--- Comment #19 from Joao Pimentel <joaofelipenp at gmail.com> ---
This functionality is probably contained by the intel driver, but I don't think
it is contained in a default intel driver.

When I updated the windows to 8.1 just after the release, the second screen
stopped working. I had to downgrade the intel driver to the intel driver
provided by asus to make it work.
