Yes, it will. Problem is probably that the monitor is not correctly recognized.
The following is not from an Ubuntu box, but the principle is the same
Code:
Section "Monitor"
#DisplaySize 320 240 # mm
Identifier "Monitor0"
VendorName "DEL"
ModelName "DELL P790"
HorizSync 31.0 - 92.0
VertRefresh 50.0 - 150.0

EndSection
Section "Device"

The monitor section (at the top) contains two lines that define what your monitor can handle. Check you monitor manual and modify the lines.
Futher there are lines in the screen section that tell the system which resolutions can be used. It will default to the first one. If it can't handle it, it will take the next one.
The file involved is the X11 configuration file and can be found in /etc/X11. I'm not sure avbout its name in Ubuntu.
