What display combinations are possible between IGP and Optiumus GPU displays?

The supported IGP display combinations depend solely on the IGP hardware and software. 0, 1, or 2 IGP displays can be enabled at a time. If the system also has a GPU display connector, up to one GPU display can be support. Between the two graphics adapters, up to three displays can be driver. The Windows operating system does not support clone mode across adapters, so only extended desktop mode is available across adapters. Clone mode is available between display on the same adapter.
