That`s because you have to load the monitor profile file.
That tells windows what the maximum screen resolution of the monitor is to windows and the available refresh rates the monitor can support at different resolutions. Normally it used to be the case if you were using an old Crt type monitor with say windows xp you would come across this problem. Just take a look on the back of the monitor take note of the manufacturer and the monitor model number then do a google srearch with the details and put monitor profile.
You need to load the video drivers, if you only have the default Microsoft driver it will not see the plug and play monitor. When you load the correct video driver then it will auto-detect your monitor.
