multiple monitors

There are more than 50 computers that bear the name MacBook pro, released over more than a decade.

¿which is yours, including year and screen size?

what ports are available to use for this adventure?

That appears to be a DisplayPort display:

1 VGA
1 DisplayPort™ 1.2
( with HDCP support )

.

That model MacBook Pro supports its built-in screen at 1440 by 900.

It also contains Hardware to support ONE external Mini DisplayPort display at up to 2560 by 1600. Both internal display and external display can be used at the same time, and can be concatenated along ANY edge to create an "Extended Desktop".

Converting the Mini DisplayPort to VGA is nonsense -- it only serves to degrade the display quality and refresh rate. A [Mini] DisplayPort to [Full Size] DisplayPort cable should not be expensive because it is just a re-wire, no electronics inside.

To add a second external display, (which will NOT have graphics acceleration, and will be a bit slow to update) add-on solutions require two parts:

• the obvious stuntbox with some sort of display output connector. These usually connect via USB or some other data port.

• the required software that creates and manages a "software Display Buffer", and sends it out to the stuntbox, such as the built-in Drivers for your external box, which may already include third-party software such as DisplayLink software.

this is an example:
