Browser Setting for Fonts or Resolution. If you haven't set up the resolution for your computer, you probably need to. The default setting is probably low.
Recent computers have plenty of capacity for higher resolution.
It should be at least 800 pixels wide, even with the smallest screens. When you set up the resolution, you might notice that the desk top picture appears broken. That's because it is fixed width and doesn't go all the way across. That doesn't matter. Set up the resolution anyway.
