Lack of Fuzzy Logic

Hello, tech support.

Hello, I've got a problem with a monitor I bought from you folks.

What seems to be the difficulty, sir?

The thing is only a year old, and the screen is so fuzzy now, it's hard to make anything out on it.

Have you tried adjusting the contrast settings?

I tried every knob and button on it. Nothing helped.

Well, before I write up a repair ticket, we can try one more thing.

What's that?

Sometimes, they can attract quite a bit of dust. Have you tried cleaning it?

Cleaning it? Hold on a minute. Â….Well I'll be damned. Looks good as new.
