Can I use 3 monitors on a laptop with AMD Radeon HD 7570M?

Question

Iron

I have an HP ProBook 4340s laptop with an AMD Radeon HD 7570M discrete graphics card . The laptop also has a built-in Intel HD 3000 video card. Both video cards are visible in the system properties, but only the Intel video card can be controlled, and the AMD program only does an incomprehensible function “increasing performance for selected applications”. In the settings of games (for example, Skyrim), only Intel is visible. When connecting two monitors (in HDMI and VGA), you cannot turn on both monitors and the laptop one at the same time, but because everywhere in the settings there is a mention of only the Intel HD 3000, then this is logical - it only supports 2 displays, but AMD supports up to 6 displays.
How to enable all three displays? How to force enable discrete graphics card?
PS. In BIOS, you can only disable / enable a discrete graphics card, there are no other settings.

Answer 1

now I tried to boot into SUSE Linux, which came with a laptop - it also allows you to work with only two monitors, despite the fact that it is selected to work with AMD video in the settings. And the choice itself is much more obvious - you can immediately see which card is currently working.

Answer 2

Just in case, I throw in a link to USB video cards.

Answer 3

I wrote here that this configuration did not work on my HD5650, there are built-in and discrete graphics from AMD.
But here Silver_Clash works. Apparently it depends on the model.

Answer 4

“Thanks to Eyefinity, the graphics chip is theoretically capable of driving up to 5 monitors simultaneously. However, this only works if the laptop has enough DisplayPort outputs."
