Glad your VA monitor is working out for you, I've been meaning to try out a VA monitor for a while now, to hopefully give me the confidence to buy a VA panel TV. Not sure why IPS screens are such an issue, I know they have a 'sparkle' effect that might be something to do with it.

I have had the same experience with Benq monitors, I suspect they are either updating designs/firmware but not changing the product name/code, or due to supply issues with panels/chips. I keep an eye on ebay for older screens that so far I have been able to use, so far I have acquired five! two in my home office, two in my office office and one as a tv.
