PCM2, just a question:
There's been a lot of criticism on the XL2410T having the dark ghost trail with AMA enabled. This is usually tested using PixPerAn.
Now, If i move a black object on a white background on my monitor, and look REALLY REALLY close and follow the object and possible location of the trail with my eyes, I do see that the XL2420T has this too. (I never had a XL2410T, so I don't know how it compares to that) However, it is so difficult to see, that I actually don't see or notice it at all anywhere else... I actually cannot spot it on anything but a very white background.
So my question is, is the PixPerAn test still a fair test if you're using (I'm guessing) a DSLR with a very quick shutter? If there's a ghosting trail, won't it be much more visible on a 60Hz screen than on a 120Hz screen? For the camera you're using for the test, it probably won't be much different, but it is for your eyes I reckon?
In any case, I am very very satisfied with my XL2420T. There's no way I made a wrong choice buying it, especially considering I hate glossy screens and thus the Samsungs were no option for me.
It is often the case that PixPerAn will highlight certain artifacts or imperfections that in most cases would go unnoticed during real-world testing. The common scenario itself of the red car with yellow driver moving across a blue background is itself fairly constrained and artificial in terms of the pixel transitions occuring and the speed at which they are occuring. Furthermore it represents what is captured by a camera at high shutter speed - in actuality it doesn't say how persistant or long-lived the trailing is. That is why in my own reviews I make explicit note of how the responsiveness of a monitor fairs in practice in a range of game titles. Having said that I do still think that PixPerAn is a useful comparative tool and it is a good way of indicating the existance (or absence) of a particular issue. It also gives some indication of the strength of that issue - for example you can see how bold and extensive trailing behaviour is. Because subjective assessment relies on personal perception, which is an individual thing, there is certainly room for both of these things.
