I have a DELL XPS 13 9310 laptop which only has 2 thunderbolt 4 ports so I wanted to connect it to my Alienware 38 Monitor AW3821DW but every hub I bought from Amazon didn't work at the advertised 4K/60 hz, only at 30 hz until I found this USB-Hub: https://www.amazon.ae/gp/product/B09CPJV3B4/ref=ppx_yo_dt_b_asin_title_o01_s00?ie=UTF8&psc=1

It is from a company called CableCreation and finally, it did work with my monitor and did support the 60hz refresh rate. It works perfectly fine but the issue with it is, if I shutdown my laptop, when I turn the laptop on again, the monitor detects no signal and stays in stand-by mode. I tried turning the monitor on and off but it still won't detect any signal until I unplug the hub from the Thunderbolt port then replug it in, the screen would work right away. Restarting the laptop does not have this problem it's only when waking up from a cold boot.

I tried disabling PCIe link power management in the power options but that didn't help

Any ideas?

PS: I do have an Apple USB-C to HDMI connector and that works perfectly fine even if I shutdown the laptop the issue with it is it has only 1 USB connection and the other thunderbolt port is occupied by the power adapter

I don't have a solution for you but I have a very similar issue with a usb hub where I keep an external hard drive attached. The hard drive is not detected until I either unplug and repIug OR open disk management and let it scan for the drives. Even though it is a powered hub (the external hard drive is also powered) I believe it is somehow related to the way my Dell PC scans for new hardware on restart or boot. I've spent hours and still haven't been able to find a solution but I made a shortcut on my desktop to open disk management at which time it's immediately detected when it scans for drives. The same principal may apply to your case.

Instead of unplugging and replugging, do a little test. Go to device manager, right click on 'monitors' and select scan for hardware changes. See if it is detected then. I'm very interested to know if your case is like mine.
