How do i adjust size of desktop bac...

If you are using Windows Vista right mouse click on an empty area of the desktop and select personalize. Click on the tab for background and there are options there to fit to screen, stretch image, tile, etc. Select the stretch image and then apply. It will make the image fit your entire desktop. If you are using Windows XP it would basically be the same steps exceot when you right click you would select properties. Hope this helps.

Locate the display menu keys on your monitor's body. Open the menu and you will find options to make the screen smaller or bigger, thank you.
