This is good!  :D

Edit the section below by adding the PreferredMode line:

Section "Monitor"
    Identifier     "Monitor0"
    VendorName     "Unknown"
    ModelName      "LG Electronics W2253"
    HorizSync       30.0 - 83.0
    VertRefresh     56.0 - 61.0
    Option         "PreferredMode"   "1920x1080_60.00"
    Option         "DPMS"
EndSection

Save it, then check if you get a consistent result when you restart the DM, or 
reboot.

If it is still playing up you need to show the Xorg.0.log while the monitor is 
working with the nvidia driver, to see which Modeline it uses and add this in 
the "Monitor" section too, above the "PreferredMode" entry.

If none of this works reliably, then you have to capture the EDID table while 
the monitor is working, save it in a file and set nvidia-settings to use it 
hereafter.  However, if you will NOT be using this monitor for much longer 
this would be an exercise only to make you feel good for beating it into 
submission!  LOL!
