First right-click on the desktop and then left click on Properties from the menu that appears. The display properties dialogue box will appear, click on the settings tab at the top right of the box. This slide bar is what you use to change the resolution, the options you have will depend on your graphics card and monitor, but the standard options are 800x600, 1024x768 and 1152x864. Adjust the slider to the right for a finer resolution, adjust the slider to the left for a coarser screen resolution. Your monitor and video adapter determine how much you can change your screen resolution. You may not be able to increase the resolution above a certain level.
