I'm wondering whether or not having 4 external monitors on a Macbook Pro is possible? I know that Apple states that the limit is 2. But as seen on The Verge and Cnet it's possible to go further. On both links I see that the Macbook Pro is also displaying it's own screen.
So my question is, if that were to be turned off (lid shut), would I be able to drive another monitor? (In total, four 27" 1920x1080 monitors)
