Pascal GeForces’ DisplayPorts don’t play well with HTC Vives

If you have a Pascal GeForce graphics card and an HTC Vive, it seems that trying to run the VR headset using the DisplayPort input on its included breakout box doesn't work right now. If a Vive is set up this way, the SteamVR software fails to detect the headset and presents users with an error message. Tom's Hardware broke the story yesterday after a Tom's editor's friend couldn't get his Vive working using a GTX 1080 and the card's DisplayPort output. We've confirmed this behavior with the HTC Vive and GTX 1080s in the TR labs, and it's worth noting that the issue has been circulating on the Steam forums for some time.

Nvidia's Manuel Guzman posted the following statement on the GeForce forums regarding the issue:

We are aware of user reports of an incompatibility when plugging HTC Vive into GeForce GTX 1080 using the DisplayPort connector. HTC and NVIDIA are investigating the issue. In the interim, we recommend users connect HTC Vive to the HDMI port on GeForce GTX 1080.

To be fair, running a Vive over DisplayPort seems like an uncommon configuration to us. It requires going out and purchasing a DisplayPort-to-Mini-DisplayPort cable, since HTC doesn't include one with the Vive. Still, users who want to run a Vive and another HDMI device (like a monitor or TV) all at once are rightfully honked. Perhaps Asus got lucky when it equipped its GeForce GTX 1070s and GTX 1080s with multiple HDMI ports instead of the three-DisplayPort, one-HDMI setup common on other Pascal cards.

    It is because Nvidia still refuses to implement adaptive sync in their desktops GPUs insisting on keeping Gsync 1.0 alive on ICU.

    [quote<]To be fair, running a Vive over DisplayPort seems like an uncommon configuration to us.[/quote<] The defacto monitor port is an uncommon configuration... I get that you used to put VGA on cards. And I get you put a HDMI port on it so you can connect a TV. But those 3 displayports on your modern gpu aren't for show. They are _the_ ports you should use for your monitor and VR headsets.

      Displayport is the successor to VGA and DVI standards.

      HDMI is the successor to the various A/V port standards. It was never meant to be a computer [pardon the silly pun] display port.

      Well, talking about the de facto (standard) for the VIVE, DP is not, instead, HDMI is. Does it mean you now agree with TR?

      I’d agree with you, if people were actually putting DisplayPort on cheaper monitors.

    I can confirm my Oculus is working via a display port to hdmi 2.0 adapter on my MSI GTX 1080 Gaming 7.

      • chuckula

      There was an assumption that the GTX-1080 has to be somehow incompatible.
      There’s no reason it couldn’t be the adapter in the HTC Vive that’s not quite right either.

    Pascal is an Oculus-exclusive too?! DAMMIT OCULUS!!!!!

    They need those high quality pixels from the Scorpio

      • tipoo

      The highest quality, uncompressed pixels anyones ever seen!

      What does that even mean…If they stripped the image compression out of Polaris that ain’t good lol

    I wonder if you will have to log in to download the new driver fix once it’s out??

    I get that not everything gets tested, but this seems like the kind of thing we as a community should have known about with all the reviews. Rather it’s a month later and no one noticed that a card with so many VR features touted only works with one of its many outputs? Kind of feel let down by the review sites on this and makes me wonder how thorough these tests really are. Buyer beware to be sure.

      • eloj

      I agree with your sentiment, but most of the touted VR features require software support which isn’t there yet anyway, which probably explains why no review I saw focused on it.

      • blahsaysblah

      Just goes to show how popular VR really is.

      [quote<]Rather it's a month later and no one noticed that a card with so many VR features touted only works with one of its many outputs? [/quote<] Yeah, how many GTX-1080 VR reviews have been posted online? Of those, how many used the Vive specifically instead of the Occulus? Of those that used the Vive, how many went out of their way to not use the default HDMI input but to instead use the displayport input? People tend to massively overestimate the VR craze's popularity. AMD & Nvidia love to talk about VR, but AMD literally never even demonstrated it at the Polaris launch and I sure didn't even consider VR when ordering my GTX-1080.

        I believe your questions are meant to be dismissive, but they’re cutting. Why didn’t most reviews do this? Why didn’t QA do this?

          • blahsaysblah
          • 4 years ago

          Because the Vive’s hub has standard HDMI port and a mini-DP port. Everyone has a regular HDMI cable, mini-DP to DP cables are not as common.

          • chuckula
          • 4 years ago

          You have a point: Why didn’t the [b<]HTC Vive[/b<] QA do this? People are just assuming that Nvidia, which does extensive testing of its displayport outputs, is at fault here. Nobody is even thinking that maybe HTC, which to my knowledge has never produced a product that uses Displayport before, could have done something wonky that isn't quite in-spec and that now maybe Nvidia will have to do something to Pascal that isn't actually required in the spec just to make it compatible with the Vive.

            Well there are only reports of a single video card not working with the Vive. So my default assumption is that it’s something specific to that particular card.

    There are comments on the nvidia forum that going into the motherboard BIOS and disabling PCIE UEFI boot fixed this issue for some users. Also, using a DP to HDMI adapter (if your lone HDMI port is currently filled up) and connecting the Vive over HDMI is also supposed to work.

    Glad to hear there are workarounds, and according to PCPer, nvidia is working on a fix for this issue.

      • benedict

      nVidia is working on a fix indeed. They are calling it the GeForce GTX 1180.

    • benedict
    • 4 years ago

    You mean nVidia made their DP out of spec? That’s inconceivable! I though only AMD could do such a thing.

      • biffzinker

      Don’t you mean Nvidia is artificially limiting (certified) their DisplayPort Connector to v1.2 even though it’s capable of v1.3/1.4?

        As in, not, but thry’ll just mention it/

      From what I’ve heard from a number of people that happen to own AMD hardware, this doesn’t mean anything. Most people won’t be affected, most people won’t bother to try, and even if there are problems, well most people shouldn’t be too bothered unless the problem continues for a great long while.

      Because things being slightly out of spec is fine as long as the hardware in question does not IMMEDIATELY catch on fire, ignite stray canisters of fuel, explode, and blow outward flames for miles in every direction, decimating school buses of preschoolers on their way home from seeing the latest animated movie involving animals that talk learning invaluable lessons of life about the importance of diversity and acceptance via pop songs sung by sellouts.

      Only then, according to some AMD hardware owners, can someone be upset that hardware is out of spec.

      And really, you only have the right to be mildly upset. Because this won’t happen often.

        We accept all specs. You must surely be a racist. And this is no mildly upsetting matter.

        • SiSiX

        What happens if it’s a school bus of kindergartners?

        Allowed to be upset then or only moderately annoyed? ๐Ÿ˜‰
