How Do I Change my Screen Resolution? - PC

Your screen resolution determines the number of tiny squares, known as pixels, which make up your computer display. A common resolution is 1024x768, which means 1024 pixels wide by 768 pixels high.

Increasing your resolution effectively shrinks everything on your screen, so that you can fit more on at once. In the same way, decreasing your resolution enlarges everything on your screen.

The screen shots below show you how to change your resolution in Windows XP, and the process is also very similar in Windows Vista and Windows 7.

Firstly, press the Windows key (normally the second-to-leftmost key on the bottom row of your keyboard) and D together to show your desktop. Then right click on your desktop and you will see the following screen shot. Click on 'Properties'.

You will notice that there are several options to choose from. Click the 'Settings' tab. When you have done this you will see (to the bottom right) the words 'Screen Area' with a pointer. The screen shot shown here is currently set to 800x600 pixels.

Try sliding the pointer to the right to increase the resolution, or to the left to decrease the resolution. If you have a good graphics card and monitor, you will be able to choose from many different resolutions.
After you have set the resolution you require, look to where it says 'Colours', there is a drop down menu with colour setting in it.

'True Colour 32 bit' is the highest quality setting for colours you can use on your computer. Not all computers will allow you to use this setting due to the quality of your graphics card. This is a matter of trying it and seeing if it allows you to do it or not. When you have the setting you require,  click 'Apply'. After a few seconds your new resized desktop will appear with the pop up window as shown here, if you are happy click on 'Yes'.

Then click 'OK'  at the bottom of the window to close the 'Display Properties' window.
