What happened?

Trying to use Full Screen on both monitors. I have tried with and without 3d acceleration, without success.
One screen is full screen with 3840x2160 resolution while the second will only allow 1920x1440 in the center of a 3840x2160 screen.
That's the best I've been able to get even using help from AI.

How can we reproduce this?

I am using the AMD Radeon(TM) Graphics on the motherboard.
