Hello, 

I have purchased two P2715Q monitors. One is a revision A03 and the other is an A04. Ironically, the one that was manufactured more recently is the older revision. 

Anyways, the issue I am having is with the color calibration. Both monitors out-of-the-box have a different hue when put together side-by-side. I factory reset both monitors and reset the color settings on both to default and the colors are still different between the two. One of the monitors came with a color certification sheet, the other did not. 

The newer monitor (with the older A03 revision) has more of a warm hue when looking at whites. The older monitor (with the newer A04 revision) has more of a cooler tone with the whites and looks more accurate.

If the marketing on this monitor claims each monitor is factory tuned at 99% sRGB with a color calibration factory report certifying that each monitor has a deltaE < 3. That means you get precise color coverage right out of the box... then why am I seeing such a variation between the two?
