Which distro? Version? All aren't configured exactly the same. Are there other files in /etc/X11/xorg.conf.d/ affecting graphics configuration? /etc/X11/xorg.conf?
Did you try putting an xrandr script in an appropriate location for your distro in /etc/X11/?
Section "Monitor" Identifier "DefaultMonitor" HorizSync 28-85 VertRefresh 50-100 Option "PreferredMode" "1920x1080" EndSection
Try above, after editing HorizSync and VertRefresh to match your display specs. If that doesn't help, try 2560x1440 or 2048x1152 instead of 1920x1080.
This leads to a non-booting system (error message about Plymouth failing). If I manage to boot to a command line, startx does not work, complaining that "Identidier" is not a correct command.
Try disabling Plymouth. Add one of more of the following to your linu line in Grub:
noplymouth plymouth=0 plymouth.enable=0
If none work and your distro allows uninstalling plymouth, uninstall it.
If still no joy, try a totally different approach, creating ~/.Xresources, or /etc/X11/Xresources, and appending to it:
Xft.dpi: 132 or Xft.dpi: 143
With this method, be sure your desktop settings fonts panel does not force a dpi.
If you try more than 143, you may get undesirable side-effects.
