I2C read and Write with Optimus Technology

Hi

We are using the Samsung Laptop (SF510) with Optimus graphics card for DDC/CI communication with Monitor.

We are using the MSAPI for I2C read and Write.

but we are getting the error which accessing the I2C line using MSAPI.

The Laptop having following cards

1. Intel(R) HD graphics

2. NVIDIA GeForce 310M

by default the Intel card is active.

Please let us know how we can use the MSAPI or other method for accessing the I2C line in case of Optimus technology graphics cards .

Thanks and Regards

Sushil
