========================
Detailed description：
Used a thunderbolt to displayport in the Dash F15 thunderbolt port to connect to the Reverb G2. Windows mixed reality app finds the Reverb G2, the displays turn on but are showing vertical bars. Items in screen are tracking, but no color, mostly vertical bars. sometimes the right screen does work.
I'm only testing through the Windows mixed reality portal.
It almost seems like it isn't using/activating the Nvidia 3070 card, since the graphics usage stays low and the dash doesn't get warm and the fans stay off.
The Reverb G2 works in my desktop computer with an ASUS 3080 TUF installed.

Hi trduff,
The converter you use for the Displayport to Thunderbolt, is simply port converter, right? or it is signal converter as well?
Thank you.

I can't post actual links, just realized they are both the same brand.
If I should use something different, please get me a link.

So they are active and signal converting.

I've discovered that if I disable the integrated GPU through the device manager I then get a 1-4 error when I try to start the Windows mixed reality portal.
So it looks like it is trying to use the integrated graphics instead of the nvidia graphics.
Any idea what to look at now?

Hi trduff,
We are suspecting it's a compatibility issue, but not sure it's because of converter or the VR device.
I will consult more to dig in.
The port on FX516PR is TB4, supporting DP1.4, while Reverb G2 is using DP1.3.
Do you have some simple adapter, just simply converting the DP port to Type C?
Maybe like this?
