How to resize desktop background ?

If your desktop is smaller than the dimensions of your monitor then follow the following steps to get a full screen:

Setting the resolution:

1) Right click on an open spot on your desktop and select Properties at the bottom of the popup menu.


2) This will then open up the Display Properties window as shown below.


3) Click on the Settings tab (it's to the top right of the Display Properties window as shown in the image below.


4) At the bottom left of the settings tab there is a Screen resolution heading with a slider bar beneath it.
5) Slide this bar to the left or right until you find the resolution you like.
6) The click Apply when you have found the right resolution.

Sliding the bar to the left = lower resolution, larger desktop icons and less quality.
Sliding the bar to the right = higher resolution, smaller desktop icons and better quality.
NB: If you are using a CRT (older screen) the max resolution will be around 1280x1024. Newer LCD screen (flat and thin monitors) can go way up to 1920x1080 and beyond if HD is supported.

NOTE: If when doing the screen resolution changes your screen goes blank after you click Apply then immediately hold down the Enter key to restore it back to your previous settings

If this doesn't work then it just maybe the case that you need to set the auto screen fit function on the monitor itself using the buttons provided on the monitor.

This tip is useful when you plug in a monitor and the screen displays the No Signal or Signal out of Range massages. Simply change the resolution to something the monitor can handle and there you go.
