NEC Unveils 29.8-inch MultiSync Professional LCD Monitor
The NEC MultiSync LCD-PA302W features a 29.8-inch panel with a native resolution of 2560 x 1600.
NEC has taken the wraps off the newest member in its MultiSync series of the professional LCD monitors, the LCD-PA302W which features a 29.8-inch GB-R LED backlit IPS display with 10-bit RGB color.
The monitor provides a native resolution of 2560 x 1600, a 1000:1 contrast ratio, a brightness of 340 cd/m2, a 7 ms (GTG) response time, and viewing angles of 178° / 178°.
The LCD-PA302W includes DVI-D, DisplayPort, HDMI and mini-DisplayPort connectors and will be available in black and white color options. Though NEC hasn't provided any information on the monitor's retail pricing, they have confirmed that it will begin shipping beginning October 25, 2013.

@ioconnor Not sure why you are having driver issues. I run two PA301Ws @ 2560x1600 off of 2 Mini DisplayPort outputs from a MacBook Pro all day.
@back_by_demand The predecessor to this monitor, the PA301W, was also 16:10 aspect ratio (2560x1600).
@10tacle There is a whole lot more to a PA monitor from NEC than just 300 vertical lines. And folks who are buying monitors like this aren't going to stop their business for 1 to 2 years to wait for 4k monitors. For a business expenses like this are tax deductible.
@mcgee101 Once again, there is a lot more to a PA monitor than just resolution. Go read a few reviews of the PA301W and you may start to understand. Regardless, the features that make these monitors so unique and valuable to a graphics professional are largely irrelevant to the average home or business user. For those that need the features, the price is justifiable. For those that don't need the features, buying a PA301W or PA302W would be a waste of money.

Additionally, it looks like they changed the port layout from the PA301W. A 301 had 2xDVI-I Dual Link (capable of both DVI-D digital and DVI-A analog input) and 2xDisplayPort 1.1. The reason for the 2x on each was so that you could hook up each of two computers to either pairing. And because of course HDMI can be converted to DVI, you could also input HDMI (and HDCP is also supported). The new monitor forgoes the 2x strategy and instead gives each of 4 different input types: DisplayPort, Mini DisplayPort, HDMI, and DVI-D Dual Link. I can't say that I am entirely a fan of the new layout, especially the inclusion of Mini DisplayPort when the box already includes a Mini DP to DP cable. I understand why including an HDMI port was a good idea--it makes it easier to hook up for monitoring an HDMI feed--though personally I could care less.
In other news, the power consumption dropped precipitously (155W for PA301W, 87W for PA302W). Running two PA301Ws is like having a small space heater going.
The Adobe RGB coverage remains largely the same (98.2% for the PA301W, 99.3% for the PA302W). My personal PA301Ws have consistently been able to achieve 99.5% of Adobe RGB so potentially no gain there for me.
