That's because you need to play the games on the native resolution. I mean, if you play games at 1024x768 on a 16:10 monitor which native resolution is 1440x900, obviously it will look bad. You need to set the emulator resolution to 1440x900.From my experience, games look worse on a LCD than on a CRT. That is just me.
If you have one of those HD like LCDs, I have no clue.

The same thing happens with 4:3 LCD monitors. A 15'' monitor resolution is 1024x768. Anything above or below this resolution will look bad (blurry).
