What's wrong with my computer screen?

Question

One of my other crt monitors just died, so I swapped it out with another

one that I had laying around. And Now when I wake my computer from sleep mode the screen goes all Blurry and I can't see anything.

But when I restart it it comes back to a clear picture. What could be wrong.

By the way the monitor is an acer crt and the computer is a new emachine. I only had the computer for about a week now.

Any help would be appreciated.

Thanks in advance.
