After my own U2412M arrived and I got to see its viewing angle characteristics myself, I realised what the Hardware Canucks picture is showing - if you go off-centre horizontally
vertically (the HC horizontal pic is taken from above a little), you get a more significant contrast shift/darkening than at a horizontal angle alone. The other reviews depict the screen off-centre horizontally or vertically, but not both at the same time.
Seems to be a dirty little secret of the e-IPS panel type. I reconnected my e-IPS 2209WA the U2412M was replacing, and it had the same characteristic (either I hadn't previously noticed the issue, or I'd forgotten about it). Not that it's anywhere near as bad as TN when, say, looking up at the monitor while sitting on the floor. And viewing the monitor in person, the change in image at the sort of angle shown in the HC review pic does not appear as extreme as conveyed in the photo.
Yes, there are a couple things at play here as well:
1) The anti-glare on these screens, as well as on the 2209WA is a bit aggressive and the way it diffuses/disperses light in a properly lit room works to reduce visual contrast from off-angles. It gives a slight greyish "haze" over the picture when viewed from an angle in general, and if it also reflects light, the haze becomes a bit stronger.
2) IPS monitors in general lose contrast from the side and upper angles because their black levels "rise" and become a bit more greyish.
What AkG did that most other reviewers don't do is use the monitor as it's intended: In a normally lit room.
