Samsung's Galaxy Note 5 and Galaxy S6 Edge+ are already racking up accolades ahead of their August 21 launch. The quality of a smartphone's display is often a top priority among shoppers and according to the screen experts at DisplayMate, Samsung's new flagships can't be beat.

It's probably safe to assume that since the display on the Galaxy Note 5 is the same size and resolution as what was found on its predecessor, most thought they must be identical. That conclusion couldn't be further from the truth.

Dr. Raymond M. Soneira, president of DisplayMate, notes in his extensive report that the Galaxy Note 5 is the best performing smartphone display they have ever tested. The Note 5 matches or breaks new records in a wealth of categories including highest absolute color accuracy, highest peak brightness and highest contrast rating in ambient light, just to name a few.

The Galaxy S6 Edge+ is no slouch, either. The biggest takeaway, Soneira says, is the fact that the flexible plastic substrate used in its display is now essentially the same as traditional glass substrate.

Also newsworthy is Soneira's claim that it is absolutely pointless to further increase the display resolution and pixels per inch of similarly-sized mobile screens (he described it as a marketing wild good chase into the stratosphere).

With screen size and resolution already functionally maxed out, Soneira suggests manufacturers should instead focus their time and resources on improving real-world display performance in ambient light.
