How do you change screen size?

[ainsi22]

  After booting my laptop this afternoon, the screen size has become very small, almost unreadable for me.  The size of the pages are only about half of what they should be.  Can you help?

Right click an empty space on the desktop screen, choose 'Screen resolution' to change it. If that option isn't in right click menu, just choose 'Personalize'. In the window that opens look at left bottom sidebar for 'Display'.

My screen/image on monitor got narrower, the length is fine. How do I expand it to normal. Additionally I cannot move cursor arrow to eithe side to click onto black area. I can press 'Restore down/Masimize buttong" and right click onto back ground. HOW DO I RESTORE MY IMAGE BACK TO 'NORMAL SIZE' nothing works.

When i turned on my HP Paviliion laptop this morning, i noticed that the screen shrunk by 2 inches on both sides. Since this is a touch smart model, i tried to increase the screen size by touching the screen sideways. However, it didn't move a bit. I tried to look into the setting but am having difficulty finding the real icon to work it out.
