Below you can see a video of the changes to Xbox One that Microsoft is bringing via the March Update. It's mostly about Party Chat being on as default, and how to get more friends. All lovely stuff, however... The PAL TV users (and some places in Europe) among us will be filled with joy at the news that there will also be the option to select 50hz output. That will make your juddery response less so... apparently.
CVG report that, "According to various users currently testing the update, the change will allow Xbox One owners to manually switch between 50hz and 60hz modes from the console's system menu, for smoother television viewing."
