i want to manipulate some monitor settings via ddc. I assumed that the right function to do that is NvAPI_I2CWrite()? If that’s right i have some questions about the parameter NV_I2C_INFO * pI2cInfo:
How does the data in the buffer NV_I2C_INFO_V3::pbData need to be structured? I know the vcp code the value i want to write.
I’ve set the NV_I2C_INFO_V3::i2cDevAddress field to 0x6e << 1. I assume that shouldn’t touch the first bit which might be set by the function NvAPI_I2CWrite or NvAPI_I2CRead?
What is the NV_I2C_INFO_V3::displayMask? Is there a nvapi function i can call to retrieve that mask or is it the number displayed by windows on the monitor in the display configuration?
I am using the NVAPI version of September 2012.
