Did you have a 2407WFP or a 2407WFP-HC? The later had really bad ghosting and lag.
As I said it doesn’t bother me, neither does the AG coating to be honest and I had some good CRTs before. I can still be pretty good at games and seem to be able to play against players with 120 Hz monitors
The input lag on the U2711 is lower than on the 2407WFP anyway. I think the U2711 is 15 ms or thereabouts then again the 2407WFP was only around 20ms!! I have looked into the 2209WA input lag and that measures around 22ms which is worse than both the 2407WFP and the U2711.
I've been trying to remember which one it was. Someone off here bought mine a few years back. *EDIT* checked my trust, it says he bought a 2407WFP from me, so it's most certainly the one with 25ms lag (the good one). The lag was without question noticable to anyone who had come straight from a CRT - you might not have cared about it day to day maybe (I did), but boy was it noticable side by side, no one could have said they couldn't see it, there was a BIG difference. It's the reason i got rid of it (was into counter-strike back then).
And by TFT central, a site I trust more than others:
2407: 23.7 ms
2407-HC: 34.3 ms
U2711: 28.1 ms (gaming mode)
2209WA: 9.0 ms
So adding my thoughts, if you think you might be sensitive to input lag, remember the days of CRT and know LCD's do not compete on input lag (don't confuse this with refresh rate woes), you need to aim for under 15ms, or prepare for disappointment.
We've got some stores here that have a Apple 27" Cinema Display as demo model and you can just surf on them and stuff... I guess that would be comparable to the U2711 and Hazro 27" as they have the "same" screen right, so maybe I can do some testing on them
Afaik, the Apple doesn't have scalers so input lag is rather low on that one, lower than the u2711 for sure. Anandtech says it's 12.73ms against a CRT:

I really do predict the non-scaler versions will be the only 27-inch LCD's someone sensitive to input lag will be able to live with, just comes down to how pliable/decent you can get the contrast and colour settings without a colorimeter, which i guess we'll find out next week with badass' review.
