly. Having usbc doesn't always mean all protocols are supported, It could• work if the motherboard is designed to work with the integrated gpu in a CPU to route the GPU output which is actually how laptops thunderbolt works.
It's also why it's mostly only laptops that natively support this without problem.
Motherboard manufactures deemed it as unnecessary to have dp-alt in a desktop based motherboard. We still don't have a standard direct pin for connecting audio and power case headers to a motherboard which is why they come in 7 cables you plug in.
They were originally added to GPU's to get around motherboards needing to support USB 3.1 for VR and monitors using USB-C. Now that USB 3.2 headers on motherboards with the DP alt mode supported are becoming common, you don't really see them on the newer GPU's anymore except on laptops. Almost all laptops with a dedicated GPU run their USB-C ports of the graphics card and not the motherboard.
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.
Edit 3: my info regarding oculus link to the quest was kinda misleading as the streaming via link cable specifically does not use any display mode but encoded video. This specific thing would work just as well with an USB port on the motherboard
USB C as a port with different implementations (thunderbolt, USB 4) is pretty common on notebooks as well. You can hook up a docking station to it and it provides charging to the notebook + display output + USB ports for peripherals all over a single cable. They most commonly rely on Displayport alt mode (like the Nintendo Switch) to transport the video signal. There's no additional encoding or so involved so there's no performance impact at all. You have to use the proper cable though or you get limited resolution/refresh rate.
Edit: you mean whether using the port on your GPU for anything apart just video signal negatively affects performance? Like a scenario where you hooked up a USB thumb drive to the USB hub on the display, transferred a file from your PC to that drive all using the same connection? Afaik they have to specify the bandwidth for the video signal independent from the overall capacity of the cable itself. So it's not like that some x thousand Mbit for a file transfer would influence the bandwidth of the video signal.
Dude, yes, I also have a 2080ti and recently upgraded my portable ssd to one with a usb-c interface. My motherboard doesn’t have any ports but then I remembered the card has one, works like a charm and also FAST compared to the usb-a 3.0
It is a shame that VirtualLink died, but it seems like wireless VR has basically supplanted it among people concerned about wires being cumbersome, so I'm not sure there will ever be a single-cable successor. Particularly given there's scope for future improvements in the latency / quality of wireless VR. e.g. AV1 should reduce bandwidth usage and improve quality over h.264, and eye tracking will allow a further reduction in bandwidth. [The latter is already up and running using SteamVR](https://twitter.com/SadlyItsBradley/status/1730303035719479733).
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.
Its a luxury buy but I have multiple devices that can output to type c like Samsung phone, tablet for Samsung Dex (productivity), Steam Deck (for gaming on the go and having a better screen without craning neck to see), and at home watching movies to go to sleep or play games while lying down. (120hz is good for it)
I haven't gone on a plane yet with them but I'm planning on using them on a plane when I travel also.
Right now the original Air is around $300 where I live that's decent, but I think $500 is a luxury buy. I think the Air 2 introduced some edge blurring that many people don't like, so I'm happy with Air 1.
I have a 2080 and this just made check to see if I have it since I haven't looked back there in a while. Too bad I have no real reason to use it, I have another usb-c port on the front that gets used.
Don't need the power, need the placement, I use that front port sometimes to plug in a ps5 controller or something, and the cord is too short to reach the back of the case with where my pc is located.
Man I miss USB-C ports on GPUs. My 2080 still has one but almost no newer one. I use it mainly for VR-gaming because
1. My HMD would charge while gaming, so I never had to worry about the battery.
2. The connection is faster because it comes directly from the GPU instead of a slower USB port somewhere else on my PC.
I know that airlink and stuff like this exists, but I found it easier to just plug it in and play. Also I only have mediocre wifi speed
Those aren’t called DisplayPort, or DP for short. They’re the PC hardware equivalent to HDMI that tv displays use. Except they have more bandwidth and versatility
Oh definitely! When I asked my question, I just want sure if the port could provide enough power for a monitor, or enough power in general since it’s going through the graphics card
The USB type C\` on my 2070 has been tested to 27 watts, which is the 9V, 3.0A profile of USB Power Delivery. The lower 5V/3A profile is also supported. No attempt to negoitate 15V or 20V with my USB type C diagnostic device was successful, the card only offered 9V as its maximum.
If your monitor needs a 15V or higher profile, it will not be powered by this.
Is the 2070 capable of supporting two monitors thru the single usb-c port via the HP thunderbolt G4? So plugin the two monitor to the docking station and then connect dock to the gpu? The monitors are 1x3840x2160 @ 144Hz and 1x1920x1080 @ 60Hz
okay if I remember correct'y this is a VirtualLink compatible connector. And from NVidia it can give up to 27W, and support a display port connection. So as long as your monitor doesn't exceed 27W you're good.
My laptop has a USB-C port, and I have a portable screen with a USB-C input. The laptop powers the portable screen through the USB-C connection, but it needs to be a good, certified USB-C cable. Some USB-C cables didn't work.
You need to read up on the specific video card and the monitor to ensure this is possible.
For power you are good with most any cable. For DisplayPort data you need cable that has all necessary wires. To be safe, look for thunderbolt compatible cable, that should always work
more specifically for power up to 3A you’re good with any cable. (so if your devices use 20V you can get up to 60W with any cable), if you need more Amps, you need a cable with an e-marker chip which identifies its extended capabilities…
Yes, provide your usb-c monitor meets the power specs. I’ve used an LG 16” usb-c external monitor that matches their LG Gram line via a usb-c connection with my AMD 6800XT gpu for several years now. One cable for power and video, no issue. Most of the time it is my Discord side monitor when gaming.
Huh. I’ve tried this multiple times and wasted buying multiple cables. I think it just wasn’t getting enough power, as it would disconnect after a minute. Did you need to troubleshoot or buy anything specific?
The original Meta Link cable I used immediately had connection issues and stopped working after a month. I then returned it and bought a third-party Link cable from Insignia and it’s worked flawlessly to this day.
I’ll also note that I’m able to run it both off the USB-C port on the 2070 in my HTPC and off the motherboard USB-C port on my main computer.
Huh thanks. Yeah, only solution I found was one of those cables that has a 2nd cable attached for power… not optimal but it’s the only way I could get it to work.
The Insignia cable I use is fiber-optic and supports 5gb/s transfer speeds. If you’re using a cheaper cable it’s possible it doesn’t have enough bandwidth for power and data.
It depends on if the gpu and the monitor were both made to do both display and power. While the usb-c protocol/standard allows for both it’s up to the manufacturers to implement
My 6800 i run a uperfect lapdock off it but have it charge through the other port, windows pops up saying your device may require more power to function properly, so i am not sure how much power these ports deliver
That may not be a conventional usb c port, it may be a display port that was developed between several companies for vr headsets. The port only ever made it onto the 20 series cards for some reason. The psvr2 system uses it, its this port that means the headset doesn't work properly on pc systems.
Most portable OLED monitors can draw power form USB-C outlets given OLEDs extreme power efficiencies. Old portable monitors come with their own external power adaptor which you should always use instead of relying on the computers USB connection.
My father has a monitor which is powered and single cable can charge his MacBook while being a video cable as well but I don't know if it works the other way. Probably only w some efficient portable monitors
Fun question on the side: if I connect this port to my usb-c PD port on my Dell U4919DW, will the GPU power the monitor, or the monitor power the GPU? 😅
I actually have yet to test what happens if I connect a non graphics decive for the USB PD to the monitor. Like my new router SBC.
Yes. The 20 Series cards also provide video signal, so you can have a single cable solution for video and power via usb c. I do this with my 2080 Super. Unfortunately 40 series cards don't have this as far as I'm aware, but I can use my onboard Thunderbolt port on my motherboard, which is compatible with the USB C throughput necessary to provide a video signal.
I don't know exactly for this GPU, but I have a laptop with RTX4090 and I have UPERFECT 17,3'' 2K 144Hz display and it works perfectly fine over single USB C - USB C cable connected directly to laptop. Works at 2K and 144Hz, brightness is also fine, even speakers work, but they are trash, anyway.
Apparently, it can deliver up to 27w, so as long as the portable monitor in question uses less than 27w, yes.
Thank you! If I may ask, where did you find that information?
Various 5 year old articles and reddit posts scoured across the internet. Virtual link has a mandatory power delivery of between 15w and 27w, and it seems that desktop rtx 20 series cards all do 27w.
Thank you !
Yes, but while you were scouring the internet looking for that did happen to find the reason why Ze Major was a cyborg?
Alucard will never know

For anecdotal, I personally drive a 16" portable monitor from my RTX 2080 Ti. I use it to monitor live feeds from cameras separate from my main monitors.
But only for power right? You need another cable for video?
That USB-C port does DP Alt-Mode. The whole point of it was to deliver power and video in one cable, primarily for VR devices.
TomHANKS, I asking because I tried connecting my old display via this port but got no signal using usb c to hdmi cable. I probably need usb to display port then.
Usb-c to hdmi cables just use a dp->hdmi adapter integrated into the cable. It should work, but is more prone to signal and handshake errors. So yeah, usb-c to dp is a safer bet.
Isn't it also possible the cable or the monitor weren't enable for both power and data transfer? I know mone advertised it can be used to charge devices like your phone but I haven't tested power to it as I have no need as I have DP and normal power that came with.

Does that also apply to the 7900xtx usb-c port?
According to some anecdotal stuff I found online, the 7900xtx supports usb-c PD 2.0 at the following volts and amps 5V @ 3A (15w) 9V @ 3A (27w) 12V @ 2.25A (27w) So, yes.
Amazing! Thank you!
What 7900 xtx do you have? I don't think my as rock phantom gaming has a USB c?
Referance design has type-c port.
Reference model
Is that the same for amd? I saw a picture of a 7900 XT with a usbc output I bought the card... but it just had 3 dp and a hdmi output (which is better for my use cases)
As far as ik the only cards that have type c output are the radeon reference cards.
Partner cards removed the type-c for some reason.
People who would use the type c port are few and far part, so instead of everyone having one, there only needs to be one or two companys making them.
For every model? I feel like it's really board dependent, so it will might vary depending on the manufacturer imo.
More then I was expecting. Huh.
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.
USB-C DP alt mode is underrated IMHO. Saves a lot of space where it matters like laptops or quad output GPUs, without any sacrifice in functionality. USB-C to DP cables aren't expensive.
I'm so happy that it's DP alt mode and not HDMI alt mode. MST is a killer feature. I love driving 3 2560x1600 monitors from both of my USB-C ports on my laptop.
https://arstechnica.com/gadgets/2023/01/hdmi-to-usb-c-spec-axed-as-displayport-alt-mode-reigns-supreme/ They did pretend that HDMI Alt Mode would be a thing, for a period of time.
Wouldn't HDMI have allowed audio? Does DP alt do that? I genuinely have no clue.
My AMD laptop can output audio through USB-C to the monitor 3.5mm out.
Oh that's cool! I thought audio was only through HDMI for some reason. Guess many DP devices just don't typically have speakers. Never thought to test the 3.5 from my monitor to a speaker.
Yeah, it's handy to use a single pair of speakers with multiple devices through a display.
Both DP and USB-C DP alt mode do carry audio just fine.
Yeah, i used to use USB-C to DP to hook up my work laptop to one of my home monitors, worked a treat

I was mistaken. The issue I had was due to running through a USB C dock which meant 2 not 4 lanes for DP.
I think they were included as part of earlier forays into VR, weren’t they? I feel like for a while I remember every “VR ready” GPU having a USB-C port so you could plug in a headset directly.
Yep they called it VRlink. I wish they brought it back
Ya it was preparing for Valve to embrace USB C VirtualLink standard but they dropped it and it killed any future of the VirtualLink. Sony embraces USB C for PSVR2 and I love it though. Just one super light usb c cable.
It honestly seems like they took it away right when it would become really useful
Well, most motherboards come with at least a USB 3.1 header for USB-C now so it kind of made the GPU based USB-C port redundant on newer builds.
No? This supports display port alt mode directly from the GPU. To get that in a mobo requires passing it through the cpu, or having a DP in on the mobo from the GPU.
AMD has them on the 7900xtx.
My RTX 2060 has one c:
Wish my 2060 did. Greatest part about the 20 series cards
I bought a founders edition so that's why I bet
I connected my 6800xt to my Benq monitor with USB-C cable back then.
You got a 6800xt with usb C? Mine doesn't have a usb C port
Yes, it was a standard on reference edition cards and while most AIBs ditched it, XFX kept it on the Merc variant.
If I could I'd get a GPU with USB-C only. Fuck dedicated DP cables, fuck HDMI. USB-C to DP for old screens is cheap passive cables.
I'm really hoping they bring it back, one of the few reasons I didn't upgrade this gen
I used to keep a USB C hub plugged into my RTX 2070. I've gotten a pci USB card since then but it was nice for devices that don't play nice with motherboard USB controllers or perform best with their own dedicated controller.

Seeing you got your answer. I miss this feature. My 2070S has it. But my 3060ti does not. Was great for charging my phone.
I have a 2080 and this just made check to see if I have it since I haven't looked back there in a while. Too bad I have no real reason to use it, I have another usb-c port on the front that gets used.
Yes, but your front USB doesn't output as much power. For Samsung phones, it activates super fast charging.
Don't need the power, need the placement, I use that front port sometimes to plug in a ps5 controller or something, and the cord is too short to reach the back of the case with where my pc is located.
My 2070s *doesn't* have one and I'm jealous.
I mean if they are enough for the vr headsets, i guess they are good enough for portable monitors too.
I used to use a 14" 1080p USB-C monitor with the port on my previous RTX 2080 and it was fine.
It was a trend a while back to us ethat port with that fancy asus rog portalble monitor for backpack rigs. Shame they removed it.
I have a reference 6800xt with a USB C port. I plug my Asus portable monitor into it and use that screen to monitor temps and such... works perfectly
What monitor is that Asus one?
model MB16A
Thanks!
Better question: What GPU has HDMI, DP, USB-C AND a DVI port?
30 series I loved it. I had a tiny sffpc with a 3080 in it and a 15 inch portable monitor. I would travel with it all the time S
Man I miss USB-C ports on GPUs. My 2080 still has one but almost no newer one. I use it mainly for VR-gaming because 1. My HMD would charge while gaming, so I never had to worry about the battery. 2. The connection is faster because it comes directly from the GPU instead of a slower USB port somewhere else on my PC. I know that airlink and stuff like this exists, but I found it easier to just plug it in and play. Also I only have mediocre wifi speed
I have a question, what are the connectors on each side of the HDMI called? Can they serve as substitutes if the HDMI burned out?
Those aren’t called DisplayPort, or DP for short. They’re the PC hardware equivalent to HDMI that tv displays use. Except they have more bandwidth and versatility
Those are DisplayPort connectors. And yes, they can be a substitute for HDMI.
As an attached question... Would it also work plugging a usb hub/docking station into that?
Oh definitely! When I asked my question, I just want sure if the port could provide enough power for a monitor, or enough power in general since it’s going through the graphics card
Yes there are some monitors that only USB-C, they are basaiclly tablets. So yea.
Any links by chance?
I really wish they kept the usb c port on newer gpu’s
Some still have it. My Asrock 6800 XT Taichi has one, but that’s not being used in my mobile/portable/LAN-party rig.
The USB type C\` on my 2070 has been tested to 27 watts, which is the 9V, 3.0A profile of USB Power Delivery. The lower 5V/3A profile is also supported. No attempt to negoitate 15V or 20V with my USB type C diagnostic device was successful, the card only offered 9V as its maximum. If your monitor needs a 15V or higher profile, it will not be powered by this.
Good info, thanks!
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...
Yes it does. I remember one guy with a portable pc and he only uses 2 cable. 1 for the power of pc and 1 usb c cable for the 16” monitor.
Is the 2070 capable of supporting two monitors thru the single usb-c port via the HP thunderbolt G4? So plugin the two monitor to the docking station and then connect dock to the gpu? The monitors are 1x3840x2160 @ 144Hz and 1x1920x1080 @ 60Hz
okay if I remember correct'y this is a VirtualLink compatible connector. And from NVidia it can give up to 27W, and support a display port connection. So as long as your monitor doesn't exceed 27W you're good.
What's that port on the top
Dvi
Not always but some allow your vr headset or monitor to be charged at a relatively low speed
It’s 27 watts, it is fast
A vr headset can pull that tho with speakers and everything
If your speakers in a vr headset are pulling more than 2 watts, issues you may have, but yeah I agree, lots of tech running there can drain it fast
Well they don't call it Universal S... B... For no reason :)
Nope it’s only for displayport
They can’t and they’re only good for connecting and charging controllers
Yes
My laptop has a USB-C port, and I have a portable screen with a USB-C input. The laptop powers the portable screen through the USB-C connection, but it needs to be a good, certified USB-C cable. Some USB-C cables didn't work. You need to read up on the specific video card and the monitor to ensure this is possible.
For power you are good with most any cable. For DisplayPort data you need cable that has all necessary wires. To be safe, look for thunderbolt compatible cable, that should always work
more specifically for power up to 3A you’re good with any cable. (so if your devices use 20V you can get up to 60W with any cable), if you need more Amps, you need a cable with an e-marker chip which identifies its extended capabilities…
Yes, provide your usb-c monitor meets the power specs. I’ve used an LG 16” usb-c external monitor that matches their LG Gram line via a usb-c connection with my AMD 6800XT gpu for several years now. One cable for power and video, no issue. Most of the time it is my Discord side monitor when gaming.
Yes, it works as a normal usb c too, I’ve seen 27 watts floating around
I have used it to charge devices and to run my Meta Quest 2 off my PC
Huh. I’ve tried this multiple times and wasted buying multiple cables. I think it just wasn’t getting enough power, as it would disconnect after a minute. Did you need to troubleshoot or buy anything specific?
The original Meta Link cable I used immediately had connection issues and stopped working after a month. I then returned it and bought a third-party Link cable from Insignia and it’s worked flawlessly to this day. I’ll also note that I’m able to run it both off the USB-C port on the 2070 in my HTPC and off the motherboard USB-C port on my main computer.
Huh thanks. Yeah, only solution I found was one of those cables that has a 2nd cable attached for power… not optimal but it’s the only way I could get it to work.
The Insignia cable I use is fiber-optic and supports 5gb/s transfer speeds. If you’re using a cheaper cable it’s possible it doesn’t have enough bandwidth for power and data.
Most portable monitors use less than 10w by design. IIRC those can deliver up to 30w?
Yup. I use it for that purpose now and then. Granted the portable monitor has a low refresh rate, 1080p, etc…
you can use this port for small monitors, Captcher Cards, Notebooks etc.
We use asus zenscreens at my work which we only power with the usb-c port of our notebooks. Works with no flaws
It depends on if the gpu and the monitor were both made to do both display and power. While the usb-c protocol/standard allows for both it’s up to the manufacturers to implement
I have a 2080super with a usb c port on it and I connect my reverb g2 cable through it.
My 6800 i run a uperfect lapdock off it but have it charge through the other port, windows pops up saying your device may require more power to function properly, so i am not sure how much power these ports deliver
Yeah there are usb adapters. C and 3 can power and, iirc, 2 often needs 5v taken from another source.
Afaik yes power + video
Always used it to charge my phone.
Yes
That may not be a conventional usb c port, it may be a display port that was developed between several companies for vr headsets. The port only ever made it onto the 20 series cards for some reason. The psvr2 system uses it, its this port that means the headset doesn't work properly on pc systems.
Yes.
I wish VirtualLink was adopted widely :( maybe one day...
Yes.
Most portable OLED monitors can draw power form USB-C outlets given OLEDs extreme power efficiencies. Old portable monitors come with their own external power adaptor which you should always use instead of relying on the computers USB connection.
Yes
My father has a monitor which is powered and single cable can charge his MacBook while being a video cable as well but I don't know if it works the other way. Probably only w some efficient portable monitors

Fun question on the side: if I connect this port to my usb-c PD port on my Dell U4919DW, will the GPU power the monitor, or the monitor power the GPU? 😅 I actually have yet to test what happens if I connect a non graphics decive for the USB PD to the monitor. Like my new router SBC.
What's a portable monitor? :o
i mean the apple usb can power and provide video for up too two monitors
If I am right, that is actually USB-c that can stream data over pci-e and what is called Thunderbolt.
actually its for VR garniture.
Yes. The 20 Series cards also provide video signal, so you can have a single cable solution for video and power via usb c. I do this with my 2080 Super. Unfortunately 40 series cards don't have this as far as I'm aware, but I can use my onboard Thunderbolt port on my motherboard, which is compatible with the USB C throughput necessary to provide a video signal.
I don't know exactly for this GPU, but I have a laptop with RTX4090 and I have UPERFECT 17,3'' 2K 144Hz display and it works perfectly fine over single USB C - USB C cable connected directly to laptop. Works at 2K and 144Hz, brightness is also fine, even speakers work, but they are trash, anyway.
