This is my first post here and hope I am following the rules of the forum.
I reviewed Connecting 2 External Monitors to a Laptop? and confused with hardware terminology to figure out if my Dell Precision requires additional hardware or additional software or just some configuration.
I cannot make Linux(centos 6.5) connect to 2 external monitors. I was able to connect to 1 external monitor by running
$xrandr --auto --output DP-0 --right-of LVDS-0
Here are the display properties
$xrandr

Edit
I tried the following commands (and nothing happened)
$xrandr --auto --output DP-0 --right-of DP-2
Here is the info on the vga card

Can I connect to 2 external monitors and extend the display just by configuring? If not, what is the reliable/easiest hardware/software I have to buy
****EDIT****
-Model is M4600 (Dell Precision); complete specs are here (I assume my laptop support all these) http://www.dell.com/downloads/global/products/precn/en/precision-m4600-specsheet.pdf

-There is HDMI port (behind); I work for startup (so hopefully what I have is business grade); could not figure our display port (but let us assume it there)
-Also I am using docking station where my 2 monitors are connected to (I tested 2 external monitors working on this docking station from a DIFFERENT windows laptop and I am trying to do it for this centos laptop now)
Can it be as simple as a centos shell command to hook up the laptop to 2 monitors (if so what is that command)
