Clicking on and off without pressing anything

Chances are somehow the screen setting options were changed. Go into the menu and try the different screen formats. Usyaully there are stretch and zoom settings. When viewing a non-HD station you will typically see black bars on the sides of the screen set the option to your preference.

Did you try 'stretch'?

on your desktop right click go down to properties click go to display go to screen resalotion and change it to fit your needs

Please give more details on what you are trying to do.

If you want to take a picture and make it the total size of your screen as the background of your screen, then just right click on the picture and select Set as Desktop Background. If the size is not what you want then go into the display properties and select the Desktop tab and change the Position to be Stretch. Stretch will fill the whole screen with the picture. Tile will fill the whole screen with multiple little pictures. Center will put the picture in the middle of the screen.

To get to the display properties click Start/Control Panel and look for Display or Appearance and Personalization.

You can also get the display properties by Right Click on an open area of the desktop and select Properties.

By not giving an accurate size, do you mean that everything looks stretched, is it not filling the screen, or is it cutting off the picture at the edges?
If it looks stretched or not filling the screen, you need to change the resolution of your screen. To do this in Windows Vista or 7 you need to right click on an empty portion of your desktop and click on "Screen Resolution." From there, click the drop down menu labeled "Resolution" and adjust it to something that looks right.
In Windows XP, right click on an empty portion of your desktop and click on "Properties." From there you need to click on the "Settings" tab, then move the slider inside the box labeled "Screen Resolution." Change it to something that looks right.

Windows 7 & Vista:
Right Click on your desktop and go to Personalization. Click on Desktop Background at the Bottom of the screen. On the Picture Position drop down menu, click Stretch and save changes.

Windows XP:
Right Click on the Desktop and click Properties. Go to the Desktop Tab. Select stretch from the drop down menu. Apply.
