NVAPI NDA request


I represent the Montreal branch of TRU Simulation & Training.

I’ve been asked to post this here by customer support, could you please grant me access to the NDA NVAPI? I need to change the brightness & contrast of the monitor as part of my work.

Hi Mmitea,

Thanks for the post. We are circling internally to find you the right person.


Thank you, looking forward to getting access to it!

Hello Mmitea,

We have confirmed that there is no NDA NVAPI that can be used to set the monitor brightness.

However, you can use the Microsoft APIs to avail this functionality. Please refer to the following MS documentation for more details:

  1. https://docs.microsoft.com/en-us/windows/win32/api/highlevelmonitorconfigurationapi/nf-highlevelmonitorconfigurationapi-setmonitorbrightness
  2. https://docs.microsoft.com/en-us/windows/win32/api/wingdi/nf-wingdi-setdevicegammaramp


I’m talking specifically about the brightness, contrast, gamma and “digital vibrance” on the “adjust desktop color settings” page of the Nvidia Control Panel. I need more than just the Windows-provided functions.

Are you absolutely certain those 4 settings aren’t part of nvapi?

Hi Mmitea,

I have confirmed that those 4 settings are not part of NVAPI, our control panel uses the MSFT API.
