Throw your LCD into the garbage.
Seriously though. If you have a decent quality LCD and windows XP, use your "Clear Type" setting in your "appearance" applet under "effects". You should notice the text sort of "antialias's" so to speak taking away most of the jaggies. In reality, its really only "smoothing the text" by blurring it slightly.
You cant beat a CRT though. The only reason I can see getting a LCD over a CRT is to save desk space. Thats it. People will say, "My electric bill went down 500.00 per month switching to an LCD. They are lying. You will only notice a few cents saved per month and thats if your really looking. And heat? LCD's dont throw off as much heat as a CRT, but they do throw off a decent amount. Other than that, Gaming isn't as good as a CRT nor is just reading plain text. You would have to spend quite a bit of money to get an LCD that is comparable to even a mid range CRT quality. I know, I have taken the LCD route. I now have my 19" Dell CRT mounted in my wall so its flush. Flatter than any LCD LOL.... Theres more than one way to save desk space.
