Sorry for being harsh, but this is complete crap, yea the monitor is great for the price but no MVA/PVA monitor can have outstanding contrast due to the very well known issues.
So in short, even 500:1 contrast on IPS screen will look alot better then overrated 1000:1 on PVA/MVA panel aka black crush/shadow detail issues all over, which are impossible to avoid proven many times by now. Your review looks good overall but i'm totally confused how can someone have decent knowledge about monitors, and yet saying something so wrong..It's ridiculous.
He has a thing for measured contrast ratio. So even if the viewing angles and gamma shift were so bad that only a small circle in the center of the screen could actually achieve such high contrast he would still claim it's a superior monitor to any IPS ever produced. These Benq screens, albeit good value, are a pretty good example there is much more to a great monitor than just high measured contrast ratio.
