VR - How to render second Cam to monitor?

Hi.

using Unity 2019.3.12f1, URP 7.3.1.

I use 2 cams, first for vr, second for a ui like spectator view:

1. cam is targeting: both eyes. I have to pick a Target Display (picked first, tryed second, tryed render texture instead…), actually i dont want to output the image to the mainscreen at all, just to the head mounted display.

2. cam is tartgeting: None (Main Display). Tryed first and second display… But if it shows up on mainscreen the head mounted display is all black, otherwise I get the vr view on both displays and the second view is in nowhere.

I never get it to the point where cam 1 is visualised on the headset screen and cam 2 on the Main Screen…

What am I forgetting?

Best

Did you find a solution to this?

Is the headset connected in Windows Extended Mode or (Nvidia) Direct Mode?

I didnt try it any further, because of corona we switched form vr to a three monitor setup.
