Excerpt: NEC's new EX231Wp is a business monitor with a 1,920x1,080 resolution PVA panel and a fully-adjustable stand. PVA (Patterned Vertical Alignment) is a variant of the more common VA technology, and is meant to give better contrast ratios than normal VA panels - which themselves are typically superior...
Conclusion: The EX231Wp I think is well summarised by it's 'Cool Office' name. Here you have a screen which looks very attractive and sleek on any desk, featuring a very thin bezel and stand and a slim profile from the side.
Pros: Excellent black depth and contrast ratio from cPVA panel, Very good feature set for power saving including auto brightness, human sensor and ECO modes, Good potential office monitor thanks to feature and function set
Cons: Some missing features like D-sub and HDMI, Slow pixel response times in practice, Medium input lag, not really a gamer orientated screen
