I know there is a bunch of topic about this problem, I've read most of them and nothing worked, so I create another one.
My setup : - Laptop used in dock and supposed to be VR ready ASUS ROG STRIX G15 G513QM-HN064T (AMD Ryzen 7 5800H / Nvidia GeForce RTX 3060 6 Go / Windows 10 Famille 64 bits) - Screen used on the laptop instead of the default one iiyama 23.8" LED - G-Master GB2470HSU-B1 Red Eagle (1920 x 1080 pixels / 165 Hz / HDMI & DisplayPort) - Oculus Rift (not the S)
Everything is up to date. Windows, GPU, CPU, Driver, etc When plugged, I have audio in the Rift. The screen stay off OR on but black if a VR apps is launched.
The Oculus app detect (most of the time) properly the HDMI plugged in the HDMI port while the monitor is plugged in the USB-C port. Absolutly no problem with the controllers and sensors. But the headset's USB detect my USB 3.0 as 2.0 whatever I do. Usually, I have 3 meters cables extensions for both USB and HDMI from UGREEN brand. I did every tests with and without those.
I'll not say much more about what I tested to avoid influencing your diagnosis.
The headset worked well with my previous laptop (Razer blade 15 late 2019)
