Connecting 2 external monitors

[RK]

Hello.

I currently have my laptop (HP Envy 14) connected to an external monitor via the HDMI connection. I want to connect a second external monitor and have the desktop extend across all three (including the laptop itself). Here is the documentation from my laptop:

Using ATI Eyefinity Multi-Display technology
Your computer supports the new ATI Eyefinity™ technology, which provides the following features:
● Allows you to use up to 2 external displays, as long as one of the displays is connected to the Mini
DisplayPort on the computer
● Provides a new display configuration by spanning the image across a group of external displays
into a single large surface (SLS)
What's new?
Example display configuration for single large surface (SLS)
You can use 2 external displays and span the image across them as an SLS. The 2 external displays are connected to the computer using the Mini DisplayPort and the HDMI port.
NOTE: Identical resolution is required between external displays to form an SLS. Displays with
different native resolutions can still form an SLS by using non-native resolutions.

Switching the screen image
Press the switch screen image action key to open a dialog box that shows the 4 configuration choices,
independent of the number of connected display devices.
[...]
● Extend mode—Extends the desktop to all connected external displays along with the computer
display.

1) Is it possible to show the desktop on all 3?
2) How do I get a monitor to connect via mini displayport, will there be compatibility problems?
3) My current external monitor is 1366 x 768. Going by the above wording, if I didn't get another that was 1366 x 768, I would have to scale one of them to a non-native resolution of 1366 x 768?

Cheers
