How can I change the Digital color format via NVAPI


I’ve to ensure that “Digital color format” (NVIDIA Control Panel->Display->Adjust desktop color settings->Digital color format) is correct for the corresponding attached display (for HDMI displays it has to be set to YCbCr444).
I’ve tried different NvAPI calls but without success. Can someone provide me an example how todo ?

PS: used driver version Nvidia Quadro 307.74


I have a same problem too!

I tried NvAPI_Disp_ColorControl function, but do not works correctly.
And I tried NvAPI_SetDisplayPort function, It’s works correctly, but works only DisplayPort connection.

I’d like to change the “Digital color format” via NVAPI, Even when either of the HDMI and DisplayPort are connected.

Please tell me how to do.
