Please help.  My neck is breaking because I accidentally turned it horizontally and ccan't change it.what video card manufacture you haveWelcome to the CH forums.

http://lmgtfy.com/?q=Rotate+screenI don't KNOW anything about the video card just that it is Windows XP that I am using on a HP vavilian a705w.  Where can I find the information. Thanks.You didn't say what operating system you have.  The LINK that Dusty posted works for XP, but does not work in Win 7.  In Win 7 you need to go into display settings and you can change it there.

I think MS changed it from XP to Win 7 because so many people accidentally hit the wrong keys and ended up with the screen you have now.  I've heard  stories of cats working across the keyboard in XP and changing the screen.GOT THE ANSWER!  THANK YOU.   After looking at all of your comments I ended up right clicking the desktop screen.  When it opened up, it opened up to Graphic options.   The window then opened up to rotation options that INCLUDED 90%, Normal, etc.

I hit normal that had a picture beside it of a normal vertical screen.   THANK YOU.  I am up and running.  I will stick with this forum.

it is great.I Voted...
