Screwed up screen resolution on Samsung netbook

I have a new samsung netbook and recently tried to dust off the keyboard without turning it off and I screwed up the screen somehow now all my pictures and screen is stretched horizontally can't figure out what to do do I just reboot holding down the ctrl and f11 key as it says for the dell problem and restart not sure please help all my images are warped ty
 
Go to Control Panel > Display Settings, slide the resolution bar all the way to the right, and click "OK."

Hope that helps.
 
screen resolution? stretched

there is no 'display settings' setting and therefore no bar to drag to the right and press ok. CAn you be more specific and precise. what setting under the first heading under control panel?? thanks
 
If you are running XP, it is Control Panel > Display > Settings (this is a tab)

The window that pops up is called "Display Properties."

You can also get there by right clicking the desktop and choosing "Properties" from the drop-down menu.
