Hello All, I have one XPS 15 9570 with one TB 16 Dock Thunderbolt and it sometimes flash the screen in black for a second, this is the second unit I have... I replace the other thinking the problem was with my unit. I have the BIOS 1.10 and the latest firmware for the TB16, I also try with different watts the 180W and the 240W and the same problem. my workaround for now is disconnect and reconnect the USB Thunderbolt cable however I think this should be fix in some way. Firmware: MST1: 3.12.002 MST2: 3.12.002 ASM USB 3.0 Cntr: 10.11.A9 Dock NVM 00.00.27 Cable: NVM 00.00.16 Dell TB TI v1.2.11 Per Controller1: 01.02.11 Dell TB16 TI v1.2.32 Dell TB16 Dock EC Dell TB16 Cable PD 00.03.12 Any solution? I believe I’m not the only person.
