Intel Chipsets or video cards have demonstrated to have resolution problems in a very common pattern. To solve this problem, please follow these steps:

1.- Search the values of HorizSync and VertRefresh of your monitor.
2.- Open a terminal and type "sudo X -configure :1" without quotes. This will create a new xorg.conf file.
3.- In the same terminal, type "gksu gedit" without quotes. This will open a text editor with the file that you have just created in there.
4.- You will see that it is divided in sections. Search for the Monitor section, and before the EndSection line of that section, add this two lines, without quotes:
"HorizSync 30.0 - 81.0
VertRefresh 56.0 - 75.0"

5.- Replace the values in there with the values found in step 1.
6.- Save and close the file. If you want to, you can put it into a pastebin so I can check it before you move. If you do not want to, then move on to the next step.
7.- In a terminal, type "sudo mv /etc/X11/xorg.conf" without quotes. This will move the file to its correct position.
8.- Restart the PC.

In case it does NOT works, copy this command into a paper: "sudo rm /etc/X11/xorg.conf", and boot into text mode, to enter this command without quotes and remove the file. If it works, please ignore this step.
