It’s barely been two months since DisplayMate anointed the Samsung Galaxy Note 8’s 6.3-inch Super AMOLED screen as the best display ever made for a smartphone.

Now, DisplayMate has once again awarded that title and an A+ grade to a display built by the experts at Samsung Display, only this time it’s not for its work on a Samsung flagship, but for the Samsung-made OLED display found on Apple’s iPhone X.

Following 2017’s hot trend, the iPhone X’s 5.8-inch OLED display has a taller height-to-width aspect ratio of 19.5:9 offering a ‘bezel-less’ look (as long as you ignore the notch). DisplayMate found that the 2.5K Higher Resolution Full HD+ display comes in at 1125 x 2436 pixels with a pixel density of 458 ppi.

DisplayMate’s extensive research suggests that the iPhone X sets OLED display records for the highest full-screen brightness (634 nits), lowest screen reflectance (4.5 percent), the smallest brightness variations from different viewing angles, and several others. The biggest factor that puts the iPhone X’s display above the Note 8 though, is apparently Apple’s own color calibration.

Editor's Pick

As with the Note 8, the iPhone X supports both sRGB/Rec.709 and DCI-P3 color gamuts, with the former used for standard visual content, and the wider, latter gamut found mostly in 4K TV sets and digital cinema screens.

While the Note 8 was also roundly praised for its color accuracy, the folks at DisplayMate believe the iPhone X goes above and beyond in this regard, stating:

“It is the most color accurate display that we have ever measured. It is visually indistinguishable from perfect, and is very likely considerably better than any mobile display, monitor, TV or UHD TV that you have.”

Samsung will no doubt be looking to regain its title next year with the Galaxy S9, but it’ll be interesting to see if the South Korean giant can match Apple’s impressively precise color calibration. Does Samsung have what it takes? Let us know in the comments.
