After spoke to technical support, I am returning my X17 R2 since there's no resolution on it.
  I have a Dell WD22TB4 dock connected to my Alienware x17 R2 TB4 port. Dell Alienware Onscreen Display prompt with below warning: A Dell Dock has been connected, some features are not supported by this system, please refer to the user manual for additional information. [IMAGE] When I checked with "Thunderbolt Control Center", I found no devices connected on TB port. [IMAGE] So I went to Windows 11 device manager, there's no Intel Thunderbolt Controller listed under "System Devices". My previous Dell laptop XPS 9560 has such device shown = [IMAGE] Further Google search led me to an interesting Reddit discussion [URL] It looks like the TB port is connected as USB 4 port and there's some issue on 12th Intel CPU. Just wanted to check if anyone else has notice the same issue?
