See if there is a driver
update available for your display adapter and if so, install it. Or, if not already installed, you may need to install a display driver that is specifically for your model laptop which should be available from the support site of the manufacturer of your machine.
Also, check the settings of your monitor (built in display) under "screen resolution," "display," when you right click the desktop, and see if there is a different one available in the drop down list to select that may be more appropriate. If the wrong display is selected, this could limit the resolutions available.
