@liss Do you also have the Dell P2415Q 4K monitor? If so, I just got one and am facing subtle horizontal gray lines on white, and was wondering if you’ve experienced this issue. Hoping this one is just a lemon and that a replacement will suffice.

@jackwellborn I have two of them, don't see any grey lines, white is perfect.

@rulix @liss Thanks. The replacement is own its way.
