S2716DG, refurbished replacement red tint

I was having flickering issues so I RMA'd my S2716DG. The replacement I was sent has a red tint to the color and I can't adjust the settings to get it to go away. See the comparison between left S2716DG (old) and right S2716DG (new). Both monitors were factory reset before the picture. I switched cables and ports to ensure it wasn't my card or the cables. Does anyone have any suggestions? Did they send me a bad replacement?
