Yeah, your problem is that you bought a 19" LCD with a 25ms response time. You are going to want to return it. The response time you NEED for gaming on a 19" lcd is at least 16ms, any higher and you'll get the ghosting your talking about.
Don't feel bad though, I did the same thing before I learned about LCDs. I bought a 19" LCD with 25ms response time, Thought it would be great, then... it was just unplayable, made me sick if I played games on it too long.
But yeah, make sure you're using it in it's native res (1280x1024)... that might help a bit. I'd return it though. There are some good options for 19-20" LCDs though.
1. Dell 20.1" 2001fp 16ms(starts at $750)
2. Sharp 19" LL-191a 16ms(starts at $650)
3. Viewsonic 19" ... 16ms(don't remember the price)
I've heard good things about all of those, umm... there are a few others. remember though, a 17" LCD has the same screen size as a 18-19" CRT. And 17" LCDs are generally better for gaming versus 19" LCDs (17" 25ms is generally much better then 19" 25ms)
hope this helps.
*edit* heh, sorry... you asked why you see the ghosting too.
Well, the response time I was talking about is the pixel response time (it's basically the speed the the pixels can change colors). If the pixels can't change colors fast enough then you notice ghosting, which is just the pixel still trying to change the color. In games you would see it a lot because of the fast movements you make (you may notice it if you run by a black object on a light background).
This should give you a very basic understanding of how response times work.
The response time claimed isn't always accurate (for instance some 20ms LCDs are faster than other 16ms LCDs) but it gives you a good idea of what to expect. */edit*
