There is a bug in Snow Leopard that disables LCD (sub-pixel) fontsmoothing on many third party LCD displays, including models from Dell,Samsung, LG, HP, EIZO, and Lenovo. Here are the details:

Snow Leopard introduces simplified Font Smoothing options under theAppearance pane in System Preferences. Prior to Snow Leopard, the availableoptions were:

Automatic - Best for Main Display
Standard - Best for CRT
Light
Medium - Best for Flat Panel
Strong

In Snow Leopard, you can only choose between Automatic and StandardCRT. Since few people use CRTs these days, most users now have only oneoption: Automatic. The problem with the Automatic option is that OS Xincorrectly detects many third party LCD monitors as CRTs, and consequently,disables LCD font smoothing.

You can force OS X to use LCD font smoothing on all displays with thisTerminal command:

defaults -currentHost write -globalDomainAppleFontSmoothing -int 2

The number 2 here corresponds to Medium - Best for Flat Panel. You may alsouse 1 for light smoothing, and 3 for strong smoothing, as per theoriginal OS X font smoothing options.
