How to connect 3 monitors on acer e1-572g i3?

Question

Video cards

Video cards:
AMD Radeon HD8670M and Intel
Processor: Intel Core i3 4010U 1700 MHz
There are two outputs: VGA and hdmi, in the characteristics of the video card there is information about the possibility of connecting up to two monitors. I'm going to connect 3: all three - Acer AL1917 It is
very necessary for working at home! + It would be convenient to turn off the laptop and take it with you. The laptop has not yet planned to change. So. I would like to know if there is some more or less cheap way to connect three monitors, each of which has its own image or part of the overall image (combining three monitors into one, so to speak)?
Any methods, reaching already an external video card, but it's a little expensive.
I heard about splitters, but they duplicate the image on all laptops.
Maybe you can replace the standard video card with some other one with three outputs?

Answer 1

two monitors through the laptop itself, the third through a usb video card (you won’t be able to play games, but it’s enough for text; the issue price is around $ 20-50, the Chinese may be cheaper).
