The cause appears to be the difference in refresh rates between UK and US TV sets and services. In the UK, the TV broadcast standard is 50Hz, or 50 frames per second (FPS), which most television set top boxes including Sky, Virgin and Freeview services output. In the US, the standard is 60Hz or 60FPS, and by default the Xbox One is set to the US, not UK standard.
"Assuming the reports are true, this represents a significant issue Microsoft has to address," Richard Leadbetter of visual testing company Digital Foundry told Eurogamer. "Displaying 50Hz video at 60Hz means that every sixth frame will be a duplicate, resulting in noticeable judder on a lot of material – scrolling text on news channels, fast pans in TV and movies, and the left to right sweep of the camera in football matches."
Microsoft said that it is aware of the issue, but did not have a comment at the time of publication.
What a colossal fuck-up. How on Earth do you release a product so focused on television and not realize that the UK has a different broadcast standard? You had one job.
Heads are undoubtedly going to roll over this.
