Text and Image in my LCD monitor looks fuzzy

My old CRT monitor is giving me a problem these past few days. I decided to replace it with an LCD monitor so I bought a new one from a computer store, I saw the monitor displays a clear text and crisp images but when I got home and setup the LCD monitor I noticed the text and images where not as good as it displays on the store. The texts and images looks fuzzy so I went back to the store and asked to replace it with another one. I set up again this new monitor and the results are still the same. I tried upgrading the driver of my video card hoping that it will do something with the new monitor and yet no luck. Any ideas about this? Thanks in advance!
