Font smoothing - OSX doesn't detect my screens as LCDs?

[Kasakka]

I just noticed that messing with the font smoothing options I get the best image quality by using the "Standard - best for CRT" option. If I use the "Light", "Medium - best for LCDs" or "Strong" options then especially bold text is noticeably blurry by comparison. So gathering from previous threads it seems that OS X thinks both my monitors are CRT screens.

 

In another thread someone mentioned a plist hack where I could force the screens to be detected as LCDs and it seems that I have to do this to get the font smoothing working right. Can anyone tell me how to do that or if there's some other solution to the problem?

 

It's especially noticeable on bold text and around 12pt fonts, definitely worse on black background with white text.

Images showing the difference:

 

Picture1.jpg - using "Standard - best for CRTs"

Picture2.jpg - using "Medium - best for LCDs"

 

As you can see the Picture2 looks darker and stronger but at the same time less crisp. It seems almost like the Medium setting throws more antialiasing on top of the standard setting which is already antialiased to begin with. It seems that turning off font smoothing doesn't work either because the "Turn off smoothing for fonts under x" when set to 12 pt shows no difference. Also using the Automatic setting definitely selects the "Standard - best for CRTs" option.

 

My system:

OSX Leopard 10.5.4 (Leo4All V3 + JaS 10.5.3 combo update)

Viewsonic VP2130 (S-PVA, 1600x1200, 21") and Lenovo L220X (S-PVA, 1920x1200, 22") monitors

GeForce 8800 GT 512 MB (using NvInject)

Intel C2D E6400 @ 3.2 GHz, 4 GB RAM
