I’ve long maintained that the value of 8K displays is not in the increased pixel count. There’s a limit to the resolution that humans can discern on video screens at normal seating distances, and increasing the pixel density beyond that limit offers no advantage.

But where, exactly, is that limit? More specifically, do 8K displays offer any benefit in terms of perceived detail compared with 4K under normal viewing conditions? In collaboration with Pixar, Amazon Prime Video, LG, and the American Society of Cinematographers (ASC), Warner Bros. recently addressed this question in a well-designed, double-blind study to see if people could discern a difference between 4K and 8K with a variety of content.

The results are predictable and exactly what many of us suspected.
