Thanks all for your help. The new one is better but not perfect. Still a bit of hue on the left side. I don’t think i am gonna try a 3d replacement because I don t have the time for this. I may deal directly with AppleCare later.
I think the bleed is due to the screen connectors that applies a bit of pressure. And the only way to really see it is to put a pure black image at 100% brithgness in the dark.
It s sad Apple still use lcd tech, a mini with oled will be awesome…
