I have a dual boot machine with Windows Vista Home and Ubuntu 14.04 just recently installed. It has a GeForce 6100 nForce 405 internal graphics processor. In Vista I can set my monitor to 1280x720 but in Ubuntu 1024x768 is the highest that will work. I use an Olevia OLEVIA 23" 720p LCD HDTV LT23HVX for my monitor. I know it says that the 1024x768 is the highest it can do on VGA but like said Vista will do 1280x720, I think even 1280x1024? Any help would be appreciated.

Please open this file

sudo gedit /etc/X11/xorg.conf

Find the section "device" and add this line to it 

Option"ModeValidation" "NoMaxPClkCheck"

Now reboot and see if your resolutions are back
