DisplayMate has done a Samsung Galaxy S5 Display Technology ShootOut
and it even beat out the Note 3!!!
Here's a quote from the shootout; "Our detailed Lab tests show that there have been significant display performance improvements in almost every single test and measurement category, resulting in a number of new records for Smartphone display performance. Based on our extensive Lab tests and measurements, which we present in detail below, the Galaxy S5 is the Best performing Smartphone display that we have ever tested – and it has raised the bar for top display performance up by another notch."
This makes me want this device even more but I'm still holding out for the 32GB version,
