The display panel market is driven by economics, an that is not leaving much in the way of a 32-inch form factor with other than 16:9 aspect ratio. But my trust NEC PA302W has served me well and continues to do so—it has an unbeatable color gamut and the most neutral grayscale I’ve seen in any display (which stems from the type of backlighting it uses).
I don’t know where things are going, but pixel density is a confounding practical problem for examining images critically.
The models with the black bezel are gone, but the ones with the white bezel are still available, e.g. the NEC PA302W-SV 30" 16:10 IPS Monitor with SpectraView II.
I just recalibrated my NEC PA302 and the gamut is as usual outstanding.
