Which version of UE4 do you see the issue?

Hi yes, I can connect with you to discuss. Thanks for reaching out.

Were you able to get the updated vbios from MSI? In the meantime, you can roll back to the older NVIDIA driver version 417.xx which should work until you are able to update the bios.

You'll need a miniDP to miniDP cable. There are no HMDI adapters or active converters that will work. But in the case above, it's related to the MSI vbios update.

In my experience, Best Buy typically does not have this cable in store. Your best bet is probably to order from Amazon.

@Kay2029 Congrats on your awesome gift! This miniDP cable will 100% work with your new Vive Pro: https://www.amazon.com/dp/B0777RKTJB/ref=twister_B077GCMQXJ You will need a miniDP to miniDP cable to connect the Vive Pro to your laptop. HDMI cables or adapters will not work with Vive Pro. Let us know if you have any other questions.

@KDM I sent you a direct message and would like to know more about your application. Thanks.

@keller Have you tried the solutions here: Please check out that troubleshooting guide and let us know if you are continuing to experience the issue. Thanks.

It's supported in the current release https://assetstore.unity.com/packages/tools/integration/steamvr-plugin-32647 @Schell Games

wrote: Hi David - Thanks for the suggestion! Unfortunately, I tried this process and things are getting worse. Here's the play-by-play: 1) To start, I had the HMD disconnected and performed the reseating as shown in the instructions. 2) After connecting it to the linkbox and booting up the computer, the video stream was working at first. 3) As soon as I rotated the harness hinge a little bit, the video stopped. 4) I reseated the plug again to see if it would restore the feed (while still connected to the powered linkbox) Now the linkbox appears to be dead as well - the green light won't come on and the PC no longer recognizes it when plugged into any USB ports. As a test, please swap the hmd cable from your working Vive Pro to the Vive Pro with the issue. It may be a failed cable and this would help to confirm it. Please also ensure you are using USB 3.0 from the link box to the PC, not USB 2.0.

wrote: I've had this problem as well that was resolved by swapping USB ports from 3.0 to 2.0 (and ultimately swapping mainboards so that I could go back to 3.0). Yes be sure to use USB 3.0, not 2.0.

wrote: Hi, I am unable to download the SDK from here - https://developer.vive.com/resources/knowledgebase/vive-srworks-sdk/ as the link reports an error. Is there another link available? Thanks, the SDK download issue was addressed. Let us know if you need anything else to get started.

wrote: Hi, How can I get early access to this SDK, thank you! You can access the SDK here under PC VR: https://developer.vive.com/resources/

wrote: Update: Installing SteamVR did not solve my problem. I did try installing the UE4 with the SDK on another computer which, apart from having a 1060, is very similar to the computer I'm having the issue on and had no issues with it. Based on this my working theory is that the (lack of) nvidia card is key, but can't say for sure. Yes it requires NVIDIA. You'll need access to a VR ready PC or laptop with NVIDIA card.
