A similar problem occurs with my MacBook Pro M1 13 inch. The HP Thunderbolt 3 Hub no longer outputs a video signal via the display port cable. If I adapt the same connection with a Displayport to HDMI adapter, I have a video signal again. This is really mysterious. My USB 3.1 capture card (AverMedia Live Gamer ULTRA - GC553) no longer works smoothly, even with a Thunderbolt 3 cable. Does anyone already have a solution?
