Solved, I needed to swap the USB-Cs not all were going through the GPU. When I do set the adapter on the right port it works fluidly. Thanks for the explanation.

@VibrantNebula Thank you for your fast and detailed answer. Your support is greatly appreciated. If useful, the laptop is a Gigabyte Aero 15-x9. I don't have access to the Vive HMD today (I can post an update with it tomorrow), but here is the print-screen demanded, with 2 screens connected to the USB-C docking station. To my understanding everything is going straight through the Dedicated GPU. Shall I check something in the BIOS?

Hello, Thanks @VibrantNebula for your very informative post. I have nearly the same problem as @NightOwl. I have a state of the art laptop (with a Geforce 2070 Max-Q GPU, Intel i9, ...) with no displayport. However I live in Western Europe and the adapter suggested is not available anywhere close by. Could you please suggest other adapters that have been shown to work with HTC Vive Pro? Or a guide on the minimum specifications needed for it to work? In my case, I am sure that the issue comes from the adapter since I can use the docking station of my laptop as an USB-C to Display port converter and everything runs smoothly, but for the mobile platform (used to demonstrate the softwares that my group develops), the compact DP1.2++ adapter that I have purchased (https://www.digitec.ch/en/s1/product/club-3d-usb-c-zu-dp-10cm-notebook-adapters-5711550) doesn't work (I get huge image latencies even on commercial VR games running at 400 FPS on the laptop, based on GeForce Experience indicators). Thanks in advance
