Summary: I ordered this monitor after extensively research for 24-27" monitor. I almost purchased NEC but it's not sold by Amazon and quite pricey. Based on good reviews here so I gave it a try. Like another comment, my monitor generated high pitch noise at the first plug in. I unplugged USB keyboard and it was all quiet. However after moving the devices around different ports, it didn't seem to generate the noise later on.
Summary: I really wanted to love this monitor. The price point is great for a higher-end monitor. It's a wide gamut, factory precalibrated model. I bought two, and the colors were indistinguishable straight out of the box, and images are very attractive and natural. It has a good number of interface options (DVI, display port, VGA (though note that via VGA one can't support the the native 1900x1200 size), and HDMI.
Summary: The number of monitors in the market today is really mindboggling, perhaps unnecessary. Numerous price points, numerous sizes, display technologies, etc. I am a hobbyist photographer and wanted to upgrade from my 8 year old Acer P221W. It was a fine monitor for its time, but I wanted something that would give me great color reproduction. Various reviews led me to try the Asus PA249Q.
Summary: Liked build quality, but watch out for sharp like knife corners - I got a nice bleeding scratch while handling it. I tried 2 monitors but all had substantial back-light bleeding from lower corners. IPS glow is too apparent. I also have doubts about accuracy of factory color calibration: switching between sRGB and Adobe RGB I got huge difference in color rendering accuracy, sRGB having greenish hue, which tells me that factory pre-calibration is not up to professional...
Summary: I get this horrible high-pitched whine when the monitor is in sleep mode. I hate it. I'd try to get it replaced, but the amount it'd cost me to ship it back to NCIX/Asus for a replacement and the fact that the monitor is perfect otherwise just makes me suck it up. Oh well... Oh! And also, this doesn't come with HDMI cables, and the monitor wouldn't turn on via display port until I installed my GTX 780's drivers. Just a heads up.
Quality isn't what you'd expect from the high price

Summary: The thing I noticed immediately when I received my first monitor and turned it on was that the bottom left corner and bottom edge of the display had a sickly green glow. This isn't very impressive for a monitor sold at a premium price with claims about its excellent colour accuracy written all over the box. The colours were indeed good, but only in the middle of the screen.
Summary: Nach langer Suche für einen geeigneten Monitor in Sachen Mediendesign und Musikproduktion dachte ich, ich wäre mit diesem Monitor endlich am Ziel. Denn die Bildqualität ist schon wirklich super. Das beste, was ich je gesehen habe. Auf jeden Fall, war es der erste Eindruck nach dem ersten Einschalten. Auch die Stabilität des Monitors (inklusive Fuss) ist wirklich top.
