I unboxed my Samsung S34A650 34-inch curved monitor yesterday and plugged it into a Thunderbolt 4 port (USB-C port) of my Fujitsu Lifebook U7411 yesterday. It worked perfectly well for the whole day.
This morning when I turned on my monitor and Fujitsu Lifebook as usual. The monitor could not detect my laptop and it could only support the power charging and USB-hub function through the Samsung USB-C cable. I upgraded the firmware of the monitor to the latest version 1002.0 and installed the latest Samsung driver on my Fujitsu Lifebook, nothing worked. Please help. Thanks.
