No, it's a gradual shift in uniformity as you approach the edges, but is much worse on the left side. To illustrate, I divided the screen into a 3x3 grid and took 9 readings with a colorimeter and recorded the results below. The charts on the left are at the brightness level I personally use, and the ones on the right are at roughly 120 cd/m² in the center of the screen. The 1-200k color temp shift on the right is pretty minor and doesn't bother me, but the 4-500k shift on the left is large and very noticeable. The left, particularly the lower left, appears yellowed and faded. One of the reviewers on Amazon did the same thing and said this: When calibrated centrally to 6500K white balance (measured 6527K), I obtain readings from 6168K (- 6.1%, left lower corner) to 6944K (+ 5.6%, right upper corner). That is over 11% difference across the screen and shows a visibly noticeable warming of colors from right to left, especially on a full screen solid white background. I went ahead and cross-shipped a 2nd monitor yesterday. Hopefully the new one will be better. Truth be told, I'm tempted to keep the best of the two, even with the problems, as I'm desperate for a new display right now. It's still much better overall than the Samsung 40JU7100 I purchased a couple weeks ago and returned.
