It's also worth mentioning that NEC has managed to develop the best OSD system I've ever seen on a monitor. The controls run around the bottom right corner of the screen, giving you dedicated up/down and left/right controls, but the best part is what happens when you press the Menu button. While most monitors expect you to psychicly know what each button does when in the OSD, the 3090WQXi actually tells you by applying overlaid labels on the screen next to each button. This makes navigating the OSD an absolute breeze, instead of a frustrating chore - well done NEC!
The 3090WQXi also features a dynamic brightness setting. Next to the power button is an ambient light sensor, which will adjust the brightness based on the current ambient lighting. However, there is a second dynamic brightness setting, which will adjust the brightness of the screen depending on the amount of white currently displayed on the screen.
Like previous 30in monitors, the 3090WQXi sports a native resolution of 2,560 x 1,600, which gives you a generous amount of desktop real estate. This means that you'll need a graphics card with a dual-link DVI output to run it, but even modestly priced cards come dual-link equipped these days. NEC quotes a grey to grey response time, of 6ms, but is also honest enough to list an off-on-off response time of 12ms. Either way, NEC has managed to keep the response time commendably low, considering that this is one area where IPS panels have been traditionally weak. The low response time, coupled with NEC's RapidMotion processing, made for smooth moving images too, with no discernible smearing. It's good to see that even though watching video and gaming isn't key to the 3090WQXi's remit, NEC has still ensured that it performs well in this area.
As with all high end monitors, especially those from NEC, the 3090WQXi carries a premium price - with a street price of over £1,500, it's considerably more expensive than the majority of 30in displays available. However, it's also worth remembering that the 3090WQXi performs considerably better than any other 30in monitor I've seen, and if you need the best possible image quality, you're not going to mind paying a little extra for it.
The NEC MultiSync is far and away the best 30in monitor I've ever had on my desk. The image quality is first rate, with supremely wide viewing angles that show what an S-IPS panel is capable of (take note Dell). The design is excellent, with extensive physical adjustments and the best OSD/control system I've ever come across.
If you're a professional image editor, or work with CAD or 3D modelling, you will simply love this display. The pivot mode will make working on high resolution portrait orientation images far simpler, while the self calibration and multi-screen calibration matching, makes the 3090WQXi particularly compelling for multi-screen roll outs. There's no denying that this is an expensive display, but considering its performance and features, it's worth every penny.
