How To Change Your Computer’s Screen Resolution

Here's how to change your screen resolution:

Go to your Windows XP's desktop and right click on an empty space. Select "Properties".

In the "Display Properties" window that appears, navigate to the "Settings" tab on the right.

Move the slider in the bottom-left corner of the window to change your computer's screen resolution: left for lower resolution, right for higher resolution. Try moving it to the far right for maximum resolution. Press "Apply" and see if everything works.
