In order to see the entire image with the best detail, your display should be set to 1024x768 or higher, true-color or high-color. If your display is smaller, information will be lost. If the color mode is lower, only limited gray scales will be available. Check the display mode by clicking on Start (lower left corner of screen) and selecting "settings" and "control panel". Double click on the "Display" icon. A set of tabs should appear along the top of the panel. Select the one on the right, labeled "settings". Drag the "Screen Area" slider right or left until 1024x768 appears. Click the pull-down arrow under "Colors" and select true-color or high-color. Then click "Apply" at the bottom right. If the display fails to switch to the correct mode, your computer may not have enough display memory. Other windows settings should not matter to the program.
