Does this make 3D a novelty feature? It depends on how much you will use it. In its sweet spot the d2357Ph does provide immersive pictures that leap out of the screen, and passive 3D makes replacing broken glasses or buying more very cheap, but the limitations are clear.
There is also a further problem in that filter film used in passive 3D dims the brightness in 2D. AOC doesn't quote a brightness figure for the d5357Ph and while it isn't overly noticeable it is again a small compromise compared to dedicated 2D models.
Consequently cost becomes a big factor and with an RRP of just £205 and backed up by a three year warranty AOC has certainly made the d2357PH one of the cheapest and most stylish 3D monitors on the market. There is a lot to the bundle too because AOC includes HDMI, VGA and 3.5mm audio cables and there are even tiny integrated 2x 2W speakers which, while tinny, are good enough for audiobooks or podcasts.
That said 3D remains the problem. Remove it and you will find specialists like the aforementioned i2353Fh which has undisputedly superior 2D, even slimmer dimensions and costs £65 less (almost 30 per cent). As such, 'good for a 3D monitor' is still relative praise.
If you're after a budget 3D monitor, the AOC d2357Ph breaks new ground in design and price, while its passive 3D implementation means glasses are incredibly cheap. However, the 3D performance isn't on a level with active solutions and darkens the panel slightly even in 2D - and with higher-quality IPS-based 'pure 2D' monitors available from the same manufacturer, you have to really want that third dimension.
