So you're going to run onboard graphics...

Of course not. Considering the price of the RX 480, I'd run one of those until Vega and then sell it off once Vega arrives.

Congrats, at least you're willing to try other methods to enjoy the HTC VIVE, until Nvidia can get that problem fix. Not like some, who have their vive collect dust, while waiting for Nvidia to fix that problem.

No, you should not have to do a workaround or return the product. There should be no issues with a DisplayPort capable product not working with a graphics card where each is supposed to support the other.

How come I can't follow you?

That's what I would do, because I'm stubborn and willing to stick it to a vendor like that even if it costs me money. The guy in the post already has his setup and there are currently no other high end alternatives, so the author of the article is pointing out to the public to push NVIDIA to fix the issue sooner.

 

It's still the issue of a $600-700 product not working out of the box, which is a problem. Not to mention people that buy prebuilts to use with the Vive, those people are already established to not be willing to run workarounds.

Sounds like a really weird issue. Since it is only a compatibility issue with the Vive my guess is that it is software related. If that's the case then a driver should be able to fix it. In the meantime, people will have to use the HDMI port or an adapter.

Not a big deal, but it should be fixed nonetheless.

not if it's a protocol issue since nVidia's GTX10xx uses DP 1.4

I can sense you're a stubborn person just by your previous post.

For prebuilts, don't worry about them, OEM have the power to do recalls and just return everything back to Nvidia.

While Nvidia is working on a fix, in the mean time he can run vive directly with HDMI or, return gpu and get something else like a RX480 or GTX 980Ti. Instead of waiting like a dumb ass.

 

Nvidia's official response

Quote

"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," said Bryan Del Rizzo, Senior PR Manager, Consumer Products.

Exact same thing I've said in the beginning, can't work now, try other methods to enjoy vive, while you wait for Nvidia to fix problem.

Aren't the display port standards supposed to be backwards compatible?

that's the idea, but minor differences can occur

I don't think HTC had access to a working DP 1.4 card before the VIVE launch

If it is actually a Display Port 1.4 issue then chances are it is up to HTC to fix this, as people are using 1080s with display port monitors.

 

Are there any reports of RX480 having issues with the Vive? Plenty of them have been sold, and that would confirm that this is a problem for HTC and not nVidia or AMD.

RX480 has DP 1.3, dunno exactly what revision but it's at least 1.3a

Ah OK, so we'll have to wait for Vega then.

DP 1.3 runs 4K at 120Hz and 5K at 60Hz.

Because they're being nice to AMD?

Nvidia is messing up like AMD is with the rx 480. It isn't as bad, but when you buy a card that expensive you can expect it to work perfectly, that's why this is being talked about.

Yeah, but if it is a DP 1.4 specific problem then a second party having issues with the HTC Vive would mean it is more likely to be HTC's problem, and the 480 doesn't have DP 1.4.

480 has the exact same DP implementation as Pascal

the difference is the nVidia advertises it as DP 1.4

and Radeon advertises it as DP 1.3 (with future 1.4 support when devices are available)

DP 1.3 to 1.4 is switched with a firmware, the 1.4 standard was finalized in a written form on paper only this year.

If you go into to the future to get a 1.4 device and bring it back, then plug it in - neither Pascal or 480 will work today, they both need update in the future

DP 1.4 runs as 1.3 if display do not support dsc.

While that's an option there should be no reason you can't use DisplayPort for the VIVE. Speaking of, why the hell doesn't it work?

Probably because the Displayport 1.3 (and eventual 1.4) standard is supported and orginal adapters are set to work from DP 1.2a. It is logical to assume DP1.3 has a higher pixel clock rate that is causing issues and not properly down clocking to give the correct hdmi passthrough for the vive.

It does, and this is what I assume is the issue. For whatever reason the displayport 1.4 connection is not recognizing the vive as a 1.2a compliant hdmi device and thus is trying to force some bizarre display output.

If it's hardware there are gonna be A LOT of pissed early adopters.

Yeah, if it can't be fixed in drivers I'll be a bit irritated that my 1400$ gpu investment can't properly play vr....

Fine print for GTX 1080's DP specs.

3 - DisplayPort 1.2 Certified, DisplayPort 1.3/1.4 Ready.

That is not true 4K, that's UHD, the so called 4K standard for TV .

Technically that's Cinema 4K, so go jump off a bridge

Ordered a Vive + 1080 in the same shipment over a month ago.

Still waiting on them cos they're both bobbing in and out of stock but are never available at the same time.

My mistake, ha

A friend of mine bought a 480 for his vive. Worked well
