Docking Station not working over Nvidia card

Hi,

We recently updated some of our notebooks, which now have an NVidia graphics card.
After installing the Workstations, we realized that the Displays don’t actually use the NVidia card, but instead work on the Intel Integrated Graphics when connected through a dockingstation. We currently have the displays connected directly to the notebooks.
Changing the ports didn’t solve the problem (HDMI, DP, USB-C). The solution I found in different forums was to use Firebolt Docks. has anybody experience regarding this?

Notebooks: Dell Precision 7560
Display: Two 4k60Hz

Thanks

Hello and welcome to the NVIDIA forums! I am moving this topic from the Networking section to Hardware forum for better visibility.

Best,

Hi @braegger.remo,

If you check the specs for the Notebook you will see that the discrete GPU supports only USB type-C for external output, beside the standard ports HDMI and mini-DP. In this case they are also Thunderbolt 4 (TB).

To utilize these you can either directly connect monitors with USB-C (TB) input, or use a USB-C to DP adapter. There are special docking stations that can pass-through the DisplayPort over Thunderbolt signal and split it to additional DP connectors. The manufacturer specs should detail that.

I hope this helps.

Hi MarkusHoHo,

Thank you for your input.
We will try a setup through TB.

Regards

you don’t need to worry to much, gfx-heavy workloads ARE being directed to the powerful NV GPU, which will do the heavy lifting, and then copy its rendering results into system memory, for the Intel integrated GPU to scan this content out to the screen. SOME outputs MIGHT be directly connected to the discrete Nvidia GPU, you might be able to see this in the NV control panel, in the “Set PhysX Confirguration” option, showing (or not) physical connectors per each GPU.
You can also monitor the NV GPU usage to confirm it being used for the rendering…
If you want to be able to use special NV scanout features (say like Warp’n’blend) then the sink would NEED to be directly connected to the NV GPU, which not all Laptops allows for :-(.
