What kind of output do you get if you use the interactive mode of simply using displaymodeselecotr --gpumode? It should show you all available modes.
Also, for Windows, you will need to change the driver model from TCC to WDDM as well by using nvidia-smi. Check the documentation that comes with the displaymodeselector tool for more details.
Regarding windows, I think the doc says first to change the gpumode to “graphics” and then do thing to the Windows Driver… No?
(this is the smi output with everything default)
Regarding the order of use of the two tools I think this is interchangeable.
But looking at your output I am at a loss right now as to why this does not work. I’ll reach out internally to get more eyes on this and how to debug further.
Hello, I also have the exact same issue with this card. Followed the docs to a T. Tried on both windows and linux installations. Each time it says that the A40: "Specified GPU mode not supported on this device 0x2235)
The updated version is 1.6.0 with full Ada support and should be available for download now. This is a “on-request” tool, so either use your existing download link or follow the process here.
@MarkusHoHo , Same error.
What is this error about?
Thanks

I worked with an senior NV tech guy and while he did changed the mode, the cards never worked as stated in the manual or the specs (I was testing windows in my case).
I have a L40s and have a similar issue. I set it to physical_display_enabled_256MB_bar1 and also tried 8GB. and then in windows used did nvidia-smi.exe -fdm 0. Now I get 4 displayports in topography view but they all say not connected even though there is a working display port connection to a computer screen (tested with a 4060).
Datacener GPUs default to TCC mode, not WDDM (windows only). Those datacenter GPUs supported by DisplayModeSelector Tool can be toggled into WDDM mode… which can turn tricky, if there is not a single GPU in WDDM mode, for windows to run its desktop on :-(. But if you get to windows desktop, run nvidia-smi (post output here), check if the GPU in doubt is recognized, and if yes, if its in TCC mode. if yes, use nvidia-smi to toggle it into WDDM mode, then it should work for attached screens and desktops… the (actively cooled) workstation RTX cards default to WDDM, the datacenter GPUs (passive cooled) default to TCC mode…
