Thank you so much Barbara, for clearing this up for me.

I was not aware of the fact that my PC, with GeForce GTX 760 graphics card was not able to display a simple screen in the right aspect ratio. Or maybe I'm not looking at the specs the right way ... On my former PC and laptops I never had this problem though.

Since there are no changes in the actual gameplay I'll keep playing my older versions of the games!

Thank you both, for your support and replaay!
