Thank you very much for your post.
I understand that you have some questions on regards to the Intel® Wireless Display software.
Please note that this option comes available only if the OEM manufacturer (Samsung*) enables the option and complies with all the hardware requirements from Intel®.
If the system comes with the Intel® Wireless Display software already installed, you may try installing the latest drivers in the following order: Intel® Proset /Wireless software, Intel® HD Graphics drivers and Intel® Wireless Display software.
