So today my computer needed a reboot and when it booted back up my resolution had changed. It used to be either 1280×1024 or 1400x900 I can't remember but now after fighting with the GUI display settings and the nvidia settings I have both set at 1024x768.

Here is my xorg.conf and xrandr just in case.

They are matching Acer AL1916W monitors. I think it's treating them as one but I don't know.

Can anyone help?
