The iPhone X has the best display on the market, according to gadget lab DisplayMate. The smartphone, which released last Friday has received an A+ rating for its screen quality.

The iPhone X features a 5.8-inch Super Retina HD (1125 x 2436) OLED display with a pixel density of 458 pixels per inch (ppi) and a brightness capacity of 634 nits. DisplayMate named the iPhone X as having the best smartphone display, highlighting aspects, including color accuracy, full-screen brightness, full-screen contrast, contrast ratio, screen reflectance and viewing angle, among others. The iPhone X is the second device to get an A+ rating from DisplayMate after the Galaxy Note 8 was reviewed in August.

Apple’s latest smartphone is its first to release with an OLED display. The tech giant typically includes LCD displays on the iPhone line; however, the iPhone X indicates a shift in Apple’s device story. The new device is essentially new, super-premium line, different from the numbered iPhone models.

The iPhone X is also Apple’s first device to feature an edge-to-edge display and no home button. The device’s software includes various gestures, which replace the need for a home button. For example, to close an app and go to the home screen on the iPhone X, users need swipe up from the bottom of the display.

Users report it takes about two days to get used to the new gestures. Some have admitted that certain gestures are easier to learn than others. One of the more challenging tasks is finding the battery percentage icon, which is now located in the Control Center. It can be accessed by swiping down from the upper right side of the display.

Another criticism of the iPhone X display is its top-notch, which houses all of its front-facing sensors. Most reviews indicate the notch is easy to get used to; however, it does get in the way of a complete full-screen display for functions, such as viewing a video.
