Probably not. If I understand it correctly, displayconfig-gtk writes a 
customized config file "/etc/X11/xorg.conf". If you use the xfix option, 
you get a default "/etc/X11/xorg.conf" without the customization. 
Therefore you undo the setting from displayconfig-gtk which is probably 
not what you want.

But after you have used displayconfig-gtk, you can have a look at the 
file "/etc/X11/xorg.conf". Actually I never used displayconfig-gtk, so 
this is more speculation. But from my Nvidia card I have a 
customized "/etc/X11/xorg.conf". In that file there is a line with the 
available resolutions. Mine looks like this:

    Modes  "1600x1200" "1280x1024" "1024x768" "800x600" "640x480"

The first entry is the resolution which is used as default, i.e. also for 
the login screen. Probably your line starts with the unwanted low value. 
You can change the sequence of the resolutions to start with your wanted 
resolution.
