Computer screens vary greatly so that something that looks great on one screen, might look a little off on another. One thing you can do is to calibrate your monitor or laptop screen to compensate for different video cards, monitors, lighting conditions, etc.
To run the Display Color Calibration Wizard, click the "Start" button, and type "DCCW" without the quotes, and hit Enter. Now just follow the prompts to tweak your monitor to perfection.
