Hi, for a long time my TB4 usb C hub has worked amazingly. I work on a laptop and have to plug in a monitor with a displayport to usb c and an Oculus Quest 2 headset for work. Recently my monitor stopped being detected when it was plugged into the TB 4 dock but works perfectly when connected directly with my laptop. Though it’s functional it’s not ideal since I can’t connect both my display and headset at the same time. I just installed the latest bios update from dell via the alienware updater but unfortunately it didn’t seem to fix the problem.
My display will active when I first plug it into the hub like it is receiving a signal but it never actually gets the feed from the PC and eventually goes back to sleep.
