The most noticeable characteristic of the XPS 15 is its extraordinary display. With almost no bezel around the screen, 4K resolution, above average brightness, viewability from almost any angle, and superb colour, it feels markedly more immersive than Retina displays -- to the point where colour flaws on web pages and low-resolution installation wizards become hard to look at. Dell's togglable PremierColor feature pushes the display's palette to its limits, and looks stunning in the right applications.
