DisplayMate has one of the first Galaxy Note 4 smartphones in its possession, calling it the best display on a smartphone, ever. Samsung sent the company a pre-production model of its upcoming 'phablet' to test out, with its new 2560x1440 display.
DisplayMate played with the pre-production Galaxy Note 4, where it said: "It provides lots of image detail - it can display four complete HD 1280x720 images at once. The display has Diamond Pixels and Sub-Pixel Rendering with 518 pixels per inch (ppi), providing significantly higher image sharpness than can be resolved with normal 20/20 Vision at the typical viewing distances of 10 inches or more for Smartphones, so the display appears perfectly sharp".
By the end of its piece on the Galaxy Note 4, DisplayMate said that the display on the Note 4 "matches or breaks new records in Smartphone display performance".
