Asus must have been naughty and shipped a golden sample for review.
I have tried two of these monitors. The out of the box calibration was wildly different for both. But the biggest issue is uniformity .
Without uniformity compensation the first one was horrible. Bluish towards the bottom of the screen and really bad in the lower corners. With compensation on it evened out top and bottom but quite a bit cooler towards the left side than the right and brighter too. Finally there was a horrible weird disco light backlight bleed at the top.
Without uniformity compensation the second one was warmer towards the bottom. Nowhere near as offensive as the first unit. With compensation top and bottom match but like the first one a bit cooler towards the left side However the luminance is very uniform. Minimal conventional backlight bleed at 2 points near the top corners.
What I dont understand is both monitors included calibration charts showing exceptional uniformity measured at the factory. I wonder if these monitors dont travel well.
