Vive Pro HDCP Error

Hi everyone! Hopefully someone can help with with this really annoy issue I've been trying to fix for a couple hours.

What started happening today when I try to use my Vive Pro is that it will work totally fine for about 15-30 seconds before the headset display goes black.

 

The errors that come up in SteamVR are:

"SteamVR has encountered an HDCP error. Please create a SteamVR System Report for further info"

and then this comes up briefly before going back to the above message:

"Your headset's display cable has become disconnected. Please check your headset's connections and t...

 

Everything was working fine for months, I didn't use the Vive for a couple weeks, and now this.

 

Does anyone know how to fix this or where I could go to get some help? I tried doing the system report but I can't find where it give you any info about errors, it just gives me info about my system.

 

I've already tried:

  • Reinstalling Steam
  • Reinstalling SteamVR
  • Using the SteamVR beta
  • Reinstalling my NVIDIA drivers using DDU (I'm on the latest as of this post but have tried others)
  • Reinstalling my USB host controllers
  • Uninstalling the Vive USB drivers from SteamVR
  • Disabling the power management from SteamVR
  • Unplugging everything and plugging it back in
  • After getting pissed, installing a fresh copy of Windows 10 on another partition and trying from there

None of the above solved the problem. If anyone has any tips or can point me in the right direction I would hugely appreciate it since I'm starting to run out of ideas and can't find much online.

Since you already created the system report, could you upload it so I can take a look? You can PM me the link to whereever you hosted it. Make sure you check all the cables first. Unplug and firmly push them back into the ports.

Thank you,

Re: Vive Pro HDCP Error

Hi John! Thanks for your response!

 

I tried disconnecting all cables at both their inputs and outputs and still get the same error.

 

Here's a link to my System Report.

 

Hopefully with your help I can get this issue resolved, what's so frustrating about it is that I know everything works since I can get into Steam Home for 15-30 before the annoying error pops up and the headset goes black. @Synthesis

[NvAPI] HDCP EVENT: LINK LOST

 I think is where it's happening. NvAPI is the NVIDIA API, so I'm thinking it might be a driver issue. If you're updated to the current version, try rolling it back or reinstalling. If you're not on the current version, update to the current version. It might be worth just entirely reinstalling the NVIDIA software and updating from there.

Thank you,

Gave that a shot, I did clean installs of the latest NVIDIA driver (430.86) as well as a previous one I was using before this HDCP error started happening. Same error comes up every time.

 

Any other ideas? I'm at a loss

Sorry for the delayed response: I spent some time researching this and trying to find out if we've come across this before or if anyone has any idea why it's happening.

There's something we might have overlooked. Is it possible that your headset cable is getting tugged on and disconnected during play? That would also throw a display error. I was thinking this was a software/driver issue but you've addressed almost all of the possibilities by now.

Thank you,

Hi! Unfortunately I don't think the cable getting tugged on is the culprit (I've tried not even wearing/moving the headset and it still throws the same HDCP error after 15-30 seconds in Steam Home). I also took the little cover off headset to ensure the cable was fully plugged in on that end.

 

Another update is that I bought a new mini-DisplayPort to mini-DisplayPort cable and still get the same error, but at least it rules that cable out.

 

The only things left I can think of being wrong would be either the linkbox or linkbox to headset cable somehow died (but I wouldn't know how that could happen, I've never moved my Vive/linkbox since I first set everything up and there is no strain on any cables). 

 

Is there a way to disable HDCP or something along those lines? The headset clearly works since I can use it for 15-30 seconds so the frustrating part is that "High-bandwidth Digital Content Protection" shuts it down.

@hotsaucing 

It may very well be the cable. Unfortunately, HDCP is a copy protection method (that unfortunately doesn't work very well) that's built into HDMI, DisplayPort and other cable standards. It can't be disabled.

Are you able to get other devices to work through that port?

Thanks,

Re: Vive Pro HDCP Error

Thanks for your response! To answer your question, I have connected several other devices to the mini-DisplayPort output on my system and none of them have had any issues at all (including a G-Sync monitor that had been connected for at least 120 consecutive hours).

 

I guess I was trying to dance around it being the the linkbox/linkbox to HMD cable since I can't really find those online for sale and the ones I can find are pretty expensive/not from trustable sites. (Also I still don't 100% know if those are the issue since I have no spares to test, my friend has the regular Vive but both the linkbox/cable are different from the Pro)

 

Do you know if I could RMA or otherwise replace just my linkbox and cable?  I'd totally be willing to send my current ones in if needed, I just really want to be able to again use this device.

Hi,
Did you managed to find a solution?
I have the exact same issue on my laptop.

Its probably the cable. Try another one or replace it if you don't have a spare.

Re: Vive Pro HDCP Error

Hi,

Thank you for the reply, I tried replacing the DP cable but the issue remained. And I noticed that this didn't happen if I switch to extend mode.

Oh and I forgot to mention that I had to use a miniDP to miniDP cable, there's only miniDP port on the laptop.

Re: Vive Pro HDCP Error

@soraookami 

MiniDP to MiniDP is totally fine. 

It stops happening if you switch to Extended Mode? That's interesting. Direct Mode only is what's recommended but Extended Mode was left in for testing purposes. Is there another PC you can test it on? I want to rule out the device if at all possible.

Thank you,

Re: Vive Pro HDCP Error

I have a PC and had no problem with it .
Direct mode and extend mode are all fine on the PC.
