m15 R6, 3070, WD19TB, no video output

I have a Dell Alienware m15 R6 with Thunderbolt 4, running Windows 11 with all drivers up to date, including Thunderbolt driver, Thunderbolt control center, all drivers recommended by Intel Update Center and Alienware Update Center, all Windows updates are up to date, it's running on BIOS 1.6.0 (latest to date). And I have a Dell Docking Station WD19TB connected to the Thunderbolt 4, with the latest firmware, using an original Dell 180W power adapter.

On this Dell Dock WD19TB I have connected:

- 1 RJ45 cable

- 1 USB Hub with 4 devices connected to it: 1 headset, 1 keyboard and 2 mouses

- 1 monitor connected to HDMI port

- 1 monitor connected to DisplayPort port, using ELG 1.4 Ultra Premium cable

RJ45 and USB works fine, but no matter what I do, I simply CANNOT make the laptop recognize the monitiors connected to HDMI or DisplayPort in the WD19TB. If I connect the HDMI directly in the laptop, it works.

Bottom line is: Alienware m15 R6 does not output video coming from WP19TB dock.

ANY tips and suggestions are highly appreciated.

I had one DP Display Cable that did not work. If the first DP port does not work, all following ports will not work. So try another DP cable on the first port and disconnect the rest of the ports.

Best regards,

Thanks, I tried that but it didn't worked. I disconnected all video cables from the dock and tried connecting them one by one on different ports. Nothing works. Monitor says "No signal". Only when I plug HDMI cable directly into the laptop's HDMI port it shows video.
