Q. Help! My cat walked on my keyboard and changed something. The text on my screen is large and fuzzy. And everything is stretched wider than it should be. Your picture on your homepage looks 30 pounds overweight! I can't figure out how to fix this. Can you help?

A. Well, either I need to hit the gym or fix your screen. The latter is probably the way to go. This sounds like a resolution problem.

You can do almost anything on your computer with keyboard shortcuts. So, your cat may have hit the right combination of keys. And now your monitor is all messed up.

From your question, I can deduce that you have a widescreen monitor. Generally, these monitors have an aspect ratio of 16:9. The old square monitors have an aspect ratio of 4:3. Your computer hardware and software supports both types.

Your cat mixed up your resolution setting. A 4:3 resolution on a 16:9 screen stretches everything out. Everyone on your screen looks fat. And your text is stretched and fuzzy.

So, you'll need to reset your resolution. Luckily, this is fairly easy. You didn't tell me what operating system you're using. So, I'll just cover all the popular ones.

In Windows Vista, right-click on the desktop and select Personalize. Then, click Display Settings. Use the slider to choose a 16:9 resolution setting. Click Apply. A pop-up will ask you to confirm the new setting. Click Yes. Then click OK.
