Hi DeVillier,

Thanks a lot for the kind response.

For the above note this holds good for already installed OS.

In case if we are trying to install windows OS for the first time and GOP
driver is not loaded for the Intel iGPU in that case I understand there
will be blank out.

Correct me if I'm wrong.
