Hello

I have 2 L40 GPUs on Windows 10 Enterprise host.

I want to change the driver model to WDDM from TCC.

First, I tried NVIDIA Display mode selector to change GPU mode th Graphics.

But the second one of L40 GPU cannot be changed GPU mode to WDDM because of “not supported”

and then I tried “nvidia-smi -fdm 0” to change drive model.

One of the L40 GPU can be changed to WDDM after reboot, other one could not change the model because of “not supported” message same as display mode selector.

Installed NVIDIA Driver version is 538.15.

Thank you.
