A few questions please, apologies if already answered.

For dual monitor set up do you need the same monitor model (same brand, size, etc)?

If I SLI two gtx 670s where should i plug in two monitors, 1 in each graphics card or 2 in the same?

If you SLI do you need the same brand of a graphics card?

What kind of VRAM would you need for two 22 inch + Monitors?

Thank you,

Thoughts about SLI and multiple monitors.
-SLI is intended to use 2 video cards to run 1 gaming monitor to get good performance.
-If you just want 2 screens for e-mail and stuff you can plug them both into one card and do not need SLI.
-SLI can play 1 game on the main screen and another task on the second screen.
-SLI can not have more than 2 screens.
-If you want to game on multiple monitors at once you need to enable surround(it is a type of SLI) Surround only works with 3 screens. And they all must match.

2 use the 2 screens for productivity like 1 game running and 1 excel spread sheet then the monitors do not need to match at all.
With SLI it depends on the card, but most times you plug both screens into the main card.
The brand...

The brand does not need to be the same. They just need to be the same GPU chip. Ideally speed and memory should match but it will work if they don't. SLI will operate at the lowest common numbers.
Vram is about resolution and the type of programs. 2 screens at 1920x1080 will run fine on anything 1gb and up.

With that laptop you can use the built in screen and 1 additional screen. The 2nd screen can be a mirror of the laptop screen or it can be an extended desktop.

A 3rd screen would only be possible with a USB video adapter. Those are ok for static images and basic typing but do not work to well for video.

The HP website does not mention display port. It states you have a HDMI and a VGA. Normally you can use 1 or the other but not both. I don't see any mention of how many monitors on the HP site. The ability to use both ports at the same time is not typical, but possible depending on how HP has the board setup.
