To change the dimensions of your screen area in Windows:
1. Move your mouse over your desktop area and click the right mouse button.
2. Select the "Properties" option.
3. Click on the "Settings" tab in the upper portion of the "Display Properties" window.
4. Move your mouse to the area of the window that says "Screen area".
5. Move the mouse over the dial of the scale in the Screen area box.
6. Click and drag the dial to your desired settings.

Note: If you don't have the option to set the screen area to 1024x768 or higher, then your computer is probably old or not setup correctly.
