I am forced to top post as I am on the phone. I have dual boot on this
machine, with Windows 7, which works beautifully... no pun intended! This
is my computer for work so at this point I have not installed anything on
it, apart from Gnome, but this was happening with Unity as well. Seems
decent in terms of hardware, was just bought last week.

I have just tried to install the latest driver from Nvidia with disastrous
results, things were running in low resolution, mouse clicks were not
registered, couldn't select options from windows etc. Basically I broke it
:-)... I tried to put the old driver  back but that did not really gix
things. After a few restarts I put it back on the X.Org X but now it won't
pass the login screen. I might have to reinstall it...

monitor work when connected to something else ?

other distro if the monitors work and are connected correctly I  get 2
displays automagically using Nouveau .  Unless you are doing stuff like
running games it's been a long time since you "need" NVIDIA drivers, having
said which I install them anyway.

add ons dependent on which DE you are using.  Check Ubuntu help pages.

monitors work and are correctly connected you should find them and be able
to configure the screens to do what you want.  The days of having to write
xorg. conf files "should" be over unless you have legacy hardware.
