Colours are bright and vibrant and makes my old monitor look dull. The monitor it self seems well made. As for colour calibration it's very good. There was very little after I used my xrite calibration tool.

Nice monitor with great ergonomics! Not quite as sharp as I'd have thought (compared to retina displays), but still a great quality screen! Good for content creators like myself, as it has a great colour range but not great in the blacks.
