Does Intel Embedded Graphics Drivers support sharing of I2C bus across multiple DVO/SDVO devices?
Yes, but the “Data Address Byte” of the sDVO devices should be different. Check the Intel Embedded Graphics Drivers User’s Guide for more information how to configure them. Please note that for two transmitter support it is critical to specify the I2CDAB hardware address option in the configuration for each one. Typically sDVO devices will be found on port 70h and 72h but your hardware may vary. In CED, the configuration option will be found on the sDVO Configuration page under the “I2C Settings” button an the I2C Bus Configuration section. Specify your addresses in each device’s “Device Address Byte” box.
