Try connecting the monitor, right clicking your desktop somewhere and pressing "Screen resolution", then pressing "Detect", then "Identify", and then sort the two monitors in the order you want them.
Got it working. :3
Now the only issue is to fit the monitor on my little desk.
I don't use Win7 so I am guessing: Right click desktop > Screen resolution > click the monitor you want to change the resolution of > click "Screen resolution" and move the slider up to the top?
Also disable DPI scaling ("Make items larger or smaller" or something it's called) by changing it to 100% rather than whatever it is set to now.
