My HP Laptop can't use 3 screens at once

[Parmacoy]

Hello,my HP laptop is a HP Pavilion DV6-3010ax with a quad core AMD Phenom at 1.6GHz and an ATI Mobility Radeon 5650 with a HDMI and a VGA port. Now I tried connecting two external screens to it but it doesn't want to work. I can enable the two external screens but the centre one goes black, I can only use them in this combo. What can I do as the reviews say this laptop can handle 6 screens?

DV6-3010ax is a reseller config model, and doesn't support 6 monitors. It depends on the video card you have inside the laptop.
