Envision Monitor XF86Config

This is for anyone with the same problem I had configuring /etc/X11/XF86Config for Red Hat 7.2-8.0 for use with the Envision EN-710e 17" monitor.
The flickering was fixed by setting the horizontal and vertical refresh rate to the settings below, after much trial and error.

Section "Monitor"
        Identifier   "Monitor0"
        VendorName   "Monitor Vendor"
        ModelName    "ENVISION"
        HorizSync    31.5 - 48.5
        VertRefresh  50.0 - 100.0
        Option      "dpms"
EndSection

Here is my /etc/X11/XF86Config
