Again I would say yes the 2490 is better than the 245T because the 2490 uses S-IPS and teh 245 uses S-PVA.
Also the 245T lacks pretty much all of the features the 2490 has including a 12 bit LUT, Colorcomp, Overdrive, 4 year warranty etc..
The 245T comes a nice under 800$ and is TN panel, i can't understand why are people giving others advices if they don't know the right.
I maybe won't come again to this topic, don't have much time to read here, so theres no need to give any reaction to my post.
So if it won't have bad backlight bleeding and will be as fast as my 930BF, than it will be a great monitor, no matter what specifications.
