I thought I would be sensitive to ghosting, but my new Gateway FPD2185W doesn't seem to have any sign of it. Nothing that makes a difference to me, and I've been playing UT2004 a whole lot just to see if the LCD creates some visual problems in fast FPS gaming. I would assume the 2405/2407 would be very similar. The game is just flat out amazing to look at.
You can run some tests that are available to show ghosting, and those tests will reveal that ghosting does occur on even the best of LCDs. But the tests I've seen use bright colored blocks displayed on white or black backgrounds, and the ghosting is notable but not significant. When you are playing a game, however, colors are rarely contrasted like that. When I move quickly back and forth, say, looking at my weapon or an object near me, I just don't see anything wrong. Things blur in general because they are moving. There is no smearing of colors or lagging. It frankly doesn't look any different to me than when playing on a CRT, since things are happening so quickly. It does not affect gameplay at all, or my ability to quickly spot moving objects, etc. I just don't get the feeling that the display is slower than a CRT, and it is a helluva lot crisper and clearer than a CRT. For me, that is a better tradeoff even if ghosting was an occasional issue.
Trust me, when you remember what the ghosting looked like on LCD several years ago, and then look at them now, the difference is huge. I don't think you'd have anything to worry about if you are looking at the Dells as it relates to ghosting. Of course, if you spend all your time trying to see it, you likely will. I just play. I remember when I got my first Sony Trinitron. All I could see was those two damn horizontal lines. One day, I just forgot about them. Loved the monitor. LCDs have different issues from CRTs, but once you've gone widescreen (which is somewhat like going from dial up to broadband), you'll be willing to accommodate the typical LCD quirks, especially for the excellent LCDs, like the Dells.
