I am on Windows 7 and use nvidia, my main Monitor is a Medion MD 20165, the resolution is 1920 x 1080 and I have 2 monitors. I want Age of Empires II to run on my primary monitor but keep the aspect ratio, with the black bars either side. I looked through various threads and came to a potential solution. This solution was to go into the Nvidia control panel and click "Use NVIDIA scaling with fixed aspect ratio" under "Adjust Desktop Size and Position". I went to this menu and no such option is displayed. I have attached a picture displaying this screen. This potential solution may not actually work as I am unable to try it, so also if you have any other solutions please say. Thanks
