Running 2 monitors with one slightly smaller height, but trying to get them to same resolution? help?

[PedramCarter]

Right so play league of legends and trying to get it to run on 2 screens for more stuff to be displayed, one has 900 height while the other has 760, this means that i have to make the other one smaller which looks retarded because when i run across with my pointer to different part of screen it jumps down, I heard that you can exceed and overide and increase your maximum resolution somehow on on Nvidia but on my r9 290x check AMD catalyse it doesn't give me the option?
I can drop to 700 height resolution on both screens but then it decreases quality.

You can only match the lowest common denominator, you can not increase the resolution of a screen if it does not have the pixels to do so.

No matter what you do it's going to look weird, you need two monitors of the same size and resolution.
