This laptop has allready many issues related to graphics due to some sort of conflict between Intel HD and AMD Radeon wich gives problems to switch between the two graphic card. Although it seems a driver issue, getting them to work together efficiently is very hard.
Intel HD3000 and HM65 chipset clearly says that only two monitors are supported.
Hi Simius, thanks for posting! Thanks for the great detail you provide regarding the elements in your system. Unfortunately, I would not recommend our dock or adapter for use with your system as configuration with an older dual graphics system (also known as a hybrid system) that you mention is a bit finicky already. Our dock and adapter run the DisplayLink software in order to work and we have seen undesirable behavior on some systems with a hybrid graphics setup. Theoretically, our dock and adapter would be able to add additional monitors to your setup but due to the description of the system, I would not recommend our DisplayLink products. I do apologize fi this seems negative, but we like to set expectations to mitigate potential issues in the future.
That being said, and if you do choose to proceed with a purchase, we offer a 30-day no hassle return policy via Amazon.com if you find that our adapters do not meet your needs.
