Whenever the BBC has broadcast programmes or events in 3D, there were other technical changes made to the channel that accompanied it. The BBC's first broadcast of the Wimbledon finals in 2011 saw the screen resolution increased from the usual 1440 by 1080 to 1920 by 1080 between 13 June and 6 July. Equally, the same occurred for the 2011 "Strictly Come Dancing" final when the resolution was changed between 8 December 2011 and 5 January 2012. An increase to 1920 horizontal resolution was again observed on 30 May 2012 as part of the preparations of 2012's 3D broadcasts.
