How to run a game across dual monitors?

[colinmstevenson]

Hello, I have a Hp Envy m6 Sleekbook and I recently purchased a Plugable USB docking station so I could run my new dual monitors.
I am trying to find out how to run a single game across both monitors as once as though they were a single monitor. the laptop has a AMD A10-5745M.
Most games I run are on steam but they only open on one monitor at a time. Is there a solution to this?

much thanks,

You need to configure AMD Eyefinity.
