BEWARE the 3090 Ti and WMR!

Recommended Posts

I was setting up my new Reverb G2 and the WMR setup failed with Error 1-4 (Device Cable Not Connected.) Microsoft’s AI bot ‘Emmanuel’ was no help at all.

I called HP and the tech I spoke to said the issue was the 3090 Ti and WMR not playing nice.

I hopped over to the nVidia forum, and sure enough, lots of people having the same problem, which seems confined to the 3090 Ti. The regular 3090 doesn’t seem to have this issue. He said it had to do with the Ti being a hybrid of the GeForce and the Quadro. Something something about the card doing some encoding that WMR can’t handle. Very frustrating.

A lot of time I’ll be skeptical when one vendor blames the other, but the nVidia forum seems to support his claim.

He suggested a ‘bandaid’ until nVidia or Microsoft comes up with a fix: Buy a DisplayPort 1.4 switch and a short DP 1.4 cable to go between the HP cable and the 3090 Ti DP port. Something about the switch fixes the problem for most of the end users he’s helped. I bought a DP 2.0 switch and a 0.5m cable for about $45 on Amazon. I’ll test it out next week.

I hope I don’t regret buying the 3090 Ti.

I had posted this link at various sites, some time ago. https://nvidia.custhelp.com/app/answers/detail/a_id/5382/~/compatibility-between-geforce-rtx-3090-ti-and-certain-vr-headsets

That eventually led here:
