LCD Anti Aliasing Problem

Hello, I had been using a CRT monitor for sometime without a problem, I recently switched over to LCD and my Anti Aliasing while playing games is horrible. I'm aware LCD should be ran on their native resolution for best display quality, but this isn't the problem. Cleartype solved my AA problem on the desktop, but the problem remains when running games. Also, this is not a problem with a certain monitor because I have tried numerous LCD's. As soon as I switch over to the CRT the problem doesn't exists.

I run my games at 1280x1024, 6x AA, 8x AF.

crt's have a built-in advantage in regard to anti aliasing. adjacent phosphors in a crt have a tendency to "overlap" when lit up by the electron beams hitting them, causing slight variations in color. in effect what you get are color gradients leading from one pixel to the next. this is actually a form of anti aliasing and its free!
fixed panel displays cant do this since every pixel is compartmentalized with its own eminating light source. there are two sides to a coin though... since these pixels dont interact/interfere with eachother, colors can be noticably sharper and clearer.
