Its hard to take you seriously when you can't even be bothered to read what you just linked. The NEC had a better contrast ratio, the NEC has better colors (dE doesn't paint the full picture, TNs are 6bit and IPS are 8bit - IPS will basically always have better colors), the NEC has a far more even panel, and of course viewing angles are no contest.
Input lag between the two is almost nil (33ms vs. 36ms)
And that is assuming DigitalVerses got it right. TFTCentral.co.uk puts the NEC's input lag at 20ms.
You also keep looking at the black point and claiming better blacks. Well, not necessarily. Sure, the blackest black will be blacker on the Acer than the NEC, but what about one step up? Is it distinguishable? That is something you need to know before simply claiming better blacks.
Contrast difference is less than 100 between the two=neglibile to most but the black level is a big difference (0.05) especially for gaming and movies, dont try to call me out on the black level saying that isnt a big diff, you know that is BS.
I get it you do not like TN's, keep that garbage to yourself unless that OP was considering something responsive like the Dell U2410 over a TN for color work AND gaming or being retarded and sitting 10 feet to the left of their monitor and wondering why their TN looked bad.
Most people will never be able to tell the difference unless they have the panels side by side and calibrated. For gaming and movies this 200$ Acer clearly should be the better choice.
I can't take you seriously either as you have done nothing but waste my time. Some times I wonder while people even ask on here about budget monitors for gaming knowing some one is going to recommend the NEC or HP due to their viewing angle and ergonomics.
