/etc/X11/sudo nano xorg.conf

The sudo is the superuser do command... you will need to use such as to change your xorg.conf file... the nano is the text editor... you could use the text editor of your choice...

Then you need the exact frequency of your monitor plus the resolutions as to fix your display...

Use the display section provided in the xorg.conf file as a layout but comment out it after you are done or you will have problems...

Good luck,
