Latest amd-gpu-pro Driver on Ubuntu 16.04. Monitor = Viewsonic 22' FreeSync Monitor 1920*1080p Resolution. Model Number VS16261. Since Ubuntu 16.04 LTS is a stable long term releases I would recommend trying this with the AMD-GPU-PRO Driver versus trying Centos 7.3.
I am struggeling now for almost half a year with my graphic-configuration (ViewSonic VX2835wm, nvidia GeForce GTS 450). On a fresh install of Ubuntu 14.04 with the proprietary nvidia driver Version 331.38 (the nouveau driver doesn't serve any better) the edges of my screen are cut (overscan).
When I used Ubuntu 12.04 I could fix this problem. Back then I found out that the monitor sends bad EDID information. As a result wrong values were used for the configuration (Vertical Sync, Horizontal Refresh).
However, my old xorg.conf couldn't solve the issues under Ubuntu 14.04. I tried to implement it in many variations, but nothing really worked. Here is the old xorg.conf that fixed the problem under Ubuntu 12.04:
My current xorg.conf which proides the overscan issue looks like this:
Can someone identify the specific problem?

You can add Option 'UseEDID' 'False' and Modes '1920x1200'
to same sections of the new file.
Also
in 'Monitor' section may be useful.
But do not create duplicate lines. E.g. replace HorizSync 30.0 - 82.0 with HorizSync 24.0 - 82.0
