As I've said in the past, DisplayMate is designed to highlight weaknesses in monitors, and those issues may never present themselves in the real world. But in the case of the 3090WQXi, its outstanding performance under DisplayMate is carried over into real world applications. Viewing and editing high quality images in Photoshop using this monitor was an absolute joy. Not only are the colours scarily real, but the complete lack of high or low intensity compression means that you're actually seeing detail that simply isn't there on lesser screens.
Despite the fact that the 3090WQXi comes out of the box looking fantastic (Dell take note), anyone buying this screen is likely to want to calibrate it themselves, which highlights another great feature - self calibration. If you want to calibrate a monitor, you usually have to use a sensor that plugs into your PC and a profiling utility, but with the 3090WQXi you can plug a sensor directly into the screen and let it calibrate itself. If you're using two monitors, you can even match your second display to the first, reducing any variation between the monitors. The self calibration feature only works with an X-Rite i1 Display Sensor though, so it may mean investing in some new hardware if you want to calibrate this way. That said, if you've ordered multiple 3090WQXi screens for your business, it does mean that you can calibrate each and every one of them to match each other, without ever having to boot up a computer.
Since I've already mentioned that the 3090WQXi uses an S-IPS panel, it will come as no surprise that it's an 8-bit screen with 16.7 million colours. Colour depth is something that you need to be wary of when buying an LCD monitor these days, since many manufacturers inaccurately cite 16.7 million colours for their 6-bit panels, when in reality these screens can only manage 16.2 million colours by employing dithering techniques. Talking of colours, the level of adjustment available is impressive - there are various colour temperature presets along with an sRGB setting that's far more agreeable than on most displays. But it's the Programmable colour setting that's most interesting. Unlike most monitors, the Programmable setting doesn't give you access to Red, Green and Blue sliders under the OSD, instead it lets you adjust the colours using NEC's NaviSet software. Within NaviSet you're able to customise your colour profile in both RGB and CMY, depending on whether you work in additive or subtractive colour models.
