I picked this up during the $999 sale; moving up from a U3415W. My panel was able to hit 120hz with no coil whine or other aberrant symptoms related to high refresh rates.
That said, I did ultimately experience a couple issues that resulted in my request for an exchange:
Significantly stronger BLB/IPS Glow in bottom left compared to rest of screen. Extremely distracting during gaming; highly illuminated in reference to surrounding blacks.
Right side of screen has a visibly yellow tint compared to left. Not very noticeable until you stretch a lightish window over the middle of the monitor and drag it left/right, watching the hue of the white as it travels between sides. Once I was aware of it there was no escaping it during normal desktop use (not detectable during gaming). Very frustrating.
Other than these two issues, the monitor is incredible. This feels like pure buttery bliss with little to no quality loss coming from the U3415W (60hz no g-sync). Fingers crossed for a better lottery pick on the exchange!
I also grabbed one during the $999 sale. My brother got one, too, so I have two to compare. Like in the TFT Central review, the glow (IPS glow and/or BLB...probably a combination of the two) originating from the bottom-left corner is seemingly unavoidable.
However, you can greatly reduce it by careful placement of the monitor in relation to your eyes:
Distance: 36-40" from eyes to screen
Height: such that your eyes are about 2/3 from the top of the screen (1/3 from bottom)
Brightness: keep with TFT Central's recommendation and don't exceed ~38
This was the only defect I experienced (annoying but not a deal breaker). Zero scan lines that I can tell. The rest of the monitor is flipping fantastic and mirrors TFT Central's review. 120Hz G-synced Witcher 3, DAI, MEA with a 1080Ti is pretty special.
cre3d, let us know how your replacement compares. Unfortunately, I have a feeling it'll be exactly the same. If you still have your current unit, give my steps a shot.
