[Zenbane]

Beyond the issues of the Knuckles and their manufacturing defects, it looks like the HMD itself is suffering from some "sparkling" issues.

Those flashing images remind me of... umm....

I was getting that when i hooked this extension up. It went away when I took the extension off. Display ports suck. So ya it is a confirmed cable issue.

I  have see this on my Rift S sometimes when fiddling with the cable. I haven't seen this on my Index yet, so yes it's an issue that can happen to any headset with a bruised cable /connection.

So getting back on track,

It looks like 3 different related topics are being discussed on reddit about the issue.

Most signs point to a faulty cable. Someone else uploaded a video showing the Index sparkling.

My CV1 used to do that with an HDMI to DP adaptor before I figured out the issues to get it to work with the laptop via HDMI.

Could be the Cable.

Could just be a bad display port.

My CV1 sparkles when I extend the cable to long. If some are getting this on Valve index it could be that the cable is faulty, or possibly not enough juice going through the cable because of their Pc.
